Hi. I have a Sony WEGA FD Trinitron color TV. KV-TG 21 / KV-PG 14 MULTI SYSTEM PAL/SECAM/NTSC4.43.3.58 In this days it have searching problem for TV Programs. Because the VHF HIGH can fine five TV programs but VHF LOW and UHF can’t fine any TV programs. In my mind me be VHF LOW and UHF turn OFF but I can not salve this problem. Please show me the way how can I salve this problem? Sincerely yours, Hakim Sharifi
