TV Repair Questions? Ask a TV Technician
yes it was working ; tried other cable and tried xbox that peviously worked; the input is right
no xbox not working either
is their some kind of fuse on the imputs?
Okay I understand, so it's all of the HDMI Inputs on the TV that will not work then. No there isn't a fuse for the HDMI circuitry on the Mainboard. HDMI is very finicky as it is the only connection that carries 5 volts of Bus power down the cable to transmit the signal. It is prone to failure from slight surges (even with a surge protector), Arcs from within the jack, or a cable that has failed. Unfortunately there are no settings, or buttons you can change to allow the HDMI jacks working again. You will need to have the Mainboard on the TV replaced (It houses the HDMI jacks and the AV connections). Average cost for this type of repair is around $275 parts and labor.

If you're instead looking to repair the set yourself, and save money, then you can purchase the Mainboard for your set and replace it yourself. It is a plug and play board and available at the link below for purchase:
