Not sure which chassis you have. Look for a ctc chassis number. Most units have a programming function that can be addressed from a soft button on the front of the unit. Also just try going in the down direction with the channel select button to see if it goes from channel 2 to a/v input. A chassis number would help me. I was a Thomson authorized repairman for years but it has been a few years. good luck
Proscan is owned by RCA, but they have very little support for that product any more. RCA created another company to deal with the product it is http://www.oncorpus.com/ They may have support for your TV set.
The chassis number is CTC169CG5 (This may help you find service data) since this same chassis is used in RCA models.
Any shop servicing RCAs should be able to find this chassis number and provide service to you, if RCA or Thomson Electronics is non-responsive to you.
One thing that comes to mind is the two main connectors on the power/deflection board. They have ribbon cable in them. If they are white in color. One of them plus the one on the convergence board that is the same size, needs to be replaced. If they are black they are good. Part number is 258686. If your serial number is between G13XXXXXX and G26XXXXXX this is a very good posibility.
Click on "publications ordering" (in the list on the lefthand side of the homepage) Click the box for service information. Enter the model number (or click the chassis button and enter the chassis number).
In the list of documents you can purchase for $40 ESIATC32X -- the service manual on CD for your set.
This disk will have the info you need.
If you do decide to purchase it (and I highly reccommend you do so), send me the alignment chapter and I would be happy to post it for others who have the same set on my homepage.

There is much more likely wrong with the TV. Resistor don't normally burn out with help, say, without a failing flyback transformer and possibly taking a transistor or two with it.
If you need the manual, go to
and type in "F31317" into the search field, you will several listings.
If you decide to replace it yourself, here's some more part numbers in case you need them.
Necessary parts: Transistor(Q14401)
Main Voltage regulator Q14101
Resistor R14109 open.
Research indicated the flyback transformer most probably bad
Hope this helps you.

I think you have a problem in the vertical circuit in your tv. It sounds like you have a loose solder joint.
The set would have to be taken apart and re-soldered. You really have an RCA chassis inside your tv. RCA's have a lot of bad solder connections.
