I am desperate
Guys I tried all the thing you told me to do, more than 20 cables types, I tried to pull the cable out/in a little, but what ever I do the nothing change on the muted black screen, I tried to connect my DVD, laptop, camera, ipod, xdaII, with all the possible way to this AV stupid port but didn’t work , there only 2 things I didn’t try, getting the Agency AV cable and opening the AV compartment in the middle to see if there any cables disconnectedrom inside,
Any advice what I have to do now? one has the instructions manual for assembling reassembling this? I don’t want to break anything
