You have some leaky filter caps - C2C52 = 10MFD 50 VOLT (off base of Q2C51 on signal board) also check C2P05 = 100 MFD 16 VOLT off pin #3 of IC2P01 and C2P08,C2P03 = 100 MFD 16 VOLT

These sets have capacitors that will go bad, but without a good ERS meater that tests these in curcuit you could be spending a lot of time doing nothing, But the most common is to find the 9 volt reg on the signal board and change all within a 2 inches of that regulator

the DM and/or the FMT board are going bad. the chassis needs to be rebuilt. check out www.tv-techs.com
