7 blink can be SC,SD,SU.

Re-install the SC but leave the SD/SU disconnected and the 4 Vfg bolts(gnd bolts that earth these to the SC) connections SC41,42,46 not connected.

ensure sc2 and sc20 are connected.

next to the SC46 connector there is a 2 pin socket, sc50. Those 2 pins need to be jumped together.

Turn the TV on and if it turns on without 7 blinks then it's SD,SU or both.

You would then need to see which one is shorted or just replace both

Looks like Shopjimmy has heaps of these boards and fairly cheap.

any chance you could explain it differently?
i don't understand the jumps one.

Are you saying you followed the bypass test and it's not 7 blinks but something else?

Are you saying it does 1 blink every 3 secs? If so then that's another issue and generally that is a bad A-board.

What about sc3 connected or not connected.

everything is normal except the sd,su isolated , + their bolts, and jumper at SC50.

Yes is 1 is every 3sec red ligth.... is anyone try to fix the board or just replace it..
I did removed bolts, jump the sc board , did the steps you gave me and that's the coming blinking ligth.....

I've got lucky and fixed 1 blink finding corrupted eeprom and another i never fixed. You could have 2 faulty boards. Have you reconnected the sd su plus make sure the earth bolts go back and it 7 blinks again?

Interesting, so the 7 blink was actually a main board issue too?

For the eeproms, there's actually several types and also flash ICs as well.

I don't know which one to try, it was the one that held the panel address data on the 2 I fixed but I've had no luck with 2009 model just 2010.

If it's corrupted data you could use a reader to copy off the good board and the write it to the corrupted one.

You can order these chips programmed from sears or encompass spares

Re: panasonic plasma( TC-P50X1) 7-BLINKS

This is what I got as a list of all the eeproms etc for this model. May not be able to get all as I see some say restricted Panasonic use only.

I can't say for sure replacing any of these will be a fix unless you just want to have a play and see if you can.

Good luck with it.
