sounds like a mainboard issue.

Yes definitely a main board looks like main chip has failure due to bad bga soldering.

Hit it with a hairdryer for a few minutes, then see if it comes on for a bit.

No bad soldering in this case!! Use immagination.. bad lamps means overvoltage , then also overvoltage to the main board! check the standby software memory first.. is there a spi flash? rewrite it..
