Evening all.
Have an LG 50PK750 that turns on, has sound but no video. Previous owner tried to do a repair on the power supply board, but did a horrible job (burned through traces, unsoldered some smds as well) so I got a replacement. New board in and the same issue.
VA - 60
VS - 204
jumpered 51 & 52 on the main board and removed the p31 cable. No test patterns.
From searching it seems that most that have similar issue they do get test patterns which means the main board is bad, but I haven't found anything that helps me figure out what to do/test next if there are no test patterns.
Any help is appreciated.
