Weird screen problem?

I've got an R800x here that has some major screen problems.

As you can see there, half my screen has gone grey. Basically, here is what I know about it.
It's a hardware problem, not a software, because I have restored and flashed multiple ROMs since it happened
If it's the flex cable, it's not the usual issue because sliding the phone open does not help at all
It's not stuck pixels, because they usually don't show up in a pattern like that. And shaking my phone a bit can sometimes make me lose one row of pixels to the grey bars, or gain it back
If I figure any more out about it, I'll post it. But my main question is, what is the problem, and how can I fix it?

Bumpin'

obviously the screen is broke lol so the fix would be replace the screen

What tools am I going to need to do so? I'm going to replace the digitizer as well since it's shattered. (That happened in a separate incident)

Well, i dont really know, but beware, you'll need to unstick LCD from digitalizer (cuz its one piece, but 2in1).. But in most times when unsticking the dig from LCD, you can broke the dig too..

The digitizer and the LCD re two different parts of the phone and they are not sticked together. And, this is a flex cable issue. I've got two Plays here in front of me with almost the same issues. I just can't buy a new flex cable here in my country, 'cause all of them is sold out..

Actually, this isn't a flex cable problem. I know what that looks like, and it's not this. It also doesn't have any of the same symptoms.

[PICS] [DIY] Replacing my Screen

Decided to replace my screen myself since my phone is out of warranty. I bought an OEM Samsung screen (that includes the frame) so that I wouldn't have to mess with glue at all. It was about $150 for the screen.
I also decided to replace the USB port because of charging issues I've been having. The USB part cost about $10, and finally the outer frame / casing (with a new back) ran me about $20. So overall it was almost $200, but I have a new phone again I bought all parts off ebay and so far I'm really satisfied! Everything fits perfectly, and the phone looks flawless again.
I only used this youtube video as a guide, it was all I needed. It was pretty quick too, only took me about 30 minutes or so to do everything.

Mid-operation: had to test to make sure the new screen worked before I put it all together:
After:
Oh yeah, I did this myself because after my screen cracked my warranty was voided. I dropped $150 on the screen because I didn't want to get an off-brand screen of lower quality (or risk anything not fitting). Nothing but OEM Samsung here.
Hope you enjoyed

that looks awesome, it's pretty much a brand new phone now. if you dont mind could you provide the link for the OEM Samsung screen + frame for $150?
thanks

As good as new!
Beamed from my Grouper.

Thinking about this to good job bro

The auction is expired, but just search ebay and you'll find one. Make sure to get the right one (ie: verizon one won't work with a sprint frame, etc).

Sure thing. The screen is great! It's like brand new again. I'm extremely impressed for how smooth it went doing it myself.

Awesome!
My nexus broke on my birthday on the 11th (My friend broke it) .. The phone is with the Service Center, they're saying it'll take about a month to fix it. I can't wait to get a new shiny nexus!

[Q] Second opinion on touch screen problem?

Sadly do not seem to be having a lot of luck recently with my HTC Desire Z.
After looking over topics on this subject and trying most of then including using HtcCalibrate.apk.
Found a screen touch test app and got this result:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
I hope you can see this image.
There are 2 lines 1 towards top of screen and 1 in the middle, where I can not make any contact.
I assume that this means replacement of digitizer/touch screen part?
Just would like second opinion or any more options before I try repair or pay for repair.

I have the same problem in my desire z,the non working area of the screen being the left of the screen and the home key.Also sometime the touch will just stop registering touchs alltogether,or register false touches.If someone knows,before trying to repair it,is it the digitizer,or the ribon that conects the two halfs of the phone?

Almost 100% its the digitizer

I have the same problem in a different area. How much trouble is this to replace? Can I do it myself, or is it technical? How much does the part cost, and where to buy it from?

Sorted
Well when I looked into replacing touch screen part, there is a you tube video you can watch to see how it's done.
Yes it is complex in my eyes but have a look here's link:
http://www.youtube.com/watch?v=b9S7k1OJalM
Cost me £45.00 to get it done locally.
You can get part easy off Ebay if you want to do it yourself.

What's the part called? How to search for it?

Parts
Assuming you have the same fault as my HTC you need replacement digitizer.
Just type "htc desire z replace digitizer" into Ebay.

Is the repair easy for an amateur like me? Or is it delicate and I'd better get a repairman?

I find them very simple to replace but i have done around 10 for the vision and dozens on other phones. I dont think you need to be well versed in electronics repair for a job like this, its mostly screws and common sense.
Id say as long as you have a little patients and are willing to watch youtube videos and do a little research even an amateur should have little worries. There is no soldering or anything else that may be considered technical required.
only thing that may be a little tricky for a novice is separating the digitizer from the bezel, but its still fairly easy. for a little more you can buy it together if your worried, seen it this way on ebay at least.
good luck!

How did you claim it with warranty? And how long did it take? I have a note 2 as well, I replaced the glass. It was perfectly fine before I replaced it. All that was broken was the glass. And once I turned it in on became hazy I can still see but it's really annoying not having good clarity. Any help would be awesome. I posted a few pictures of what the screen looks like at start up.

hate to tell you man but it looks like you left the plastic on the inside. It has 2 pieces on the inside

Ensurion
If everyone is paying the $7.99 a month for the ensurion insurance, they cover loss. You have to pay $50 to get a new/refurbished device. But $50 is still cheaper than replacement cost. In lamens terms take what you want off of your device chuck it and claim a loss.

[Q] Am I worrying about nothing?

I just got this thing yesterday from eBay, refurbished from Asus for $209 (32gb) and one of the first things I noticed was a small protrusion from above the microphone jack. Here's my dilemma, I'm really into my electronics looking perfect although I know over time they will have little problems. But is this something to worry about or me just being anal?
I have the opportunity to get it exchanged but it would take a several days and besides being anal I'm not patient.
Thanks in advance.

Well, it's definitely not something that's supposed to be there - I just checked my tablet and it doesn't have that slight lump. The only thing it might possible interfere with would be headphones, and even then there's a really slim chance. Pop in some headphones and see if they work - if they do, there should be no other problems.

I just tested out the headphone jack and it works just fine. So basically it's just an aesthetic issue at this point.
Is it worth going through an exchange for though? Part of me feels as if it has this problem there is a chance it might have others.

For another device I would tell you to get a new one.
But for this tablet...
If you can't find any other issue (dead pixels, random reboot, touchscreen issues grounded or not, etc) you should keep it. The next one could be OK aesthetically but have other problems.

Thanks man, that's a really good way to look at it. I just need to give it a nickname like "bumpy" and get over my aesthetic analness.

Is there a good way to test if he multi-touch is buggy?

"Yet Another MultiTouch Test" from the play store is a good way to test multi-touch.

If the tablet is in a perfect electrical shape, I would simply keep it. Check the display for dead or stuck pixels, dirt or light bleeding ( though I don´t have anything against it ) and multitouch issues. If the device is usable, I would rather keep it and don´t bother about this dent. The guy who has opened the device before seems to have two left hands though...

its evident that it may have been opened (not sure for what). but as mentioned above, if all works great, no issues at all, just use and enjoy it. other units have issues, and risky to get those to replace a perfectly good one (aside from that bump).
