Product: HP 1155 All In One
My HP 1155 will not boot:
Power light is ON.
HD Light is NOT On Tried the troubleshooting steps online and still not work.
It is either the motherboard or the display. Maybe the backlight board.
All cables are tight
Cannot get on to see OS-probably Windows 8/10
Customer said it just stopped after turning off power the night before
Can anyone tell me how to determine which one is bad so I can purchase it and replace it?
