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.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't

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

Hello everyone,
I'm trying to repair the power supply board from a Lenovo ThinkVision P40w-20 monitor. The board is labeled with the following markings:
- Main PCB code: ILPI-422 VA (dated 2021/11/24)
The monitor is completely dead, no power LED or backlight. Upon inspection, I found a few components that appear damaged, particularly some resistors that are burned and unreadable.
Attached is a high-resolution photo of the power supply board.
Does anyone have a schematic, boardview, or similar power supply that can help identify the... -
Hello friends,
I have this laptop AMD Platform starting & not posting, fan spinning.
When i press power button, the board get almost immediatly 0.5A ~ and board get stuck at 0.5A with power button led blinking indefinitly.
If i stop the computer (pressing 5s power button), board stop and when i restart i get approx 0.37A ~ and
I try to reflash the bios with no luck, same result, and i try disabling onboard ram (i remove resistors accordling schematic), no more progress.
