Sounds like your convergence modules have gone bad. They have 21 close spaced pins to unsolder and resolder. You'll need a soldering iron with a fine point tip and thin gauge solder to do the repairs yourself. Solder bridges between pins are common when soldering these module pins, so have some unsoldering wick handy if you're going to fix it yourself.

The capacitors in the sweep supply and maybe in the main power supply are starting to dry up. Your going to need to get a tech to go over the boards and search out the dryed capacitors. It will take some time and maybe a bit costly. May want to think maybe about a new set? Good Luck

hi, sounds like u need some solder joints re-worked (probably quite a few for a set that old, but your right it`s a great set), price varies by region greatly, I`m in central florida we would charge 75 for service call & 95-125.00 for labor depending on how long it takes to do the solder rework, hope this answers your question, get it fixed it`s waaay better than the new hd (ha ha ha) sets, video-tek
