Picked up this tv in non-working condition. On plug, the backlight would come on, and the led would flash about 16 times before cycling. So my initial guess was a fault with the mainboard. However, after holding down the reset button and plugging in power, it actually booted and stayed on. Still no display, but backlights good, and could hear roku sounds when pressing physical/remote buttons. No more cycling.
Next, detached one panel ribbon at a time, and got the respective white half, and banding on the other. Tcon seemed like common / likely culprit and are available cheap. Confirmed...

Oh wow.
As in the other thread I was trying to revive/re-bootstrap an old Apple IIe and wasn't successful reading or writing any disk. Both drives behave similarly.
Then I was wondering, what about my PC floppy drives? I have a HH 5¼" HD drive and a combo 5¼+3½ drive. I tried formatting the disk that wouldn't work in the Apple and it didn't work in the PC either!
Then I tried a HD 5.25 disk ... it won't even touch the disk either! Just like the Apple DD disk, "Not Ready!"
Weird. Seems the PC drive is having trouble clamping... -

I would like some help with this MacBook if possible. It came in with not turning on and the Magsafe light was off. After inspecting the logicboard i cannot find any liquid damage and also no burnt or shorted components.
took some measurement and i can see i have fluctuation on PP3V3_S2 and also PP5V_S2_MAIN amongst other rails. Using the thermal camera RC282 & RC283 were pulsing, but after removing these it was still the same.
I then did some investigation into why the rails were pulsing and noticed that P5VS2_PWR_EN (comes from U8100) is also doing the same thing.....
