Hey all,
This set was shutting down occasionally with the blue convergence
wandering out of adjustment. Replaced convergence STK 4277 and that
took care of the blue issue. Now, it occasionally "supersizes" the
picture and still shuts down frequently. I see there are at least two
diagnostic LED's, one on the convergence board, and one on the power
board (shown in the schematics as "low voltage detect"). When the TV
is reset after shutdown and restarted, the "low voltage detect" LED
blinks for a split second at the moment the set shuts down. Does this
actually mean voltage is low, or is it a generic indicator that there
is *some* problem on the board? Any guidance on deciphering pioneers
trouble LED's would be appreciated!
