My projector bulb powers up ok but no sanyo or other logo is displayed, the screen display starts initially yellow then goes to a bright healthy white. However thats all it does, i have tried connecting pc's on both 1 and 2 connections and a video source to the video phone but nothing gets displayed, just total white screen.. but i think its worse than that as i cant even get any menu displayed on screen.?? any ideas
I did find the service manual online and for no picture with any sources it states:
Check signal processing stage and LCD driving stage;
Check RGB S&H signals at test points TPB1, TPG1, TPR1.
Check power supply circuit 15.5V and peripheral circuit.
Check ICs IC501, IC531, IC561, IC401, IC301 and peripheral circuits
Sorry dont know double dutch..
