FY HD800-C III

[Acs76]

Anyone can advise? Setup my box using hdmi cable but got sound no image. Screen is blue. But when I switch to the red/yellow/white cable, able to work. Anyone can advise to resolve the blue screen with hdmi cable? Many thanks in advance

My suspicion is the HDMI connector to Mobo is loose or not connected. This is 1 of many FY's box common or regular happening. there r 19pins all very close to each other, need a very VERY VERY steady hand and a pointed solder bit to resolder every pins of the 19 oins. Good luck to u.
