This TV Powers On fine but the screen is cracked pretty bad but you can see it light up, so I was thinking of getting it and parting it out to have all the boards, stand, remote, etc. what do you guys think? is it worth paying $25.

You will probably easily recover the $25 after selling all the parts and boards on EBAY.Never stop learning

original screen was BOE NV156FHM-T07 with On-Cell Touch screen I²C
replaced with what was in my stock, which is IVO R156NWF7 R2 which is also with On-Cell Touch screen I²C
now touch screen works perfectly in UEFI BIOS menu & boot menu. but not working in OS, tried windows & linux too
with original broken screen i can see in device manager touch screen in human interfaces
but with the new screen it's not showing in device manager
is it lenovo blocking it? is it driver missing?
I²C is a headache -
Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".
It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...07-31-2025, 08:37 PM -
Hi,
I am working on a MacBook that came in for a screen replacement. The MacBook powers on and works on the external screen. However, the screen stays black. The replacement screen made no difference. On further investigation, I found small amounts of corrosion.
Please see the attached image.
I ordered a refurbished logicboard, but the problem didn't go away with the old or replacement screen.
Can anyone suggest where to go from here?... -
Hey All,
I have a Sanyo DP5834 that did have an issue with the backlights, but I disassembled the unit and repaired the LED strips by resoldering all of the connectors. Now I've reassembled it and I have backlights and sound, but a grayish screen. I can tap on the screen and see that it's on, but no picture. All voltages seem to be correct on the power board.
Based on the LCD Flat panel TV troubleshooting guide by Bud Martin, I'm thinking the T-Con has failed because I'm getting 12v both into and out of FP1 on the T-Con. Am I on the right track?
Thanks,... -
Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...
