Make? Model? Chassis #?

RCA 14F512T

It's a little $100 set so the parts warranty is irrelevant. If a $3
pot will save it from the dumpster that would still be a good thing.
Thanks.

As Andy Cuffe wrote in a previous message, you could try going into the
service menu of the set to try to see if the green color can be adjusted
there. At this website they describe how to get into the service menu of an
RCA TV (may or may not work for your model):

Just be aware that you might screw up the TV more than it already is by
changing any of the settings there, so before changing anything write down
what the value is, so you can change it back if it doesn't work.

That is very interesting. Thanks. So far I haven't gotten into service
mode but maybe if I try enough key combinations... I might find it...

According to another thread, someone else's kids managed to accomplish
it...

You also have to be concerned if it is the low or high green that is
the problem, or both. If you can somehow get a gray scale pattern into
the set, you'll be able to see this.
