I need some tech help here. Last night fell asleep with TV on (Sony KDL-52v5100). When I changed channels this morning I lost my video and got sporadic sound through the AVR. I Chased the problem back to the TV. It seems all my HDMI (4) are dead. Display works,( I get the "Bravia" and "no signal" msg). I cannot check component input as I do not have any cables. The system works fine when another TV is connected. I believe the problem may be the Digital Video Board it contains all the inputs for the TV. Does any body know if this board is "plug n play" or does it need to be soldered in? Has anybody had this problem? Does it sound like I am on the right track? I found the board for about $50.00 the TV is 3 weeks out of warranty (parts only.. anyway) If I can remedy this on my own it would be much cheaper. Also I have had this TV recently ISF calibrated are those settings on this board? Thanks for any and all info. Chris oops....Guess I should have posted this under TVs, Displays.
