Question about RCA F38310 38" TV
My compliments on the initial repair in the absence of a service manual (or a schematic). The arcing on the yoke does not necessarily indicate on over-voltage or a voltage control problem. It is possible that the CRT has just accumulated dirt, grime and dust further aggravated by the evaporated oil from the leaking capacitor(s). Perhaps you can just try cleaning the CRT especially those in contact or near the yoke. Additionally, you need to inspect the yoke for any burn out insulation (varnish coating). In some instances placing a plastic/insulator sheet between the CRT and yoke would also prevent arcing.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
