cables that fragil and are mainly a plastic with either a conductive paint or copper cladding is not a repairable thing other then replacement, a few have suggested searching ebay as you can get a replacement screen cheap this may also apply to getting the cable only if it's detachable. but believe me I've tried this and i'm great with surface mount on the PCB direct soldering on the ribbon is possible but the wire type adn tools needed out weigh the cost of the LCD used or new

Well, it is doable, but still messy. Battery is placed UNDER the logic board which means you'll have to take it completely apart. It involves some heating, because both speaker covers are glued on with an adhesive, and only then you can start unscrewing the front. The logic board is connected with a staggering 10 (yes, ten) cables. After you remove the logic board, you'll have to be very careful with removing the battery, since it too is held in place with some adhesive to the back of the LCD screen.
Parts availability on the other hand is a different story. Battery should not be so hard to get I guess... I had to replace the logic board so I had all my berserker skills invested in finding that. Still very hard to get a logic board, at least for any other make than the Verizon. I was lucky to get my hands on with a little help from a friend that works at a HTC service center. Other than that, you'll just have to get creative I'm afraid.
Replacing the motherboard is pretty simple, the hardest part is actually getting to it. Removing the back is a pain in the butt.
You can buy all the parts you need at etradesupply.
The speaker grills come over easily. Then there are 2 phillips and 4 t4/5 screws. Pry it open(Watch some videos for some tips)
For the main motherboard I believe there are 6 ribbon cables attached to the main board, and another 3 attached to the sister board.
If you're technologically inclined and can use a screwdriver you should be fine.

thank you for your reply
my problem was i couldn't find any site selling the m8 motherboard
even etradesupply not have it
Well I'm done with this crap screen I guess the ribbon cable is pinched or cracked somewhere I cant see, I've taken the glass off and inspected the ribbon cables but I cant find it so I'm in need of a new one.
Its the intel sofia quad1 r16. If anyone knows the part # and a place to order from in Canada or the US rather than china that would be awesome :good:
Thank You

Hi,
I tried upgrading my PX3 chip to PX5 and in the process of disassembling the device I noticed the touch screen digitizer connector was not completely intact and I couldn't put it back in one piece. Now my chip is upgraded and I can hear the radio when I start my car but all I'm seeing is a black screen.
Is there anyplace I can buy a replacement for the whole screen (8 inch)? I searched some old threads and came across some links to Aliexpress selling exactly what I need but they weren't working anymore and I couldn't find any sellers right now, or more likely just didn't know where to look.
Any help would be most appreciated, would hate to have spent $90 on the new chip and then have to buy a new head unit to replace the whole damn thing just because one screen connector is broken.
Have you thought about contacting the reseller for spare parts (aftersales service)?
I'm trying to find a 9 inch display digitizer and possibly controller board or driver board or whatever it's called for my head unit. Pictures and all the part number and serial numbers I can find are attached below. Without going into details of fist hit my stereo a couple of times and yeah even though the parts are cheap I'm unable to find one. I got another head unit for like a hundred bucks and then try to see if that one would work but that one doesn't have a separate driver board and it just flat out wasn't working and then I bought another digitizer and display separately that closely mastered I had but I guess because the driver board isn't the same the unit doesn't display anything. The core board gets warm so I can tell that it's actually turning on as well as see the power out of my bench power supply being used but other than that it's not lighting up the display at all there's no click there's no backlight so I'm guessing it's incompatible with that driver board. Can anybody help me find these parts? I'm looking specifically for the display the digitizer the glass that the whole thing the whole display itself. I don't think I need a controller or driver board but just in case I'm going to get one anyway and just replace that in the ribbon cables just everything except for the head unit that has to do with the display. If you have any questions let me know and again pictures are attached for your reference
What did Dasaita suggest when contacted for support and spare parts
Hey,change it to mine with this and work very well.But carreful to the connector.

@DJYoshaBYD I had exactly the same issue with my 9in Dasaita head unit.
There is a known issue with the TFT board that the backlight regulator component (Zener diode - D1) on the TFT board that will overheat and damage the component if you run the display at 100% brightness for extended periods of time. I was able to get Dasaita to provide me a replacement TFT board (that is specifically what you ask them for) and it solved the backlight issue for me.
The TFT board is IMG_20211215_093943.jpg in your set of images
If you still need/want the LCD panel, I have the one that I purchased from Dasaita for $65 (US) which I did not end up using. I would let you have it at my cost + shipping. I have the exact LCD pictured in IMG_20211215_094017.jpg from your images above.
I have listed the LCD display on eBay:

Give me a total for the display. I'd like it expedited. I don't need the board itself the board should be fine I just need the display the digitizer the glass and the ribbons basically the whole display minus the controller board. The board didn't burn out or anything like that fist for some reason landed directly on my stereo and shattered it. LOL. So that's why I need another one. So just the LCD and the digitizer are all I need. So if you can give me a price for just those two things and a price for overnight and like two day like give me a couple of different prices for you know shipping plus like the regular base shipping and we'll go from there
@DJYoshaBYD sent PM.
Sorry to hear that your display got shattered.
The display and digitizer are all in one, just what's shown in the eBay listing is included. I have not even removed the screen protector film from the display.
Will ship it to you in the same packaging that I received it from Dasaita. You can get shipping estimates from eBay as I have also provided shipping box dimensions.
As much as I want to get it dude like I'm going to need like the whole display. Like the LCD the digitizer with the glass and the control board with it and the cables so I mean the whole display as it comes out of the head unit itself so basically from the ribbon all the way to the front of the display I need all that if I'm going to pay you know 80 bucks for it. If you could do 65 flat for the whole thing so 50 and then 15 for shipping I'll pay that. But all I'm seeing in the ad is just the display itself with no digitizer or anything which means I have to spend another 15 or 20 bucks on a digitizer and get a control board of mine's burn out so if you can do all of it for 65 flat I'll do that
I'm offering the display for what I paid Dasaita for it and don't have the ribbon cables, etc. I do have a TFT board that I would be willing to include for the "Buy it Now" price + shipping. When I bought the display from Dasaita, I was wanting the whole front end of the head unit too, but that's what they sent me.
For what I'm offering the item for, I'm not looking to turn a profit. It's just that I sold the vehicle that the head unit was in and now I don't need these parts. Based on what you've indicated, what I am offering would very likely fix your head unit, if only the display glass was shattered.

You're offering $65 with free shipping? With a Buy it Now of $65+shipping I'll throw in the TFT board.
