hi guys
i have a board here that turnes on but no display(lvds,hdmi,crt)
i try different bios(just find two file to check) ,cpu and ram
i dont have same vga card, but i have N55 card but no result
current usage is natural and post code is "b2" with one bios and "ab" with another bios
kbc is replaced somewhere else but i dont have another to test
what do you think about it?
