[Q] Replacing Evo screen with a HD2 screen - EVO 4G Q&A, Help & Troubleshooting

My girlfriend has a Evo 4g that sumhow got wet, she swears water was never around it but she'sa girl so wut do I no... Anyways, we put it in rice for 2 days then took it out and haven't used it for about a week, screen still doesn't work, everything else perfectly fine. So my brother has a old hd2 wit a broken digitizer but the screen works, would it be possible to replace my girlfriends evo screen with his hd2 screen? I'm pretty sure they came out round the same time and they are the same size.. jus wanted to ask sum pros before I go messin up a whole fone for no reason
Thanks!

Maybe, if they both have the same size/type of ribbon connector.

Yeah I had that Thot after I took it apart.. if the screen only has 2 ribbons would that make it not work?

That's probably your problem. If the HD2 screen has two ribbon connectors, then it needs both of them to work. Which the EVO only has one connector for the digitizer.

U cannot do that it will not end up good pm me with any other questions

Re Blue Angel Touch Screen
I also did the same with mine two weeks ago (Cracked the screen)
Took out the left hand screw of my XDA 2s and then took it back to O2 shop and made out that it was because the screw fell out that the screen broke I know its a bit naughty but I got mine replaced for a new one
Naughty indeed. i like the way you think though. the prob is i kinda know the fella in the shop. does it have to be the shop that i bought it in.?
craked screen
Dont think it matters as long as its a o2 shop (in my case)
I just took it to the shop with the warranty 2 weeks ago as i had droped the XDA i took out the top left hand screw and said because the screw was loose it made the screen crack when i touched it with the stylus.
They replaced it under the warranty for a nice brand new one.
Now got 2 batteries and 2 chargers.
mabye i'll just do that. i was gonna get a screen of e-bay. but your way sounds better
thanks
No probs good luck but remember that it is possiable that this could happen (Screw coming out screen cracks) So dont let O2 fob you off and say it is not coverd by the warranty because the situation can happen.
mine is cracked too, but i have to get one off ebay cause it's out of warranty
(only £20 though so not as bad as when i broke the actual lcd - that was £90)
Was the screen hard to replace?
the lcd was kinda easy, and that involved removing the touch screen so i guess not (my new touchscreen hasn't arrived yet)
did you get your touch screen ?was it easy to install ?

I replaced my touchscreen (without LCD) by myself. It is not very hard. You have to solder 4 small cables. If you can handle the tiny screws and aren't afraid soldering 4 cables onto a 7 mm flatband cable. No Problem.
It is a little bit tricky to open the device because of the slider. The two cables of the slider are just plugged in onto the mainboard, so you can just pull them out with a screwdriver.
Plz help me........

Can you give some hints on how you disassembled the display.

[Q] Could it be my digitizer?

Hi I'm new here and I am very sad because my 3G Slide got wet at the front (even the wet marks at the back and an the battery are not red) and since then my screen its not responseve at all in several sectors, in others wasnt at first but now its working, i would like to ask if some knows if this can be fixed with just time or my digitizer is already broken and i need a new one, i think the mainboard is ok because the phone is fully fuctional with the qwerty keyboard and the trackpad thank you
How long ago did it get wet?
My wife dropped her phone in the toilet..none of the water marks changed color but the screen never worked again..she took it back to tmobile and told them she didn't know what happened..they said they do instore tradins now for the slide for nonfunctioning phones and gave her a brand new one..

Oh, so its ok now? Haha. Well not that same phone, but you've got a replacement, right?
I was gonna suggest that rice thing, but I don't even know if that would do anything.

Is krazy glue conductive or something?

Hey guys,
I tried replacing my DINC digitizer again and everything went smooth until I booted the phone up. The middle of the touch screen doesnt work very well. I checked the cable to see if it was loose multiple times but that didn't work.
So I took the whole thing apart again and looked at it closely and realized the Krazy glue I applied was applied on the side roughly where the problem lies....
Is it possible it is messing with it so that it is detecting a touch there or something? I used krazy glue on there because I thought it would be like plastic.
Or is this just impossible and the digitizer I ordered is defective? It works besides the middle section of the screen.
on the contrary superglue is insulative which could also be the issue since the digitizer needs to be grounded not sure what it is like under the digitizer but is the area it gets glued to kinda metallic if so that could be your issue if not then it could be a bad digitizer i dont think i would have not used superglue i would have used double stick tape or something like that... or hell with how my case i have on mine is designed i would not have used any adhesive just left my case to hold it onto my phone incase it ever got broke again...
Hmm, ah so perhaps it is just not allowing that part of the screen to be sensed.
In any case, I replaced my "new" digitizer with the old one that is slightly cracked for now. I used krazy glue and it worked perfect this time, but then again i was careful with the application.
I will clean off the "new" and try one more time, but I suspect now that the "old" is working so good that it was in fact a defective one.
sorry to thread jack, but since there is discussion already started, I have an slcd dinc, can I directly swap the amoled screen into it? Would you guys happen to know?

it will not work. the board requires different drivers and i think a different power output. (i could be wrong) but its like if you bought a plasma tv and swapped for an lcd panel.
kind of figured that. thanks makes sense.

Evo screen / digitizer problem?

My wife somehow got baby oil in her Evo. It seeped into the LCD so I got a replacement. I put in the new LCD and now the screen has distorting green lines. If I peel back the digitizer the screen looks normal. I figure that there also must be some damage in the digitizer, but wanted a second opinion before I purchased more parts. I have attached an image of the phone, sorry about the quality, my wife has my Evo currently and I took the pic with my Xoom.
Yup looks like a digitizer issue.

Thanks for the help, I just wanted to check before I ordered another part.
No problem. I would recommended getting the whole front section. The digitizer is very finicky and can be damaged easily.

Dropped Galaxy S3 in Bathwater

Hey everyone, so my buddy recently dropped his Galaxy S3 in bath water. He ended up buying a new phone thinking the phone was dead but he turned it on a few days later and it worked. Everything works EXCEPT the touch buttons next to the home button. I bought the phone off of him for $150 thinking I can fix it but as I research video and threads online.. it seems much harder than I thought. I know that soaking the phone in 99% isopropyl alcohol can fix a lot of water damage problems but I'm not sure if I should soak the motherboard in it as it's working fine other than the touch sensor buttons. Should I dip only a part of the front frame (where the touch sensors are) in isopropyl alcohol stopping right below where the LCD screen starts?
I'd like to change the frame as well since there are some scratches here and there along with the home button. It works but the button is scratched up a bit.
Do you guys have any advice for me? The phone is currently disassembled btw if that helps.
Could always download lmt launcher and not worry about it?

Or modify your build.prop to add capacitive buttons

Just use a ROM that has navbar settings and dont worry about the buttons. I dropped my old optimus t in water and yea it comes back to life , but the uncertainty of how long it will work is terrible. A few weeks after it happend phone screen flickering and it just died.
Best thing to have done was pull the battery and let it dry for two or three days

Lots of ways to just bypass the buttons all together. Like thwy all said use a custom ROM and nav bar. Just let it dry and leave it be. Good luck.
Oh and give lmt launcher a shot too

I would definitely research cleaning it properly.
The water residue will eventually crust up and cause connection issues or shorts.

What do you think is a good way to clean it? Dip the main board in isopropyl alcohol?
I am a tech junky, the first thing I would do is take it 100% apart and clean every inch on the inside. Eventually the stuff inside of that phone will turn cruddy from the bath water. $150 for a SGSIII is a hella good deal, rip it apart and give it a good cleaning.
Thanks yeah I thought it was a great deal, I could've asked him to drop it less but I felt bad since he was my friend. Phone is brand spanking new and only used for 2 months.
I'm thinking about buying a new whole front piece (LCD, digitizer, frame) though.. what do you guys think? I can get it online for $230ish and not sure how much I can get for my existing front piece.

I would try to fix it before going for a new front piece. Getting that new front piece + the 150$ you already paid = the price of a brand new S3 on ebay.
If it's himidity keeping them from working, leaving the phone in a seeled bag of rice for a couple days can fix it.
If you have the $$$ laying around to do it I would say go ahead. It may help the resell value down the road. I can't stand this phone naked, it feels like a big wet bar of soap in my hands. I would preserve the $$$ spent and put it in an Otterbox Commuter.
I was thinking about making back the money by selling the original piece. Not sure how much I can get for that though. The only thing holding me back is replacing the silver bezel around the LCD. You have to remove everything and swap it over including LCD, glass, buttons, etc. Sounds like a big risk for someone like who who has never done this type of work before.

Well if getting someone to do it for you doesn't cost much, could be something to look into.
Yeah currently looking for someone to do that for me. Not sure where to look... all these cell phone repair places want to replace the whole piece PLUS they keep your LCD for "recycling" which means they'll take my LCD, repair it and sell it to the next sucker for $200 something.
I'm in NYC btw.. so by any chance any of you know someone in the area who has experience doing this, please let me know. Thanks!

Soaking it in 99% isopropyl alcohol right now. gave the mainboard a scrub down with a toothbrush about 1.5 hrs in. Also scrubbed the back of the touch screen, whichever resistors and chips I saw.
Fingers crossed.
Quick question.. how long should I let the parts dry after taking it out of the alcohol? It seems like alcohol evaporates pretty quick but the smell of it stays.
