 tv stuck on A/V input..

Hi,

I have a TV set which has both RF and A/V inputs and circuitry to
automatically switch between the two based on whether something
is connected to the A/V inputs or not. For some reason the TV has
now got into a state were it thinks there is something connnected to
the A/V inputs even though there isn't. Has anyone see this before?
know what I should be looking for? The TV is a broksonic - CTSG
9369TC.

thanks!

The name tells it all, Broken sonic.
Odds are since it is a "junk" brand that the manufacture that actually
made the tv is long gone and you will not be able to get a hold of any
kind of service schematic as is all to common on these type of fly by
night "name" brands.

Try the easy stuff first - insert and remove the A/V plugs a few times, some
of these use a contact in the RCA jacks to make/break a circuit based on
whether something is plugged into them and contacts can get dirty.  Probably
not but worth a try.

I have two possible solutions that might help you that are external to the TV
quick fixes.

1) Some TV's will have the tuner turned off if any A/V input is actually
plugged into the A/V input on the TV, because some TV's are designed for the
tuner to shut off when an A/V input is plugged in and the circuit looks for an
A/V input instead of the tuner. I have an old VCR that works the same way i
described. The easy fix is to disconnect the A/V plugs from the TV.

2) If the TV is designed to have a switchable A/V input to allow you the user
to switch between the TV's tuner and the A/V inputs with the remote, then you
might have to use the menu and autoprogram features on the remote to reprogram
the tuner. This is especially true if the Tv had been disconnected from the
power source for more than one minute, or if the outlet it is plugged into had
an outage for a long period of time.

It is a fact that on any TV that if you lose the power, the memory on the Tv is
cleared and you have to reset all of the channels you had originally tuned into
it after an outage.
