Hello,
This is my first post. Long story short... This motherboard run the Touch cash register at my friends restaurant. He paid that Touch Cash register a heavy price three years ago.. and that device doesn't start anymore. Of course the reseller said it's out of warranty and offer to replace the device for 2000 USD !
My friend was really unhappy has he had to close for long period due to covid and now that device fail and he doesn't have money to replace it. The device was working... and the next day, no way to boot it, black screen...
So I took a look, it doesn't really looks bad... but I can't fix it by myself. The device is powered by an external power supply. When plugged, I can see 5VSB LED on. When press power button the other led 5V also turn's on and I can hear the HDD starts to spin.. but no image.
Worst case scenario, it could be graphic chip failure ?... I hope it's not. I've disconnected the Touch screen and I've connected VGA monitor but still, nothing. I've removed RAM, CMOS battery, I did the CMOS reset with the jumper, doesn't help. I don't head any "bip" when I power it.
I don't see anything wrong on PCB, no short, no bad smell... I've google it, couldn't find a lot of information on that motherboard. I've search on this forum as well then I decided to post.
If you guys have an idea, I'll be happy to try everything..
Thank you
Sam
