Default Re: JVC EM55FT everything ok but cannot find any channels

well now you have "narrowed down" the problem.... :-) It is likely a problem with the main board which houses the inputs and conversions. The menus are generated internally and don't go thru much / any signal conversion / capture and the display basically works. You need to start checking voltages in and around the hdmi area especially 5v which is used in the protocol. When you try to select an hdmi input, what does the screen display? You can / should trace voltages coming from the PS to the main and into the main.

although hard to tell from the pictures, there appears to be some bulging of tops on some of the caps on the main board.... maybe.
