Trying to repair my dad's tv. When I turn unit on, screen will appear showing emerson, then tv shuts off immediately and I can hear a pop coming from speaker each time it shuts off. Tried turning on 5 to 6 times and same thing happened every time. I searched forums and saw another post with same issue but no resolve. Thanks for any help.

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

- Reseating RAM (removing each stick individually stops boot completely)
- Cleaning up recently applied thermal paste around CPU/GPU and nearby VRM components (issue persists)
