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.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.
Assuming... -
All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

Problem: I need to purchase a mosfet chip from board 820-02100 M1 Pro, that is supposed to be Q5820 but according to Digikey, the schematic diagram I sent them, neither are relevant to the actual mosfet specification I sent them. I just basically need to find this mosfet to purchase, I cannot find it anywhere and am hoping someone could point me in the right direction without have to purchase this entire allusive board. Already checked with Digikey, Mouser, Aliexpress, eBay. Any suggestions?
Mosfet specs are as follows:

Hello, I have a basic power board (from DSLR camera), this board convert 12v in some other voltages (there is no charging chip). This board is disconnected to other, so it feed nothing, the outputs should be open lines.
When I plug the battery (12v), I measure a weird behavior…
I found a mosfet , with 12v at source and gate, and the voltage decrease very slowly at drain : 8v… 7v… 6v… I measured with meter source-drain : 45KOhms, so can I deduce surely the mosfet has a leak (and it is dead) pls ?
The mosfet datasheet, but it's basic one.

Hi There,
This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.
After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

TV Model - LG OLED77G1PUA
Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...
