Have a 2015 LG 49LF540V that has 1 thin vertical line on right of screen and 1 thin horizontal line across centre of screen, have tried to picture them as best as I can. Have cleaned ribbons and contacts on T con board to no avail, fear it may be a bad LCD panel, any help grately appreciated.

by SysengThis sums up discussion related to Lenovo P14s Gen5 in this thread. Credits go to Sbaro and especially Maxpower3. The locked dump is attached.
The device is based on NM-F871 motherboard with Nuvoton NPCK397 series controller. The motherboard also contains three BIOS chips: two different Winbond chips for main BIOS and external EC flash, and also a Gigadevice chip which purpose I do not know. The password information is contained directly in controller and thus can be manipulated by reprogramming it, so reprogramming BIOS chips is technically not required, however you may wish to make...-

I started on the ACER:
Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.
I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap... -
by DrvLikHellHello again! I have come back for some wisdom and hopefully for some guidance with this problem I'm having. The TV is a 4k 55" Sharp LC-55p6050u and the problem is every other line of the bottom 32 lines flickers out, comes mostly back, then flickers out again, and repeats this continually. The lines on the bottom right of the screen go out completely while the lines on the bottom left are affected so slightly that it's almost impossible to see it. There is a gradual gradient from appearing almost perfectly fine on the bottom left, to an obvious problem on the bottom right.
