Question about Televison & Video
I have a Sony Trinitron KV-20TS27 from 1991. After I turn it on and plug the TV Cable everything seems fine. After 1 minute it loses the signal and shows snow.
Still there seems to be some weak signal on channels 69 or 88. I think this are some kind of local channels. When the TV Cable works, channel 69 shows something else while 88 has nothing.
I think the TV is switching from TV Cable to local stations after 1 minute, but it does not switch back.
Either that of your tuner block is acting up. Most Sonys of this production year uses a tuner block that requires 33VDC tuning supply. It has been known for this zener to fail or the capacitor parallel to it. At times, it could just be the tuner block itself.
Should you venture a DIY, it would be to your advantage to have access to a service manual or at the very least a schematic diagram with voltage readings.. It further requires familiarity with electronic components and circuitry, use of a DVM and a soldering iron. Should you be uncomfortable going this route, then perhaps your best bet would be to seek the services of a qualified professional
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
