Question about Pioneer SD-P50A5-K 50" Rear Projection Television

2 Answers

Pioneer SD-P40 Hello all,With all the power outages and so forth my Pioneer SD-P40 has decided not to power up completely. I have the green power light but no sound or picture. I have done the easy stuff like check fuses and a the TP's with given voltages, all read good on my DVM but it is almost impossible to find any schematics or photofacts for this TV. Any suggestions? Thanks, Bryan

Pioneer sd-533hd5, STKs changed, getting blue screen but not pict

Did you have double image before changing the stk's ? If not then there was no need to change them.. Pioneers are known for bad solder connections especially in the power supply section.. suggest checking that when you changed the stk's that there are no solder bridges between the pins of either stk ICs

Have you tried to do set the convergence with a pattern on the screen? Some tv's have the pattern built right into the setup. Others do it auto just by pushing a button. Adjusting the pattern on one side of the screen may affect the other side, depending on how far out of whack it is.

Magnets (speakers) near by will play havoc with convergence.
