The problem is set suddenly turns like video mode without video and audio,
screen also blocks but you can see the channel numbers and function
settings. If I leave it with power on then video and audio comes and stays
on sometimes 15-20 minutes. I suspected something happening around IF
section. If I feed video signal to video inputs then I get the sound but no
video during the set malfunctioning.
