Hi everyone,
First of all, english is not my first language. Really glad to be here, read a lot, and i have a long story, hope you're patient and ready to help, i really want to fing what the hell is happenning. Since a month now, i'm having weird problem with a Panasonic TC-P54VT25.
One day i tried to turn on the TV and the red light started flashing. So i've unplug the power cable a plug it again and same thing. Since then, when i plug the cable i hear the relay click, 5 seconds later, i hear the relay click again. Then, when i try to turn to TV on, the red light will turn on and 3-4 seconds later i hear the relay click and the light flash each 3 seconds.
So just to be clear, the light flash....3 seconds pause...the light flash...3 seconds pause.....And continue that way....
In the beginning, because i didn't want to believe my TV was good for garbage, i've begin to unplug and plug back the power cable and immediatly powered the TV on. Each time i was able to get the TV working. Sometimes i had to plug, unplug the power cable 6 times, other time 15, 32 or 19. But each time the Tv finaly turned on.
I took the TV to a repair shop after i called Panasonic, they refered me to this shop. The guy told me the panel was short and a chip on a ribbon cable was dead.
So i took back the TV and did the same thing. Plug out, plug in, power on. The TV ALWAYS turned on, just like before, after 2 try, 6 try, 25, or 32......
So i took a chance and buy a TC-P50VT20 ( with 8000 hours, you may tell me what you think about that, because i though the TV was brand new like, little bit scared with that 8000 hours in three years, anyway ), because i read that the A-board and the power supply board were the same model number.
Just to let you know, i've chat with Tom66 on a different forum and we finally try to swap the A-board. So i' unstall the A-board from the TC-P50VT25 and installed it in the TC-P54VT25. Didn't turn on the first time, neither the second, but on the third it turned on. So i turned it off, and after that same story, would turned on after 6 try, sometimes 23, or 15, but ALWAYS turned on.
Next step, i swap the power board from the 50VT20 in the 54VT25, same story again. Put back i place each TVs, and it's been all night right now and the 54VT25 is turning on, but i've to be plug and unplug and plug and.....
I've some knowlodge in electronic, but i was reading things about ICXXX, and jumped PIN XX to PIN XX, bought the TC-P54VT25 Service Manual Chassis, but i'm a little bit scared to blow out the TV, so i'm careful. The TV doesn't work like it suppose, but with patience it work. Last time it turned on, i've let the TV on for 60 hours with no problems at all.
I'm really wondering what the hell is wrong, if the panel was short or the chip on the ribbon cable like the guy at shop said, the TV wouldn't even work, right ? Why would it sometimes turn on and work flawlessly, but sometimes the famous 1 blink code.
I've inspect bad caps, check the fuse, burnt on bords, i'm really lost here. Because i know the TV would finaly turn on after plug and plug and plug, and don't want to put it i the garbage right now. I called Panasonic a few times and they said they will offer me a rebate on their new LCD 2014.
( I would also appreciate if you share what you think about a 8000 hours VT20 plasma, really though it was new ), But right now, anybody who wanna jump in, be my guess..... Hope it wasn't to long for a first post, maybe because it's been a month of research, been up all night long, and on this TV for a week now ( I'm out of work right now so).
So thanks guys, i reaaly though i had it when i bought the 50VT20 and swap the A-board, but same problem again, what you think.
