Panasonic TH-50PHD3 Plasma

  • I have a Panasonic TH-50PHD3 Plasma screen. When it is turned on the fans turn on and then it won't complete the power on sequence. The red light stays on for about 3 seconds then blinks twice and continues the cycle again. I checked the fuses and they are fine.

    When i remove the TNPA1906 P9 boards the TV stays on and also the fans turn on, but as soonest i place in the p9 boars the red lights stays on and Two relays click on about a half a second apart and the fans turn on and then they both click and everything powers off.

    my brother told me to remove those p9 boards and get some other ones or replace the ic's

  • Sorry your post went so long without a response.

    If you haven't founda solution, I would certainly contact Panasonic's tech support for assistance (and parts if need be): 800-211-7262
