Hey guys so here is what i got going on. When plugged in you hear a click then the backlight comes on for about a second then shuts off with another click. You can then hit the power button again and the process repeats itself. Where do i start in diagnosing. No swollen caps on any of the boards. Any help is appreciated. Thanks!!

Hello,
I bought a SH Philips 55OLED804/12 TV with known defect in an attempt to repair it for personal use.
The symptoms when bought: Philips logo appears then tv turns off
Things tried so far:
1. Powering it on: Philips logo shows on the screen, sometimes with some minor artefacts then shuts down. Red status led flickers rapidly into two batches then repeats
2. Put it in recovery mode by pressing joystick down then plugging it to mains: The tv shows the logo then shows the android animation along with some minor artefacts on the screen... -

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.

- 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)
