SER5 5560U no video output

beelink1234

The system worked fine for almost 3 months but it just don't put out any video signal anymore.
After rebooting by recycling power, it just stays in high fan noise mode without any video signal.
Power button doesn't work at all so I had to pull out and put in power cable whenever I need to reboot.
I tried to factory-reset by pressing pinhole button after turning off, but it didn't help at all.
I sent an email to beelink support team but there's no response.
Does anyone here had similar issue and have a recommendation?

Hello,
Sorry for your trouble.
Pls check your email.

I tried everything mentioned in the email but didn't help.
I re-seated RAM and SSD, cleaned up RAM, tried only one RAM by turns, etc.
Strange thing is, power button do nothing. As soon as I connect power code, the fan spins at high speed and no video signal.
To turn it off, I have to disconnect power codes.
I think there's something wrong with mother board.
Can I get replacement as warranty service? I'm using my old laptop now. :(
