Any suggestions on how to fix black tv screen. I get audio but no menu screen. Have tried hdmi and component. Before I stored this nfusion hd receiver I used the component screen. My Samsung HD tv shows mode not supported! The nfusion receiver face turns on to the last programs titles I used to watch but no video, only audio. Unit was stored for the last two years. Have tried the menu-channel down-volume > channel down-ok-volume> several times to no avail. Seller, maker no help. Noticed this unit is now being sold for about 1/2 of what I paid. I hope this last statement is not my answer. Same cables work with my Fortec Star Mercury receiver. Thanks for any responses.
