Pioneer PRO-506PU Plasma

[ljintexas]

Blue LED blinks 8 times, then 12 times. I am going to look for a service manual.
Any input will be appreciated.

Thanks

Tom66 is the man for pioneer plasmas wait for him to post dare say he will. Normally 8 blink is due to a failed 1.8v voltage regulator on the av I/O board.

I don't think that applies to these models unfortunately. Older models. I'll look out for a service manual, it will have error codes in it.

Re: Pioneer PRO-506PU Plasma

d2fx, yes..I do.
Tom, I think I found a manual..both errors point to IC5206 communication on the digital video board..shows to be BR24L04FJ..I do not have a hot air station and it is smd..8 leg IC
Might be an excuse to buy one..LOL! I just found the board for $28
