Question about Pioneer SD-P55A3-K 55" Rear Projection Television
Model SD-P50A3-K Replaced 4 amp 125V fuse 2 times 1st time after 7 years 2nd time 1 week after Picture bowing from sides (sometimes) Colors changing as well (sometimes) Need service manual or schematic to troubleshoot further Looked at some solutions about this problem, but need schematic to identify components Thank You
Problem is on Amp Assy. Resolder transistors and regulators that are mounted to the heat sink and replace both convergence output ICs. Replace the existing STK392-110 ICs with STK392-180 for improved reliability.
