When i first got tv powered up but no picture. I opened it up after browsing internet for solution and disconnected y-sustainer board and now I have poor picture and sound. I guess I need to know what to fix so that I can plug y board back in to fix picture. Thanks
The y-sustainer board is out and the tv won't work if it is plugged in. It only works when the "y" is unplugged. The picture is not as good because of it.
