I would like to know what the 7 blinks mean exactly, have read several excuses.
Heres my paltry dilemma....
42PZ80U, when i received it, was doing this, Powers on, the screen initally looks good to come on but would fade within seconds, but still some light. No functions, audio, or pic, P-supply stays on, fans run.
Was told possible logic or (D) board (mounted under "A" board), and if i was to disconnect the D5 cable that connects the 2 boards, should get a nice bright white raster.
Well I do, nice and bright full screen white light....lol
OK< convinced it was the D board, I found one on ebay used, but guaranteed, for a grand total of 40$(Product+S+H)....I get the board in today(Mon), I replaced the old one.
Now, I get nothing but a repeating 7 blinks of the front LED, Power supply kiks on normally, then after a few seconds, off again.
If i put back in the Original D board, P_supply STAYS ON, and once again, disconnecting D5 will produce a full white raster.
Now can anybody here tell me that the board i ordered is bad???....have 14 days to return, and I just want the friggin TV on, no money back wanted, I see he has more of these for sale.
OR, can somebody tell me if I'm even barking up the right tree???
Thank you oh great intelligent ones!!.....seriously!!
