I have a 25" Hantarex Polo that stopped allowing me to adjust the horizontal size and the picture is squashed. The picture shows the problem. I have replaced the pot on the remote board, but that did nothing. It will begin to adjust at the first maybe 1/16th of a turn, then it stops. I have also tried adjusting the horizontal width coil on the main board and that did not work either. Is this a cap problem or something more serious? Thanks for any info you can provide.
