Question about Philips 60PW9363 60" Rear Projection Television
My philip 60pw936317f has a red bow on the left side of the set. Tried to fix with convergence alignment menu option but it won't align on the bad side. I opened the back of the set and there is a box with six knobs where you can adjust the projectors. I started adjusting these when I felt some wiring next to the box arc very lightly to my arm and all three projectors went off. Now when I turn on my tv the picture shows for 3 seconds and then fades to blue then off.
Lost of high voltage on the vertical amp was caused the bowing. That was a simple tweak. I'm sorry to tell you that the high voltage adjustments are rather precise and have major interaction with each other. The HV circuit is also used to power low voltage circuits to gain efficiency. If one or more are not within spec, the process to recovery will require bench alignment of the various stages. Seek professional help or consider replacing. Good luck
