Hi all i'm stumped on a plasma. So i have no picture no sound, but i checked out power supply and all voltages seems fine. Now I do know the Ysus was screwed and bought one off ebay thinking it would solve problem, but no luck. Checked buffer boards no shorts and diode check of buffers looked good.
Plugged in tv, disconnected ysus first, nothing on screen no menu no nothing, next plugged Ysus back and unplugged X board, nothing on screen no menu no nothing. Next unplugged both, nothing on screen no menu no nothing.
Also, when I plug the tv in I don't hear hear the sumsung welcome/turn on sound, now I have no idea if this tv would give you that sound or not, or if someone could turn off the welcome/turn on sound.
Logic board led blinks normal.
The other thing is if the tv was previously set to HDMI with a direct tv box, if I dont have the box connected would I even have sound at all? I tried the source button on the side of the tv & remote, hoping to switch to antenna, but I can't see anything on the screen so tough to tell if I'm pressing enought to select antenna. The other thing is I looked in the owners manual, and I can't tell if I hit the source button and land on antenna do I have to hit an up down button to actually select it.
Needless to say I'm stumped and any help would be appreciated.
