initially was not even calling. I went to check the source by finding the MQPF6N80 mosfet totally short and the smd 10R resistor (R514) open beyond the fuse of the input and also the U501 (NCP1207A) burnt. After replacing these components the TV turned on again only putting an antenna and tuning the channels detects, type, 7 channels but the picture does not appear the same thing when I put the PC option, it is without image. only have no video signal. This TV has already come from another workshop.

after completing the tuning of the channels by the ANT (AR) option, the image appeared all dotted and multi-colored. I suspect the defect is on the t-con plate
digital channels found -> 15
analog channels found -> 0
I exit the menu and when I select a broadcast channel, for example, the tuned channel nothing of the broadcast picture appears
