Hi All, I have an LG 50PK550 with the EAX61392501/10 EAY60968801 power supply board. When I turn it on it clicks and shuts off immediately, I have unpluged the power wires to to Zsus and Ysus board and it does the same thing. I have read up and replaced IC301 & d304 and checked the R927 R929 and all 3 fuses on the board and all appear ok. Still does the same, shuts off immediately with or without the z & ysus board hooked up. Any help would be appreciated. Thx

Check for cold solder on the underside of the board, pretty common. -

Have a look at the components in this repair kit and check the parts on your power supply.

This is a weird one, as mentioned below I checked and replaced the below components and put the the board back in and it did the exact same thing. As suggested I removed the board, reinspected and checked the complete board for cold solder joints and none were found. The board was a little dusty (I have seen much much worse) so I gave it a good dusting with a paint and tooth brush and put the board back in. Now the TV stays on now without issues, I have given it two tests for over 8 hours each. Is it possible there was some dust shorting out something on the board ??

Hello everyone,
I have a Lenovo V15-IKB that had a damaged motherboard. I replaced it with a motherboard from a Lenovo V15-IIL.
The board powers on, but it shuts down after about 10-15 seconds. This only happens when the internal display (LCD panel) is connected.
Here's what I've tried so far:- When the internal display is disconnected, the laptop works perfectly fine via HDMI.
- The laptop shows an image on the internal display for a few seconds before it shuts down.
- I tried swapping the LCD panel with a known good one.
- I tried swapping the LCD cable

Hello everyone,
I have an ASUS TUF Gaming FX505GD that's powering on, showing the ASUS logo for about 2 seconds with keyboard backlight, then immediately shuts off. After it shuts down, the power button does nothing until I unplug the laptop completely. No fans spin afterward either.
I’ve tried:
- CMOS reset
- Removing the SSD/HDD
- Reseating RAM (removing each stick individually stops boot completely)
- Cleaning up recently applied thermal paste around CPU/GPU and nearby VRM components (issue persists)
