Your problem is in the signal board. The signal board is also called the "main board" sometimes. It has all the RF,component, audio and HDMI connections. You will find capacitor, location C2003. It is a 16 volt 470 Mf capacitor. Bend this cap back and forth from the top carefully. Do not pull off. bend back and forth, till it comes off. You may solder a new one from the top.Be sure you install the capacitor polarity correctly (positive on positive, Negative on negative). It will be almost impossible to unsolder, and remove legs from bottom of board. With some effort and patience you can remove the board from TV and repair. Thanks for asking me. Sincerely, Matt of Martins TV Repair.
