There are about 33 volts that come out of the flyback that feed the tuner, followed by a filter and zener that keeps the voltage at that value, see if the zener is shorted when it is heated, do the same with the filter.

using the rca connection inputs, the ones that usually connect tuners, dvr, dvd players, among others, have to get an rca tuner or hire a TV service that gives you a good tuner for rca is what I can come up with regards
