My keyboard lights are completely dead - Mogul, XV6800 General

They would flicker off and sometimes work but with very low lighting. Now (well for awhile) they have been completely dead. Is it possible its just a wire that's loose or is the light really dead? Anything I can do to fix it safely? Lately I have just been using the keyboard in the day and all touchscreen at night.

I bet it is dead. If you have insurance a replacement is free.

Yeah no insurance. Oh well. I just hope this phone holds me until Windows Mobile 7 lol.

[Q] Samsung Galaxy S Vibrant Dies.....Overheated...

I am new here but just wanted to know if anyone else has had issues with their Samsung Vibrant overheating???? I have had this phone for less than 2 months from my carrier and now it is dead and in for repair!! I went to go grab the phone and the screen did not come on; however, the buttons at the bottom were lit up so i tried the buttons on the side of the phone (on/off switch) still nothing. The top half of my phone (not where the battery is) got so hot that it burnt my hand. Then I noticed blue, red, green pixel stars on the screen (which by the way burnt the screen). I don't know if it is a faulty battery/charger? Or what. When I spoke to my carrier, they told me that this is the first they have heard about anything like my case. It has been in the shop for more than 1 month now and I am getting very annoyed..as they gave me a loaner Galaxy to use and I HATE IT!!! Anyone have any suggestions??? I did not game on this phone or anything...
Thanks so much,
Pam
Happened to an HTC Aria I had, and had to get a new replacement to AT&T. The digitizer went (burnt?) out, and since it's a touchscreen only phone it became unusable because I couldn't really do anything on it.
What kind of charger did you use? Especially car charger...
I have never had it on with a car charger. I have heard that one should put the phone on plane mode as the green charge battery light will not come on. From what I hear they are replacing the screen (which they have no choice as it is burnt) as well as the board. Why is it taking soooooooooooo long? I usually have it on WiFi all the time; however, this should not do anything. It makes me mad....I have waited for this phone to come out and when I got it, I thought there was no other...until this happened. I did notice it acting kinda slow and I realize some phones do get warm...but should NEVER get hot enough to burn one's hand!!!!
I'm guessing you didn't OC the phone or anything.
Yea, I keep mine on WiFi basically 80% of the time, but the phone (in stock form) turns that off when the phone sleeps. I have brightness set to auto.
I notice my phone gets very hot when I have it on a car charger, and I'm using a charger from T-Mobile. It doesn't happen when I have it charging from an outlet in the wall through a USB Extended cable.
That's the only time I notice my phone getting hot.
Also, using the phone on WiFi tends to keep the phone cooler than using it on a data connection - I've noticed that for a few phones I've owned.
The overheating issue was also a big problem with HTC HD2s (except those phones would just go into a reboot loop/lock up, instead of burning up ).
No I did not overcharge the phone; however, I do notice that the battery life is almost nil on this phone. Full charge does not last 2 long on the phone and I only use it basically to text my daughters...and a little texam holden lol. But I have noticed with this galaxy (the loaner phone) the battery stays good for 2 - 3 days! Although I really hate this phone so I do not use that much! How would they be able to tell if it is the battery?? From what they have told me, they are only replacing the screen and the board....Well something made it go hot!! Battery or charger...When I took the phone back to Aliant I was going to give them everything including the charger, but they just sent it away with the battery. How do they know it was not the charger?? Getting very frustrated....I have always owned a Samsung phone and have never had any issues until this phone....makes me want to go back....but I do like the Vibrant when it was working....esp the screen.....
Only things I've ever come across that have made a Vibrant overheat is using cheap non-oem extended batteries, overclocking the CPU / GPU or leaving it a car in a 120+ climate then expecting to make heavy of use it without allowing it to cool down first.
I have never replaced the battery...it is brand new (less than 2 months old)....Thank god I had insurance on it... One would think that it would not take this long to come back from being fixed!!! Have never left in car....don't have to worry about the 120 degrees we are INTO snow now!! LOL... I am disappointed with Samsung. How can they tell what made it go that way?? Battery? Home Charger? They should replace the battery in my opinion as well!!
How often does the Vibrant overheat? Is this a common issue?
not sure.....it only took one time for me that fried the phone...Now they are supposedly replacing the screenh (they have to it burnt an image on it) as well as the board.
I have never heard of this happening with the vibrant. They claim they have not heard of this issue??!! I cannot believe this. I would like to know what caused this. I thought perhaps it was the WiFi being on all the time, but I do not think this is why. I do not game on it....I do not overcharge it (only charge it via home charger when it shows battery getting low - which might i add says it is almost drained at mid day??!)
Seriously, I have never heard of a phone overheating. I mean, sure they get hot when talking on it, but never overheat.
my phone has gotten really hot gaming on it while charging (stock charger and moto cliq charger), but it's never died or even decreased performance from it. even when oc'd.
Mine has gotten warm twice: once, I left Google Maps w/ GPS open when I put the phone in my pocket, and didn't realize it until I felt the heat in my pocket; the other time, I left ScummVM running (which apparently doesn't suspend properly), draining my battery over about two hours, again in my pocket.
Both times the phone was only warm to the touch. Nothing like you've described.
So do you have T-Mobile or Bell? If you have Bell (sounds like you do, I'm 99% positive) this is limited to the Bell i9000m Vibrant and not the T-Mobile T959 Vibrant.

There are threas on T-Mobile's official Vibrant forum about this issue.
My vibrant gets very very hot from time to time. I keep it on a usb hooked up to my computer at work with wifi on all day. Sometimes it will get super hot and not want to charge. I restart the phone and it usually fixes the problem. But its not the battery that gets hot, its for sure the yup part of the phone.

Sounds to me like you had a bad battery...this can cause the battery to overheat while charging. I work in construction and when the batteries on my power tools fail you can cook an egg on them when they are charging.

my phone goes to 120plus with me playing while charging. Why don't they just replace thw phone?

OMG there is a ScummVM emu!!!! BRBBRBRBRBRBRBRB.....
Did u happen to have anytype of case on your vibrant. I notuced when I charge my phone with the case on it got prety hot. Not to where it would burn my hand, but hotter than I really thought my phone should be while charging. So I take the case off when I put it on the charger.

[Q] Hardware Woes

The wife and I got Epics and she promptly lost hers within weeks...
We found it a month later laying at the edge of a parking lot. Figuring I had nothing to lose, I stripped it down, rinsed everything thoroughly in 99% isopropyl alchohol, let it dry and put it back together. Amazingly, everything worked fine, except the battery life seemed really short. Figured the battery was bad so I replaced it with a new Samsung battery and it was better but still not great. One night I got up for a snack and noticed her phone emitting light at the slider seam. Upon testing, I've found that they keyboard light is on continually. As soon as I put a battery in the keyboard backlight comes on and stays on, no matter the timeout I pick. I bought a phone with a cracked lcd and replaced the keyboard flex cable, but no luck.
Any further suggestions?
why not just switch the screen with the other phone and let her use that one? Personally Idk.. Hopefully someone can help..
I actually have two dead phones for parts, but neither has the CPU assembly. I tried tearing them apart and switching various parts around between them and I also reflashed it to the stock ROM. It looks like the problem is in the CPU assembly. Wherever that part goes, the problem persists. If I could figure out where the light is, maybe I could just disable it physically.
I would try switching out the wife for losing the phone. Lol

There was a little contention about the matter. However, if you met her, you might rethink. I married up, way up. Luckeee!

HD2 killed itself

So this morning was casually playing bubble jump on WP7 and all of the sudden backlight went off on lcd and the camera flash started going rampant.
hardware buttons wont work and a distinct sizzling sound and a giant pop then came from it before it became completely inoperable.
i left it for a day and the screen turns on but no light and the battery is still amazingly working.
any ideas what the problem might be, I've sent it back now just curios on people's thoughts.
to not confuse anyone it poped again which then made the device inoperable, forgot to mention that *hits head*

suicide !! domestic violence !!
its the HTC auto destruct sequence. It has detected that you have enough money saved up for a new phone, has reported this fact to HTC and they have sent the kill signal. You should start recieving phone ad emails from them any time soon.
lol I would never hurt my beloved HD2 i love it too much.
and im broke i dont have enough money for a cup of tea now days lol
bbbbbbbbbbbbbbbbbibibibi

Maybe you were pushing the GPU aspect of the Snapdragon SOC too much.
i haven't a clue didnt think bubble jump was a demanding game, and i have a job, but ive used all my money on car insurance lol
If you can get to the bootloader (even if you can not see the screen) task 29 and reflash original Win 6.5 ROM. By doing that you can eliminate software and, if you have warranty or insurance, exercise that.
I could not possibly suggest that now is a time to get insurance and, having waited a significant time period, drop the HD2 from a great height.

hey, couldn't boot in to spl due to the pop, i think that ultimately killed the whole system as non of my spare batteries work nor does the charger, the insurance i have on it accepted it fine and have told me i should expect a replacement in about a week.
I am very pleased that you have insurance then and will not be without your beloved HD2.
If no charge is a secondary problem then an interesting test was whether or not you could access the bootloader whilst external power is applied - in this Maglr world I believe that you can trickle charge through that method. You probably did that which I think confirmed a major hardware problem (check battery terminal pins though).
I hope it arrives quickly for you.

well from what i could tell the pins were all still in tact and before the pop, the charger worked on it. seemed very odd why it would just do that, but I'm no electrician. thanks for the replys guys =)

Phone won't turn on. Flashes black when pressing power button.

I bought this phone, used, earlier this week. It was on the official GB update. So I downgraded to 2.2 and did the whole permroot and s-off procedure and loaded MIUI on it, which has been splendid the past few days.
But now the phone won't turn on. I replaced the beat screen protector with a new one from ebay, stealth shieldz from Prestige Solutions. It is a liquid solution screen protector. Anyway, I always turned my phones off prior to installation, keeping the battery in. I have never had a problem. But now with my MT4G, it won't turn on. It did turn on by accident and I pulled the battery out until I was finished with installation. Now it won't turn on.
I've read of bad emm (or whatever it is) chips. I read multiple solutions before posting. But what makes mine a different case is that the phone flashes black everytime I push the power button, or when I plug in the charger, sometimes staying black until I pull it out. I don't see any orange leds that indicate the phone may be bricked. Though, at this point, this case seems worse.
Any idea what the issue may be?

Sounds bricked to me. Call HTC and possibly get a replacement for the bad eMMC chip.
It's funny. I went to the tmo store and they told me it was water damaged, using another battery. Plus, they said the water damage indicator on the phone was peeled off. So I go home and file an insurance claim. I now am expecting the refurbished replacement tomorrow.
Tell me why after I make the claim, like right after, the phone starts working? I don't regret making the claim because $130 for factory refurbished beats $180 and up for unknown Craigslist. And this phone is still water damaged and can die at any given moment. Already turned off once.
I am having a similar issue after a 2 foot drop of the phone. No physical damage on the outside but not sure about the internals. is there a way to start troubleshooting this issue and seeing what i can do to repair? I am so lost right now since this is the first major issue I have had iwth this phone. Since I can not get a screen and the boot into recovery via volume down and power is not working I am not sure what ican do.
It is most likely bricked. same thing happened to my girls. She dropped it and bricked..mine just bricked last week out of nowhere to....got replacement now....both had bad hips...new ones has good chip but bad screen

[Help] Dead screen before and after screen replacement

Hey guys, so a couple of weeks ago I dropped my N4 in water for about 10 seconds, as I was attempting to shut it down the screen flickered and it all went dead.
Fine, so after a week taken apart and in rice the battery is screwed, standard stuff, bought an OEM replacement battery, and then it turned on, worked as it should, except the screen was completely dead, no backlight no nothing.
Again fine, I order a non-OEM screen/digitizer/frame assembly, it arrived today and after being god damn sure everything is correctly assembled I power it on to find the screen is still completely off even though the phone is starting up and working normally (I can hear it unlocking, I can receive calls etc)
Is there another component that has to do with the signal to the screen that may have suffered from the water damage?
Bump. Can anyone shed any light on anything else to try?

My guess is you got a bad screen. There's lots of cheap ones out there. See if you can return it

I suppose it's a shame I can't know for sure cause the new one could be faulty, and the old one could be water damaged in some way.

Hang on, I just realised the digitizer works on both screens, I can unlock it and navigate what I remember from my layout just fine, it's just the display on the new one and the old one, surely that means something else is broken on the mainboard perhaps?
