I have an RCA 19" TV that's about 10 years old, thats hooked up to cable service. The cable comes in and goes through a Zenith VCR, then out from there to the TV. Recently, it's developed an intermittent but frequent and annoying problem that some channels are scrambled or just snow. It's always between Channels 30 and 50, but sometimes it can be a lot less - like chs. 45 - 50. Two days ago it was just Ch. 50. Most of the time, reception is okay on all channels. All other channels (2-29 and 51-78) seem totally unaffected at all times. If I turn on the VCR and set the channel through it, I can watch TV unaffected if the problem is occurring at that time. Usually it resolves itself if I leave the TV on for a while. I was curious what could possibly be going on with the TV. Thanks in advance.

It could be a problem that older RCA TVs were notorious for called open tuner shield ground . The next time it does this, gently tap on the TV's case and see if this has any effect. If it does, it's time to replace the TV, or get someone who knows RCA's to re solder the tuner shield.
