So I have this set that I was told when I got it that it had a horizontal line on the screen. I powered it up and found it would not turn on but blinked 7 times. I trouble shot the SC board and found it to shorted on SC2. I sent the SC,SV,SD and SS boards to PTS electronics to have them checked and repaired. They found the SC board to have multiple failures (transistors and diodes mostly)They repaired the SC board and tested all the boards together and once all were working they sent them back to me. I installed all the boards and tightened the screws securely. Made sure all tab ribbon cables were inserted properly and securely then connected all other connectors. Powered on the set. The sound worked but now there were multiple horizontal lines. Some thin some thick. Set stayed on for a few seconds and then turned off. Tried to restart, heard the relays clicking and then got the 7 blinks again. Very frustrating to say the least. Can anyone help? Is there something I am missing? Maybe the main board? I just don't know.
Thank you in advance.
