Wacked out Touchscreen... - Touch CDMA General

Well, my touch screen has pretty much gone crazy. It keeps picking up a touch in the bottom right hand corner repeatedly, even though nothing is touching it. So it is at the point where the phone just keeps vibrating and spazzing out on the table. I've done a hard reset already, so i believe the problem is likely hardware related, any possible ideas to fix this? I did rub the phone with some tooth paste earlier though.

rub the phone down with toothpaste? hoping for some minty fresh conversations?? only thing that would help with would be fixing minor scratches in the surface and even then it would have to be an older style toothpaste (none of the new gel types) as it would need to be a minor abrasion type
Sounds if the screen is picking up a ghost touch - then your digitizer is coming apart (sometimes can also be detected by seeing an "oily" something under the screen) and the only fix is to replace the screen
You can find some on EBay as well as the kits to do the operation as well
and the directions can be found around here and over at PPCGeeks just search "replacing the screen" or "replacing the digitizer" and you should get some threads with a PDF attached and where to find it all

Yes, actually there looks like a giant blob of liquid underneath the screen, but it moves around so it is actually liquid... I bought this phone second hand, so i assume its probably been through the washer. Water damage stick is red too. However, after leaving the battery out overnight, the ghost touches went away.

surprised it works had it been dipped in a washer LOL
the fact it could still be a digitizer issue as it "looks" as if an oily or water bubble under the screen is moving about when pressure is applied
Best bet, get a bag of rice or a handful of those desiccant packages from a local shoe or electronic store near you, remove the battery and back cover and SD card - put rest of phone in a baggy with some rice and the desiccant packs, close up the baggy and walk away for 24 hours or so
If it is water it will be gone definitely then, if it is the digitizer separating, you will still have the blob under the screen as it is the result of the polarized screens moving to and away from each other causing the look of a rainbow weird oily blob
Once you know which it is, you can decide how to go from there -deal with water (which should be gone after the baggy treatment) or replace the digitizer from EBay

I drop my touch dual...

Ok, long story short, this morning I was running and my nike drop flew off my clumsy hand, drop on the floor and bounce like two times.
The touch dual was like two meters away from me, screen facing down.
I approach it slowly preparing myself for the worst. I stand beside my nike looking down, it is a mess, white and gray dust completely covered the rubber coating. I got down and pick up my poor nike, flip it over and to my dismay... I got a sms from my colleage that my boss is angry.
Haha, its still working apart from the dust. I tried searching for any sign of damage after cleaning it with wet tower later on, but cant find any. Apart from 2 small scratches on the silver side(which I dont even sure if it is from the fall), my nike look out of box. Another thing is that the bottom of the front sliding body feels abit lose(can be push to slide left and right), not sure if it is from the fall.
So the story is, dont even bother with crystal case or silicon case, the rubber coating of the nike is strong enough to withstand a fall from your normal hand level and bouncing twice over two meters without so much as a scratch. Even the screen protector is unscratch.
haha

funny....my niki dropped from my computer table too and it was also face down he he he he maybe it's buttered side
Hm, one time dropped my nike and my battery fell off - when I switched my device back on (after placing the battery back in place, of course ) all of my contacts were deleted .
That was the last time I used a homebrew distro...

Likely Death to my G1

today was a horrible day...
apparently leaving your g1 in your pants while they are in the wash doesnt work so well.
does not power on
anyone have any idea what can be done to bring it back or is it most likely fried
and if it is done then does anyone want to buy it as is?
I guess this is an excuse to get a g2
*UPDATE*
I guess no G2 for me just yet.
My phone works great now. Did not do anything special. Did disassemble the phone though so I can wipe down any residue i saw on main components such as the keyboard.
My advice to anyone that has this misfortune is not to rush things. I think i turned my phone on 2 days too early but I got lucky and it did not affect my phone. I figured this out because there was a lot of visible moisture in the screen when the backlight turned on. The keyboard was not functioning correctly either.
I did leave it in rice for about 36 hours but I do not really think that did much as far as the drying process goes. Best thing to do is go to a hardware store and pick up a torx driver set(mine was $4 at Home Depot and it was 36 piece set including torx philips hex slotted and pozi) open up the phone *be careful* of course and let it air dry for 3-4 days (not absolutely necessary to take apart the entire screen but if you feel comfortable go ahead). While it was open I wiped down the main board and the keyboard. I did not take apart the screen because I just did not want to take any other risks(mostly because i knew the screen worked) even though there was moisture, I knew it would eventually dry out. But the key to all of this was patience(I know its tough to go 3-4 days without your baby).
the link for the service manual is http://mikechannon.net/PDF Manuals/HTC Dream SM (A04).pdf
Most of the time, phones can live through the washer and live. You MUST take out the battery and do NOT attempt to turn it on for atleast 48 hours, as you will likely short out the phone. Put the phone in a big bag of rice to let it soak up the water, also use a blowdryer to help dry the phone out. However, your warranty is now void, and there likely will be some remnants of water within your screen.
Yep! worst thing you can do is turn that thing on (or try) before its dry.
my g1 hasnt had a bath but other phones have (none with touch screens) and i take as much apart as possible and leave it that way till the waters gone (then like 4 more days just to me sure )
artifical drying sources reccomended (dont get too hot!!!)
I have had it in rice for about 24 hours now and its sitting on top of my dvr because it gives off a little heat so it should help the process.
just remembered that i didnt remove the sd card...
i was thinking that since it was in the washer with detergent, shouldnt i have just removed the battery and try to clean it in some type of solution...
I have read about a alcohol solutions but kind of scared and i just noticed that there is condensation around the edges of the screen
I'd say take it apart, Blow dry what you can, leave the pieces in a warm area for a couple hours, and then try putting it back together and turning it on.
anybody know how sensitive the screen is because i want to try and blow some heat on it but not sure if it will damage it

good point but im on att network using the g1 unlocked...
plus i rather not cheat my way out of it because this is my own fault
good news and bad news...
first of all it powers on and boots fine. Secondly the screen seems to be working perfectly (touch and all)
bad news i might have turned it on too early because screen still had noticeable water spots all over it. The keyboard also just spews random letters and commands (ie one of the letters controls the volume)
other good news 1.5 has onscreen keyboard
anyone have any advice on how to go about fixing the keyboard?
Advise for fixing the keyboard: take it apart and clean it.
ok well im taking it apart to clean it out and i see some residue but what should i use?
microfiber cloth?
cleaned out as much as i could but seems like the menu button is now acting up while the keyboard is still messed up
Aside from parts made of paper, parts with thin films (like the lcd), speakers, batteries, or fine parts that are difficult to dry, you can do a very neat job with 99% iso alcohol followed by deionized (aka distilled) water. This includes most (but not all) plastic casing, buttons, pcb boards, etc. Follow up with a hair blowdryer set on low heat (or if you have an electric heatgun, even better).
Get a semi-shallow dish, fill it with the solvent, submerge the part and scrub it lightly with a soft toothbrush. (probably don't scrub for polished surfaces like the exterior casing). Then directly rinse it under a stream of the deionized water. Finally, clean the dish out, fill it with the di water and scrub with the brush.
^ almost exactly what I did to recover a "dead" water soaked phone. Worked great, and learned a lot about how the phone is built
couldnt find 99% near by but got 91% which im assuming should work...
is it ok if i use bottled water(kirkland)?
oh and the spots on the screen are still there (light and dark areas)
thanks for the help guys

I bought my 99% iso from Safeway. It comes in a 16oz container. Look for it in the medical supplies aisles. Don't use bottled spring/mineral water, as that contains... minerals. You need buy deionized (also referred to as distilled) water. Distilled water contains a significantly lower amount of mineral ion, which for the purpose of cleaning electronics would be considered contaminants.
Do the spots appear to be blotches of moisture? Perhaps there is fluid trapped between the various layers of the lcd.
ok ill go check out safeway tomorrow morning. thanks for clearing up the water thing.
it looks like its moisture because after leaving it off for about 5 or 6 more hours i saw a few spots fade a little bit.
I will take the screen apart tomorrow as well. Any special instructions on handling the screen or even cleaning it?
You might want to search for the service manual for the G1. It details a complete teardown and rebuild of the dream hardware.
some sort of a miracle just occured because my phone is not acting up at all anymore and i didnt even clean it with the alcohol solution yet.
Just woke up in the morning and turned on the phone and worked perfectly, with absolutely no problem with the keyboard(except that i think i forgot a screw and a few keys are a little loose) everything works fine.
only problem is that the screen still has what looks like condensation.
but the blotches in the screen seem to be slowly fading. Gonna pop it open right now and leave it out overnight.
thanks for the help
oh and the manual has a few mistakes in it as far as procedure goes but any person with common sense should be able to get past those
Damn, thats rough man. I dropped both my old phones in the toilet(damn you superbowl, damn you!!!)and both of them worked after taking them apart and drying them off but never really worked 100% the same...
Just a note too, those were non-touch screen phones.
Best of luck.

Water under screen in HD2 (update and question)

So I posted about a week ago about my hd2 getting water in it and drying it out with silica gel. It's been a week and the water has dried out about 95% and looks pretty good. I do have a question though (if anybody has any ideas or insights, that would be awesome)...
The screen is looking good but when I load Opera or YouTube (any screen really that is mostly white) I can see light brown striations in the bottom right corner. Could this be water residue? The "water" was actually solution from Invisible Shield so there are probably other things in the solution besides water. Is it some sort of dried out residue that is causing the striations, or is my screen just partially damaged/discolored?
I read that soaking the phone in alcohol will clear out water/residue from water and was wondering if it will work? Anybody who has done it before? Does anybody know if it will "wash out" the residue causing the striations? Thanks in advance. I'd really appreciate any insight!

Yep. Alcohol got it off but now there's more residue elsewhere -.-
I'm going to open it up in a few days when the repair kit comes thru the mail. Oh my...hopefully I won't kill the phone completely.

I dropped my Kaiser in the bathtub (thanks to my overzealous 2yo tossing it at me when it rang) and immediately pulled the battery. I let it sit out overnight in a bed of rice, but the keyboard still had some moisture in it the next day.
I have some dielectric fluid for various projects and decided to give that a shot, since water will float to the surface of any mineral oil-based fluid. It sat there for about an hour.
When I finally got the nerve to turn it on, the screen was very dark and didn't make it past the first bootscreen. I pulled out the keyboard to find that the fluid had stripped the adhesive from the keyboard lining. Now the phone is another toy for my child
Just Curious: How did the fluid get inside the phone? Did you not follow Zagg's directions?

there was fluid on the counter and I didn't realize it. It seeped in from the back where there were gaps. I used to have an iPhone and that never happened cuz there were no gaps for water to get in especially in such little amounts. I've put 3 zaggs on 3 different iDevices in the exact same manner and they never got water inside.
hello people.
i'm a little late for an answer but the same happened to me just today. i removed the first protector and installed the second one and the glass cleaner (i didnt use water, just a glass cleaner that is self drying) got under the screen. i see a big shade that is getting bigger by the hour and i dont know why. i see it very clearly when the screen is showing something white. I' m hopping for now that it will go away.
Also i would like to say that there are some spray canister for that job. to remove the moister from electronic devices. the local dealer of nch corporation demonstrated me once a product like that and i was very sattisfied. So if the moister persist i will try that.
The problem with LCD screens is all the layers of material inside them, once you get moisture, residue, dirt inside an LCD its likely wrecked forever. I mean the LCD will still work but you'll probably never get the discolorations to go away. I have pulled apart a few backlit LCDs myself. Typically you have the LCD panel on top, 2 light diffusing layers, a "lightpipe" that takes the light from LEDs or CCFL tube at the edge of the screen and evenly distributes, and then a silver or white layer backing the whole thing.
Your only true chance to restore the LCD to original, would be to completely disassemble it, separating all the layers and then cleaning each layer back and front with a good cleaner, lint free microfiber cloth, and then try to reassemble the whole thing without getting fingerprints and dust from the air inside. It can be done. but its really not worth it when you can just pickup a LCD module off ebay.

[Q] Cracked screen -> fast battery drain now

I cracked my screen pretty badly this weekend and am planning on ordering the replacement parts this week (debating the just glass or the new glass/LCD options). But I've noticed since then(last 2 days) the battery has drained pretty fast. Normally I get 2 days from a charge, today I pulled the phone off the cord at 8am and now at 3pm I got a pop-up saying <10%. The phone has only sat on the desk. No calls, no emails, no text, no web surfing.
Maybe the screen is getting mixed signals, being cracked and all.
Any ideas?

I am not really knowledgable about the exact interworkings of the HD2's internal hardware. But I do think it would be a pretty fair assumption that the cracked screen could be the cause of the sudden battery drain. You know your HD2 better than anybody else would as far as daily functionality of your HD2. So if it was not having a battery drain before you cracked the screen. And now you do after and this is the singular change in the state of the HD2 be it hardware wise or software wise. Then logic would say that is it.
Have you thought any about it might not just be the screen that is cracked. What about the internals. How hard did it hit, and how hard was the object the phone hit????
One last thing, be nice to your HD2, it is nice to you. ha ha ha....... But really take it easy on the hardware.
I trimmed the tape on it down to only covering the glass (finger protection mostly) and got it off the edges and out from around the back. This seemed to really help. I've noticed from the beginning of owning this phone that there are some sensitive spots on the sides that when pressure is applied the phone acts like a button was pressed etc. So I must have been causing this. Even with the screen off it was still reading a button push and having to process this action, using power.
I need to find a hard shell for the phone. The rubber thing that came with it is useless as it sticks in your pocket, I need smooth hard plastic I guess. The phone slipped out of my hand as I was getting out of the car and landed face down. Pure accident.

I too have notice the same thing about my HD2 that ertain areas around the edge are sensative, like you said almost like you were pressing abutton of some sort. I am glad you figured something out that helps stop the battery drain. I know that can be agrevating as hell.
If you have a T-Mobile HD2 like I do you could try the Body Glove. I have one on mine, it is a two piece hard plastic cover you HD2 slides up in. ig has a pull out kickstand on the back also, I really like it. It has help protect my HD2 several times when I accidently dropped it out of my hand. I do warn you though after having it on your HD2 for awhile it will make to little scuff marks of the clear coat on your battery cover. Also I have notice I have to make sure I have a ferm grip on it when I pick it up cause the plastic cover is a little slick not like when gou have the rubber case on it. I attached two photos of the cover, oh and you can buy it from T-mobile store or from the T-Mobile website. I suggest website it is cheaper there.

Copter screen protector fail

Got myself a DHD today and a copter for the screen!
But after I carefully attached it to the screen and turned the phone on for the first time, i saw the copter-fluid slowly running over the INSIDE of the screen.
Somehow it had seeped into the tiny cracks around the screen and gotten to the LCD.
The screen has a odd "3d" pattern with dots all over it now and i am quite devastated to see my new phone in this condition :/
I placed it in a small sealed box containing cat-litter and placed the box on a warm place (this was 7 hours ago), but i am not seeing any improvements.
Is the cat-litter enough to remove the water or is there another way to get rid of it. OR am i f*ed?
Hmm, are you sure you actually have a problem?
All DHDs have a "dot pattern", its a regular matrix of dots that is visible at some angles, it is normal.
It's hard to understand exactly what you mean without pictures, but having applied many of the protectors I really dont think you aught to panic
The spots are 3mm large and look a bit like droplets of water (randomly scattered across the screen), there is also "shady" parts around the edge of the screen. And these shades was what i saw growing when I turned on the phone.
I took the phone to the store where I got it and they advised me to get an insurance just in case the fluid screws anything more in the phone.
I will fix some photos tomorrow that shows what it looks like.
This is what it looks like, it is very visible from this angle.
The spot's have actually grown during the night
I keep the phone in a sealed box with a bag of calcium chloride (from a dehumidifier).
Wow. I honestly think you could be able to claim this on the DHD warranty.
I work in an electronics shop, and I apply Copters to peoples' phones regularly, generously using the spray liquid; it really flows all over the place, and I've never ever seen it get under a screen.
You should contact HTC and maybe complain about the lack of proper isolation of the display.
When I put a copter on my DHD the liquid was everywhere, I just mopped it up, sprayed the edges with compressed air and all was well.
I will do that if i dont see any improvements by tomorrow, i turned it on a few minutes ago and saw that the dark spots has grown a bit more.
Do anyone know where the moisture indicators is in the phone?
I found the one at the battery, but it was white.
Update:
The spots have grown even more
Thats why we all shouldnt use protectors that require any fluid to put them on the screen. It looks like digitizer and lcd werent stick properly to each other (as they are sticked) and fluid got into free spaces between layers. Electric toys and fluids based on water dont like each other % fluid are much better for such operations if u realy want to use any fluid to get bubbles off ...
And one more thing about pictures... Ure saing that spots ar growing ... i think they are not growing but fluid is getting off slowly from there and they are rest of it. At start there were only fluid on whole lcd now during getting off it stays only in some places that looks like spots. Leave it for a longer while and they should dissapear (dry completely)

Rather than trying cat litter or rice, by some silica gel, you can get some from eBay, delivered next day.
Seal the phone in a small air tight container, packed with the silica gel and put in a warm place ~30c
If drying is going to help, that will get it dried quickly and thoroughly.
You may have issues with solute residue but good luck!
Thanks for the answers, i have put the phone on top of a bag of calcium chloride (the stuff that is used to dehumidify an entire room).
The spots grow faster when placed with the bag, so the water is probably getting sucked out as you said
Any news? Has it gotten any better?
Well, the spots keep on growing but at least the water is reacting to the calcium chloride.
For some reason it has grown a lot in the lower right part of the screen.

I would just send it in for warranty. Something looks fishy. Perhaps the courier dropped it in a pond accidentally?

I dont think the warranty will cover this, since it is probably my fault for not covering up every little gap or crevice on the phone before placing the screen "protection"
Update: the grey "cloud" is slowly covering the lower part of the screen. Something is clearly happening, for better or for worse is the question. :S
It might end up covering the whole screen then you won't even notice it.

Half the screen is now grey, at least the spots are less visible ^^
Do you think i can use the phone in the meantime, or should I wait until it is completely dry?
My fingers are itching
Hmm, checked the oven, it can go as low as 35 degrees celcius.
Is that too hot for the phone?
35*c is fine, but you must be careful that the oven is indeed at that temperature!
You shouldn't really be using it (or even have the battery in) whilst it is wet, so i would try and avoid it if i were you
