Panasonic TX-P50G10B 3 Blink Error

[bubsy123]

Hi,

I've tried searching on how to resolve this error however haven't found much help as it seems to be one of the rarer ones.

I've got a Panasonic TX-P50G10B Plasma which blinks red 3 times when turning on. I tried changing the power board however that didn't help, and upon further research it looks like its the '3.3V SOS D Board' error. I can't see that this TV has a D board though.

Can anyone help me? Thanks

There's a manual here but takes some sorting through.

Thanks for your answer, I've had a look but I'm not too good with looking at stuff at a component level. The boards are pretty cheap so I was just looking to change one of them.

I found the manual for the TV and it said the A (AV) board is the suspect. I changed it today however the problem persists, with one time a 5 blink (5.5V A board SOS). When I changed the A board I forgot to plug in the A33/A31/A32 ribbon cables to the C1/C2/C3 boards before turning it on, could this have caused the new A board to fail and give out a new 3 blink error? Or is there likely to be something else at fault?

Thanks for any help.
