Is the panel yes. Not sure it's fixable. Look through this thread it may be similar enough to help you, not the same model as his was 70nu6900 I believe.

Here's a pretty good dive into it, pretty good explanation of how the shorts can be about anywhere on those lines and results can vary widely, if you check the last comment there's a link to his continue video of it: https://www.youtube.com/watch?v=7HMGyt1nNgYComment

Hello everybody, I could use some help on this one... It's got me guessing...
I took pictures of all the boards and the pin out of the connector on the power supply that goes to the main board... I measured all the pins in relation to chassis ground, here are the result.
(B13v)1. 12.7 volts cycling (Vamp) 2. 12.7 volts cycling
(B13v)3. 12.7 volts cycling (PWM5) 4. 1.0 volts cycling
(OD_LE)5. 2.8 volts cycling (PWM4) 6. 0.9 volts cycling
(OD_ON)7. 2.8 volts cycling (PWM3) 8. 0.9 volts cycling
9. ground (PWM2) 10. 0.9 volts cycling... -
Hi all
There's two other threads about this monitor with seemingly the same problem. The problem was resolved in one case by replacing the entire PSU board and in the second one by replacing an unknown IC.

The first one has pictures of the pcbs and I noticed that there's one IC and assorted caps not populated on mine (but the PCB itself looks identical) so I thought that'd warrant a new thread.
It's my dad's old monitor. He... -
Hello everyone!
Recently I've noticed that some ShopJimmy backlight strips don't have double-sided tape installed upon them when an application calls for it, and I must purchase the tape separately. In a recent chat conversation with a customer service agent I told them if this tape wasn't applied when it was called for I would begin to consider ordering my backlight strips elsewhere. It looks like this time may have come.
I recently got a TCL 65S4 with bad backlights. After looking at the SJ listing here: https://www.shopjimmy.com/tcl-jl-d65...365as-m-led-ba...Yes0%1All backlight strips are the same quality0%1No0%0 -
Hi all,
I got a 16inch MacBook Pro showing 5v and 0,3a on the left ports and right side has one power cycling and one showing nothing. The one cycling shows 30c under thermal camera. Surrounding components show no corrosion or any shorts.
Any ideas what to check next? The whole board looks clean compared to the other A2141s i saw.... -
Hi. Working on an A2141 that is power cycling. Powers up fine (20V @ 3.1A peak) -> fan spins ok and then at a higher speed (after we removed the trackpad so the sensors are missing) -> chimes ok but after the high fan spin -> power cycles and repeats this loop. We did manage to DFU the unit with revive mode (4/4 steps completed ok) -> resulted in a brief padlock graphic before power cycling. Unable to toggle the keycaps led since the boot does not reach this far of the cycle.
Q: Does the DFU process validate that the nand flash is OK ? We do not wish to restore this board...
