Question about Pioneer SD-P50A5-K 50" Rear Projection Television
My Pioneer SD-P50A5-K 50 Projection TV has started shutting itself off almost immediately after its turned on. It's fairly old TV, but I'm not sure if it's totallt broken, or if I've missed something and can fix it. Is there anything that can cause this problem, and is there a solution ? I'd be willing to pay for repairs, but how much would that likely be given the problem ? Thanks for any help on this.
This is actually a common problem with this unit and one that Pioneer is aware of... Over time the feed resistors in the convergence circuit change in value and the convergence ICs begin to fail, placing more of a load on the power supply than necessary and stressing components in the SMPS. The fix; Pioneer recommends upgrading the convergence IC's from STK392-110 to STK392-180, change all resistors in the convergence circuit that have changed in value and replace the power supply to repair the unit.

You may need the power supply board resoldered as I had the same problem. The guy listed below can do it for you as I shipped mine from Illinois to him in California... Piece of cake getting the board out of the back and it's not too fraigile... Just pack in bubble wrap and it will be fine. My TV is now working great.
BUT DON'T DELAY AS SOONER LATER TV WILL NOT RESTART..
