SOURCE: got a new T-con but no luck
is your back light constantly on when you are not changing channels.if so replace the main board. can you see a menu if you hit the menu button ? that is generated by your main board..... replacing the t-con will only correct vertical lines in the pic.

Rolling or sync bars can be caused by bad caps in the tuner. I also had a brown film all over my board. Clean with alcohol and repace the 2.2/50 caps in the tuner. l

2 blinks error code is definitely a 15VDC SOS detect, but this error code does not means that the fault was came from the D board alone. Remember that this is a supply voltage issue also. In the service manual, stated there that the test point is in the D-board (not specifically replaced the D-board).
Let me know the reading in the connector (P25) pin #1&2 in the D-board to assist you further.
Also just for the confirmation of 5vdc, let me know also the reading in (P25) pin #5&6 in the D-board.
Note : to have an accurate reading, place the test prod of your multimeter on the test point prior from powering on the unit because the supply voltage will cut-off after the self test.
