[Q] Unknown Error please help - myTouch 4G Q&A, Help & Troubleshooting

hello everyone , i have a mytouch 4G that had the good chip and good display , so that has nothing to do with the problem . my actual problem is that i attempted to do a digitizer repair on my own , and it went successfully , i put the phone back together and i turn it on , the phone vibrated and made boot sound but the screen did not light up, it remained black , i opened the phone like litterily more than 6 times to try disconnecting and connecting the lcd connector and nothing.
to this day it still doesnt light up at all, and now after trying at it one more time the phone doesnt even boot anymore , i cannot turn it on by power button , and when i connect the charger the light is orange , phone vibrates once , then turns green . this is the most i can get out of my phone .
when i was repairing my phone i used a hair dryer to soften up te adhesive , which is the correct way to do it right ? i put the hair dryer directly to the lcd if that probally done anything . and there is a chance i probally scraped a ribbon thats above the lcd on the front when i tried to pry it out
should i just give up on my phone ? or should i try to get professional help and get ready to chuck up 100 bucks for a repair , i am asking if there is nothing i can do.
p.s. i would realllllly like to avoid buying a lcd , cus it would suck if i spend 20-something bucks on a lcd and just to have find out its something else (since the phone currently wont even boot)

the phone probably won't boot b/c you may have ripped out the flex cable for the power button. i made this mistake myself a couple month ago and it cost me like $20 to get a new one. as for the lcd, i'm not sure. you may have to get a new one

Help! My Repair Made Phone Worse!

Hi all, I was going to sell my HTC touch HD to a mate of mine and due to many scratches on the casing I purchased a new case & chassis. After following a guide on the internet, as I removed the screen I caught a small ribbon cable believed to be the light and pulled it slightly out of the clip. We replaced it and put the phone back together and it looks like we have broken the screen as you turn it on the phone vibrates but we get a small white blob near the end call button. It also appears the phone no longer charges although the amber light appears and you can turn the phone on. I think the phone was working because if you press the buttons the phone vibrates, but now nothing happens. Is my best bet to sell the phone as it is or shall I buy a new screen and attempt another repair? its £38 for a new one and I dont want to waste any more money.
Use a program like MyMobiler to check on your desktop pc that your device is working, and that you are sure the screen is faulty. If you really have broken it then a replacement is your only option.

cheers thats a great idea.
Does anyone know about why I may be getting the charging problem? Is it because the ribbon inside the phone might not be earthed 100% as I removed the tape holding it down

hd2 dark screen

i got a crash i resetted ther phone .
after that phone works but the screen stays verry dark.
as if the backlight is broken.
i can see verry little on screen since its just so dark.
phoen works i can get phone cals etc but i just cant see a thing.
whats the problem . is my screen broken ?
please explain the word "crash".
did it fell down or did just windows crash?
if windows crashed and it didnt fall down, you can call htc or go to the shop where you bought it.
DN41
i got an sms .
then phone stopped working .
the touch screen didnt work anymore and i had to take the battery out.
i put it back in and turned on phone.
phone worked but screen stayed dark , i can see something things on screen but its verry dark.
now i put it on the charger and battery was goin empty verry fast even thoug it was on the charger it didnt seem to recharge .
while in the charger the phone was getting verry hot also . so i cant do a thing now .
edit .
im thinking isnt it just possible that since the battery looks dead, that the screen just isnt getting enough power to be lighter ?
since both problems came at the same time i guess they must be connected in some way .
i mean is it possible that a new battery solves the problem or isnt it worht ordering a new battery ?
CRashed ...from a window
My phone crashed too... Crashed onto a carpetted floor from a window (about 5 feet) while being charged, and landed on the edge of a barbell. What was it doing there u ask? I wanted to get the best 3g reception thats why. I use it as my main modem/router y'see...
Yes i got a really dark screen too, and two vertical bright lights. the screen was alright, no cracks, nothing. but the buttons was dented since it landed on the barbell(which was on the floor ).
Sent to the shop and told me it'll cost me about 170usd to fix the lcd,..and said it's gonna cost another 50 usd to fix the touch screen. Knowing the shop was b.s'ing since i know the lcd could just be the only one affected so i plan to buy just the lcd. did a few practice disassembly, and eventually after the 3rd disassembly and reassembly the screen was completely dark...even if it did lit up, i cant see any image.. so i guess i'll just get the lcd+touch screen. since i dont wanna go through the hassle of soldering the fine connection anyway, i decided to buy the lcd+touchscreen online cositng about 140usd..
well, obviously mine's a hardware problem.. Buy yeah I'd say that the hd2 is sooooooooo fragile, your hd2 problem might be mainboard related.
ps. still waiting for my replacement lcd+touch.. who knows if mine is motherboard related too(since the buttons get hot, but i can still recieve calls+use as a modem)

Click to expand...
Click to collapse
if you can see the screen at all, you might check your backlight settings to make sure they didn't reset to like 10%.
Otherwise, I would take it in to get fixed. Sounds like the backlight died.
Have you hard reset to make sure it isn't a software issue?

[Q] x10i wont turn on

Hi, need some help my girlfriend through my x10 at me and cracked the touchscreen digitizer which i replaced with a genuine one.The thing is when i went to turn it on nothing happened so i charged it for about a day when eventually the red battery led started flashing sometimes but still the phone wont turn on.with more charging and disconnecting the battery etc i got the green led to come and when i turned the phone on i got a short vibration and green led but nothing else.so tried updating with seus and finally it seen my phone and told me my software was up to date so i tried to re-install but kept getting errors so still phone wont turn on and now green led does nothing.so cut a long story short i took apart the phone again and noticed the lcd had a line down the middle which seems like its cracked also.My question now is if the lcd is cracked would that be why the phone wont turn on i would of thought it would have came on but just had colours splurted all over the screen.Oh and just so you know battery is sitting at 3.7v so is well charged,im thginking the motherboard is gone,please advise me what to do next.
did she throw the phone at you coz you wrote her a letter without paragraphs?
lol,can you help me
lol not really
but it does sound like the motherboard is screwed. not sure how the 2nd screen got cracked tho.
Why haven't you taken the phone in yet? is it not on contract?
O.k., I agonised myself throug you post....
PLEASE make your first post easier to read, as there are several non-native english speakers here. (Like me ).
Can you please write something about what happened to the phone?
- Did it work fine before you repaired the touch module?
- Why was the old module defective (Did the phone fall down or did anybody sit on it).
- Is there some waterdamage?
The more information, the better....

Replaced the digitizer, Smartphone only boots when not in housing

Hi guys,
hopefully somebody can help me with the problem I have with my beloved HD2. I've successfully replaced the digitizer within my HD2. My problem is though, that the phone only boots when it's not in its housing. When I take the mainboard out of the phone's housing, the phone boots just like it should. But as soon as I put the mainboard back in, the phone doesn't boot, it only vibrates and then shows a black screen (with the backlight turned on).
Any ideas on this? I'm kinda desparate right now . Any help is highly appreciated.
Thanks in advance
propably bad used screen without scratches! happened same.. just digitizer dont working when in housing..
HD2
HD2 the best of the best
May a bad cable connection be the reason?
Or a slack joint?

[Q] need an expert, i hope this isnt the motherboard

Ok, so my G2 died the other day. Well, it still works great, but the screen went to white fuzz... like what you used to see when the rabbit ears on your Tube TV didnt get any reception. Static fuzz, but thats all it showed when i powered it on.
The phone, that day before it broke, was on the boat and got really hot. Once it cooled down that night this happened.
In my grand fix it fashion, i opened the phone up wrong and ripped the LCD ribbon off the screen. Blah. So I just ordered a new OEM lcd panel/touch digitizer kit from ebay.
Popped that in the phone, and behold, it booted to the LG logo!! then the logo went out. That was that, just a black screen. But the phone still was working, i can hear it boot up and receiving texts.
I tried to boot it a few more times (disconnect the battery, reconnect, boot). The LG logo comes up, then goes out.
I found out if i let the phone sit for 30min or so, it will actually boot just long enough to hit the desktop and it seems fine. But it wont respond to touch at all, then seconds later it goes black again and thats that until I let it cool.
There is nothing else apparently wrong. It just wont respond to touch at all and the screen blanks out soon after boot. Its definitely some chip heating up too much and failing. I see on the main ribbon assembly, the one that connect the LCD to the mainboard, has some chips on it... it reminds me (A LOT!) of the TCON boards on LCD TV's. When those go bad, the TV still works fine but the display is all messed up. So I ordered that assembly and it will be here in a few days... but has anyone seen this before? does that ribbon assembly really ever fail? Again, the motherboard would be the only thing left, but that does still boot and work... I haven't tried connecting it to a TV but i wouldn't be surprised if that works... it just doesnt display anything on the phone's screen.
cable assembly didnt work :/
ordered a motherboard. this will be a practically new phone by the time its working again... if ever...
SUCCESS!!!
New motherboard installed. Finally boots and works properly. Well, it sort of has to, because there wasn't much left to replace! New screen/digitizer, ribbon assembly/charger port, and motherboard!
Just did the manual lollipop update!!!!! I got my phone back!!! screw you crappy 4" backup that i hated!
