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.

I had one blown memory chip (out of 4) the laptop would not work even with a ddr4 module.
I had the on board memory disabled though a custom bios and the laptop was working fine, problem is as soon as the bios get updated I have to do it all over again.
So I need your help on how to disabled the memory at the hardware level, I ve already removed the memory chips and the resistors/capacitors around them but it still won't work without the custom bios.
What else do I need to remove?

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... -
