Question about RCA F32450 32" TV
Hi, It appears that your unit has switched to protective mode (hence also no HV). When you unplug the set and "speakers thump", that would mean that the low B+ is still active and your SMPS is good. Your post "No high voltage" leads me to believe that you have a fair idea of working inside a TV. Should you venture to do-it-yourself (of course the standard precaution when working with TV units specially HV section), try checking: 1. an inductor/coil supplying the main B+ to the horz (probably L14???), resolder fully; 2. the Horizontal circuitry with special attention to the HOT (TL0?) and the FBT. It may also be a good idea to have the FBT ring tested. Other than above, it's the usual check with your VOM with attention to B+ line. Hope this be of some help/idea. Good luck and kind regards.
