Re: Troubleshooting Question


Does the set shut down? If so check the diagnostics by pressing input and menu together for 5 sec. on the front panel. You will get a 2 digit blink code on the LED on the front panel. Count the blinks between pauses. If not, do you have menus or OSD?

The thin curved lines tell me that you likely have a convergence or vertical output failure, possibly both. The convergence output amps and the vertical output amp are powered by the same positive supply IIRC and you likely blew a pico fuse on that supply or one of those circuits is pulling it low.

Other possibilities are a coolant leak which you need to check for very carefully or bad capacitors on one of the low voltage supplies.
