I have this
Samsung LED TV, and up until last night it was working fine. I had it attached to the wall (using a standard tilt mount), and as a result the input plugs have become hard to see. Last night, I was trying to stick my USB pen drive into the TV to watch a movie, and as I couldn't see the input jacks correctly, I have stuck the USB plug from the pen drive into an HDMI input. It didn't go all the way; in fact, the contacts barely touched, but immediately after I did that, the screen went black and all I have now is the audio.
The TV seems to be working, since I can change channels, source (HDMI, set-top box, PS3), hear the audio, etc. But the Samsung logo disappeared from the boot screen, and I cannot see the pictures anymore.
Did I fry my TV's video card, or is there any kind of recovery procedure I can apply without having it serviced?
