I have an RCA TV Model F26634SF. It occasionally and on its own
changes all channels to the programming on channel 20. Resetting TV
does not work. Other TV's in the house are not affected so it is not
the cable company. It will keep this programming for awhile then
change back to normal. I am assuming it is a tuner problem, but would
like to know if anyone has seen this before. Thanks

Does it do this in a dark room, with the shades drawn and all lights turned
off?

I ask, before fluorescent lights put out a modest amount of IR, which can be
picked up by the remote sensor. I saw this happen with my Sony Hi-8 VCR.

Find the little red window where the infrared remote sensor peeks through,
and cover it with black tape for a full day. This time of year when the
sun is changing angles, it can play tricks at certain times of day when
your TV is in the right place. For a couple of days each spring and fall,
my set was positively haunted until I covered the remote sensor.
