Panasonic P50S30 14blinks

[don_mayor]

fellas, i need your help. i have a panasonic P50S30, it went dead last year and started blinking 7x. Panasonic had a technician come change the SC, SU and SD boards, it worked. 6 months later, it went dead again, blinking 7x and this time. i'm out of warranty.

i bought an SC board online and replaced the the burnt out one. TV went from 7blinks to solid red and still no picture. when i hold the power botton for more than 5 seconds. it starts to blink 14x.

i've changed the P-Board, A Boards and still no picture, still solid red and 14x blinks.

I need help or i'm gonna have to part the TV out.

thanks

It's usually advised to swap the SU and SD at same time as SC replacement.

yeah i knew, but i examined the SD & SU boards and they're both brand new with no burnt marks.

The buffers on these can fail without obvious burn marks.
