G1 Blank Screen - Backlight Works - G1 General

Has anyone else had this happening with thier G1 - we have seen quite a few of these in already that just get a blank screen. The backlight is lighting up but no video coming to it from main board.
We have swapped the boards and proved they are good - appears to be issues with the cluster-f*ck of video flex cables they are using on these. We have worked on alot of HTC phones - this is by far one of the worst designs we have seen to date.
Also, be very careful as we have gotten more than a few with broken or bent sim slot pins..the geometry of the slot lends itself to inserting on an angle and this is all it takes to bend those pins and render un-usable.

How do you do this?
I think you are trying to provide a recipe for those of us, that want a non-conspicuous reason to exchange our OTA RC30 G1s to get RC29 or earlier ones, that can be rooted, instead of our securely locked up ones.
Please provide more specific details on how to do this.
Maybe T-Mobile will add a more relaxed policy towards allowing full access to the device for those that want it, if too many get exchanged with these symptoms
I, for one, would be happy to participate in a developer program (possibly even if it had a small fee attached) and waive any warranties on the device, in exchange for unrestricted access. Sounds like a clear win for T-Mobile...

It sounds like the video problem is just the way the device was designed, you couldn't replicate it without opening the phone and voiding warranty. For the SIM slot, however, all you have to do is bend a pin and it won't be able to read the SIM card anymore. I doubt a rep at T-Mobile stores would check this, and even if they did, it's a design flaw in the phone. They could try and manually bend it back, but tell them you're worried about it happening again etc.
Edit: For the problem at hand however, you're not getting any power out from the mainboard to the screen? Are you sure? If you aren't, then it wouldn't be a problem with the mainboard, but you said replacing that had no effect.

Sound issues with the Wizard

My dear Wizard has broken. Again. In fact this would be the 5th time. But my supplier, 02, is breathing a breath of relief as I've just moved out of warranty and can't get it replaced again (ironically, the last send-in for repair was two weeks ago, which was in the warranty period.)
Anyway, the problem is this. The headset jack is borked. When headphones are plugged in, all the sound is horribly distorted - it sounds like I'm underwater. This is particularly pronounced for the speech part of the spectrum, leaving my music without lyrics!
This affects all headphones I use with it and isn't software as the speaker works fine. If I apply pressure to the jack pushing it up towards the screen, it can be made to sound ok. So I would guess it's a bad contact or some grime etc that's preventing a good electrical contact (the sound does feel like it's being put through a capacitance filter).
Any ideas how I can make it work again? If not, I'll have to go buy a bluetooth headset, but I'm a little skint right now..
No solution from me, but this might help. You can try checking with O2 regarding your current warranty as you have your phone just fixed 2 weeks ago. Some company will automatically renew the warranty period if the device is being fixed under warranty.
Good idea - but when I called up I asked about this to no avail. Turns out they don't provide a warranty on repair models. Arg.
you could try fixing it yourself, google for 'wizard service manual' there is a copy on another forum which you will have to register for, i don't know if there is one on this site
It might just come to that. I might just try blagging a repair - it seems a little out of order that they won't repair a defective phone they sent me somehow. Besides, if I have a phone that works, I can make calls and generate them revenue! But... if that fails, out come the screwdrivers.
Actually, the symptoms suggest to me that it's not broken per se, but rather dirty or similar. The distortion sounds like a capacitor which suggests the jack is being obstructed very close to the contact. Perhaps it needs a clean of a sort...
S*it the bed?
My phone has the same problem. But, i don't think an american carrier would be as understanding as a english carrier about modification, so you might have to do what i am going to do
1. Bribe someone at the T-Mobile store.
2. Bribe My Cousin at the Cingular Store
3. Check E-Bay for a cheep parts phone or a dummy who has a bad description for a phone.

Parts for the Juno

My daughter's Shadow screen went blank... but the backlight was still working leading me to believe that something other than the screen had gone bad. When she gave it to me to look at, I noticed the sliding mechanism felt loose and I could hear something within (crackling like from a stuck or damaged ribbon cable). This further lead me to believe that the screen was probably ok. Following some instructions I found on how to disassemble the device, I was able to take apart the phone. What I found was that two of the four screws that hold the sliding mechanism had worked loose and that the spring had broken in the middle. The loose spring then appeared to have torn away at the edge of the ribbon cable that connected the main PCB to the screen. So, what I need now is a replacement spring for the sliding mechanism and a new ribbon cable. Does anyone know where I could get these? I am hoping that I do not need to purchase a whole sliding mechanism and screen but if I do, than I guess I will do that. Any insight appreciated.
This is the only place that i know of that has Shadow parts and it doesn't look like they have the parts you need.

WHY??
Whats the point of posting unneccessary information?? He obviously cant use it. You could try Ebay. You could try buying a broken Shadow and using the parts.

did you buy this shadow directly fromn t-mobile with renewing your contract or with a new contract?
cause if so the shadow would have been covered under warranty, but if you opened it up and tore any warranty stickers then well you're SOL... i can appreciate the fact that you're trying to do it yourself, but warranty replacements through cell phone companies are no joke and easy to do if its not a problem caused by you
This is why.
I did it just to piss you off.

[Q] Somewhat dead touchscreen?

So my awesome Venue Pro with an already sketchy battery is giving me trouble.
It has only happened lately. I'll turn on the phone from standby in order to, well, use the phone. But 95% of the time, the screen will within a split second go black, showing nothing on it. Funny thing is, every key works and illuminates and you can even interact with the touchscreen as I noticed it made sounds previously when I just started moving my finger along the screen, same with powering it back on when it likes to actually show what's on the screen and it'll be on a totally different app or screen itself.
Because I bought it on eBay, Dell, very ignorantly, is refusing to even deal with me in regards to warranty despite the phone being manufactured this year, so I'm hooped for sending it in at all for repairs.
If the touchscreen technically "works", then what could be the problem?
Thanks for your help, guys.
You might want to google something like "dell ownership transfer." Seems to me there was a way to transfer the original warranty term to another person. If you can get in contact with your ebay seller, he may be able to help you out.
Short of replacement, I say the first thing you should try is opening it up and making sure all the cables are connected internally.

The next step will either be re-flashing the original stock 7.0.7004 rom in hopes that it's a software problem (unlikely if you ask me,) or ordering another DVP off ebay and swapping parts until you have diagnosed the problem.
That's the issue- My eBay dealer didn't actually buy the phone himself. He took them as a donation for his not-for-profit business so the proof of ownership is pretty much MIA.
I'm starting to believe the backlight is failing or something close to that. Possibly due to the slider being used? Not any more often than someone else would use it, though. I looked at the disassembly guide and it's something nearly impossible with my lack of tools or understanding.
I'm pretty much hooped then?
Wow, shady. I bet he took advantage of and offer like this and then just sold the phone for profit.

I can't think of any other ideas personally. Selling it off for parts seems to me like the best course. If you decide to do this, you should wipe your phone with a soft reset as you normally would when selling this phone (in settings > about > more > reset my phone.) If what you're experiencing is a software problem (which, again, I very much doubt) this might fix it. If not, your personal data is gone, and you're ready to sell it.
You may want to let the other forum members weigh in on this, but I don't think there's going to be an easy fix that doesn't involve disassembly.
I have attempted a reset + restore and whatnot, so most likely it would be a disassembly issue then.
The issue with me taking it apart would be that I'd probably do more damage that way lol.

Vivotab RT display problem (vertical Green line)

Hello all,
Sorry for posting here. This is my first Windows device so I don't really know where to turn for help.
All of a sudden there is a 1 pixel wide vertical green line down my screen. What happened? Is there a way to get rid of this? Do I have to send it in somewhere?
Where on the screen is this line? Have you tried restarting the tablet? If you move the mouse onto the line, does the mouse cover it up or does the line go over the pointer?
If it's just a hardware problem (quite possible from the description) you should be able to get a warranty replacement easily. Just set up the new tablet with the same Windows Live account, re-download your apps and mail (you won't be charged again for apps, of course) and you'll be pretty close to where you left off. If you want to be sure all your data is preserved, though, you might want to back it up first (to external storage or to SkyDrive)
Thanks a lot for your reply. I've tried restarting the tablet, and no luck. The line is about 2 inches from the right side. Moving the mouse onto the line, makes the line go over the mouse. Do you think a display driver uninstall/reinstall would help?
If it is a hardware problem, does one just go to ASUS website and find the service phone number and tell them? I just bought it less than a month ago over ebay (Brand New), does it need to be from a normal store? Sorry for all the questions, please just answer whatever you have time for.
Yeah, that's almost guaranteed to be a hardware problem. Given the way the video driver handles the mouse pointer, it's highly likely the pointer would be drawn over the line if was a software glitch. On the other hand, I'd also expect you to be seeing other display corruption and/or video driver crashes in that case. Meanwhile, thesymptom you describe (perfectly vertical line of a single primary color) is actually a common (by the standards of such things) failure mode of LCD screens.
If it was bought brand new, there should have been warranty info included. In any case, I'd suggest getting in touch with Asus, yes. You might need the tablet's serial number or similar, but even if you don't have actual warranty info it should be covered for at least one year unless there's any sign of external physical damage or anything.
Thank you very much for your help. I'll look into the warrantee info.
If the mouse pointer goes under the line, I strongly believe there is a hardware issue. Might not necessarily be the actual display, but could be a cable connection. Either way, it is definitely covered under warranty.
You have one year from the date of purchase, regardless of where it is purchased from. The RMA process usually takes about 14 business days to complete. If you're located in the US and you haven't already called in for an RMA yet, shoot me an e-mail and I'll see if I can set one up for you. I can be reached at [email protected].
If the device is LESS than a month from the reseller, I would actually contact the reseller first to see if you can get a straight-up exchange. I'm not familiar with the particular eBay seller, but most offer a 30 day return period for defective units. Check with them first about an exchange, and if that isn't possible, contact us for a repair.

Two MOTO 4G Play Questions

1. I had to replace the screen a little while ago. All went well except that I damaged my on/off switch button and I need to replace it. I'd also like to replace the volume pushbutton as I bent, but, was able to this one back in shape. The on/off button is held in place by a piece of tape.
I can find replacement buttons for the moto g4, but, the picture looks to be different than what I remember. It is confusing that they have several phones with such a similar name. I also know that many online places don't necessarily even use the correct picture for the specific item on sale to begin with.
I did find an official motorola online forum where they just said that phone has no user repairable parts. I guess I'm a technician/user then and need a replacement part. I never did figure out how to log in to that forum to try to get an answer or even part number.
I managed to damage the part when removing it, but, I imagine they would survive pretty much everything else the might destroy a phone. I haven't really been able to find any listing of very broken ones either.
Any help?
2. I also notice that while playing music via bluetooth to my car stereo that sometimes there is some noise. It sort of sounds like you would get if a potentiometer needs cleaning or the output jack has dirty contacts or gets jostled. Then I remember there are no wires and no potentiometers involved in this situation.
I did read somewhere that this is just a problem with that phone and there is no fix. I get it, it is basically a throw away phone, but, is this really the case. Was this an issue, was their a fix? and/or is there a way to get a replacement that doesn't have this problem or some way to upgrade to another model that doesn't have this issue more affordable?
