Very patchy. Some weeks I'm flat chat, other weeks I'm doing the Times cryptic crosswords - my way of keeping old-timers at bay.

Hi Shaun,

Code 14 is generated if the is an abnormality during the data exchange with the standby CPU ROM, so yes, I'd say the A board (main)

Hi,

I also have this model of TV tx-p50u30b and in the process of trying to repair this tv to progress my learning in electronics and repair. I have the following problem and what I have tried to identify the cause but cannot seem to pinpoint the problem board:

1) Turn TV on - green light flashes for a few seconds followed by 7 red flashes.
2) Turn off tv, disconnect SC20, turn tv on - i get 8 red flashes?

I have checked SU, SD and SS boards (FET's, Diodes and buffers) all seem to test okay.

I also tried reconnecting SC20, disconnecting SS11, turn tv on - I get 6 red blinks. I am confused as to what this means. Could someone help me with the diagnosis? Your help would be much appreciated.

Best

Ben
