I have a rear projection that after a power outage the HDMI has a black screen but I can hear sound. After reseting the unit I no longer see the composite inputs. Still black screen with sound on HDMI.
If i switch over to the internal hard drive, I can play the demo video and the picture is great.
I have taken everything appart and inspected the main/dm board and everything is fine, fuses check out and the caps are not bulging.
Does anyone have any idea, could it be anoher board besides the dm/main board?
