Panasonic TX-P50GT50E

[Dejan84]

Hi guys i have Panasonic TX-P50GT50E and need eeprom for IC9304 and IC 8902. I just can't find them anywhere...
A-board is TNPH0988 1 A.
The TV has 13 red blinks problem. When I plug power cord it starts and stays on smartviera logo for 2-3min then reset itself and
do the same thing one more time. After that it goes to 13 red blinks.
Panasonic service manual says it's Emergency SOS from A-Board.
All check ponits for voltages are fine only STBY5V on power supply is 4.48v.
This A-bord is very difficult to find so I have to get it fixed...
My only guess is to reflash eeprom's but i cant find them.

Thanks

You can try flashing the firmware using an sd card

Problem is that it just show smartviera logo and stays that way. Trayed on SD and USB1 same thing.

I had the same problem on my TV ( Panasonic Tx-P65vt50e). Not exactly the same model, but same board (tnph0988).
The processor's thermal pads were dry and it cooked itself to death. I reflowed it with a hot air iron at 180°C, but you can do the same with an oven, 180°C for 10mn.

Maybe it's too late for you, but it may be useful to another person
