This TV is really bugging me now on the bench here is my issue. The TV seems to start up fine , back light is good (LED) sound is fine , but the screen is dark with very faint black bars going down from top to bottom, and the darkness does vary slightly with scenes here what I have found so far.
12 v , 24 v , 3.2 v Present on output from PSU.
No obvious cap issues
I have replaced the TCON board as per service manual
I am now at a complete loss, dont know what else to try. I hoping its not main PCB as this makes the TV a right off in my opinion. |
