Panasonic TH-42PZ80U Television Plug the power to TV the L>E>D> flashes 10 times….pauses then flashes 10 times…keeps repeating. Ive opened the back cover thought I would try blowing out the dust bunnies..no change. So I thought I would order a Main Brd. which I did and it hasn’t arrived yet. So I was doing more research and Ive found the 2 IC’s on 2 separate daughter boards on the Power Supply brd. so I sprayed then with refrigant to freeze them…I did one at a time…and I found one that once I sprayed it..and it was frozen I can power on the TV without any issues…so instead of replacing just that IC and the capistator I thought I would just replace the power board. My concern is on the Power Brd I see a number of NPX702MF-1A and Ive found that part on Ebay but I also see NPX702MF-1 which is a little less expensive…would that brd work?…or what are the differences?
@krc9529 you are absolutely right. The 10 Blink code is most commonly related to a failed PSU. The differences in those power boards may just be related to different version/layouts. Always make sure that the connectors are of the same type and in the same location. There are no good schematics out to do a side by side comparison. I would discuss this with the vendor and purchase it if it has a straight forward return policy.
