Question about Pioneer PRO-520HD 53" Rear Projection Television
About two weeks ago, my Pioneer Elite PRO-520HD TV's picture would "jump" periodically, like it does when you change aspect ratio modes (Full HD -> Natural Wide -> etc...). The jumping would be accompanied by a popping noise coupled into the set's integrated speakers.
Last weekend, the TV would not come out of standby. When I pulled the plug, and plugged it back in, the TV comes out of standby, powers up and then shuts down again - back into standby. Some investigating (and purchase of the service manual) revealed that the internal protection circuits have kicked in - the Power Down LED is now lit on the Power Supply Assy. I'm not sure how to proceed. The service manual is written in Jenglish. It seems to be pointing to the need to replace the SIGNAL Assy, but at almost $500 for a replacement board, I want to make sure that's in fact what I need to replace. Any ideas how to verify that's in fact what is bad?
Thanks in advance! Tim
It is most likely just solder connections on your power supply. If the only diag LED that lights is on the supply, then thats usually the case. You can unplug the set and remove the supply to fix it with a little soldering. You have to remove the metal board supporter from the bottom of the board and solder quite a few connections. Look for cracked connections on the power connectors to the rest of the set, and also connections on the main transformer. If you need soldering experience, get a kit at radio shack and build a little project to get some practice.
