initially the tv was totally inoperative, lifeless, led standby off . When examining the source (PSU) I found FH101 250v / 5A open, burned U501 (NCP1207A), Q501 (FPQF6N80 shorted and resistor R514 (10R smd) open.
All the above mentioned components were replaced, soon after the exchange the TV reconnected with image but without video using both antenna (AR) and PC (via computer)

program the tuning of the channels, detect some channels but even then the image of the tuned channel does not appear.

необходимо, чтобы телевизор снова работал нормально:
-> изменение указанных компонентов и обновление программного обеспечения (прошивки)
