Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

The screen seems to blackout and stay black, but with a flashlight I can see the display.

Hi everyone,
I have a NM-A321 board that is dead, with no power at all.
When I received the laptop, the +5VPMIC line was shorted. Removing the PU3 (ISL95905) solved the short, so I ordered and replaced the ISL.
With the new ISL, the short is gone, but still no voltages at all. I measured the following rails:- +3VALW
- +5VAUX
- 1.2VSUS_PWRGD
- 3VALW_PGD
- 1.05VAUX_PWRGD
Additionally, the ISL95906 (PU3) is not getting any voltage on the VIN rail.
The only place on the board where I find any voltage is on the first MOSFETs, specifically:... -

Hello, the DSLR has heavyly fallen. It is dead : no sign of life and display nothing.
When it worked, it always displayed a card present state on LCD display, even when the battery is empty it display a empty battery symbol.
I found a dead fuse, I replaced it and a mosfet burnt, I changed it and another fuse burned. Nothing burned after. And I can't find any short circuit anywhere, it's weird.
Now, I try to understand how it works.
There is two boards (the little one on pictures has no component) : the first is a « power board » : managing...
