Hi everyone, I have a Nintendo 2DS XL that shows the orange charging light when plugged in, but nothing happens when I press the power button — no blue light, no screen, no sound.
Here's what I've observed:
All ribbon cables are properly connected
Battery is present and in good condition
No reaction even with screens disconnected
There's a visible burn mark / overheating sign on the metal shield, right above the CPU
I’m suspecting an issue with the CPU, PMIC, NAND, or a power... -

Have tried published resets with no help. (unplug for 10, push on-off for 30, push menu and vol +, etc.)
After being plugged in, red light comes on. Push power button and blue light comes on for ~five seconds then goes out. Power button does not turn the unit on a second time - have to unplug/re-plug before power button will try to start with blue light.
No sound, no picture (used flashlight test).
No bulging cap, no burn spots, no burn smells, nothing visual (cold joints/breaks/bugs).

Hi, I am waiting for my uart tool so I can grab an error code and narrow down where my issue is, but I decided to measure capacitors and fuses to insure everything was okay.
The PS5 turns on with a blue light and a beep for 1-2 seconds then turns off. I noticed a grey capacitor measures no voltage on standby or input power. Does this indicate a problem with the capacitor or something down on the line? I’m getting 3.3v on input with the red cap next to the grey one, and 5.2v on input with the red cap further away from the grey cap.
Thank you for any input... -

Hello, I'm new to the group and to trying to repair a LCD TV. During the past few years, I've been collecting/repairing/restoring vintage personal computers (Commodore, Apple II, Atari, TRS-80, Texas Instruments, and Timex Sinclair). This has been my retirement hobby. Now I've gotten interested in trying to repair a LCD TV that I have and used regularly when working on vintage computers.
The LCD I'm working on is a Insignia NS-LCD019. I've downloaded the service manual that I could find, but it must be a different revision since not too many items in the service manual match the TV...
