I have a 22-year old Panasonic TR-205 B/W TV (transistors, no tubes). I am trying to get it working again, and fixed a problem in the vertical deflection circuitry (bad capacitor trashing the vertical sawtooth voltage). Now I have more subtle problems: mainly, a very grainy picture. Very white-noisy. Otherwise, stable (no roll, etc.). I guess I'm looking for a knowledgable TV person who I can correspond with, who can suggest things to look at. I'd appreciate any help! -- -Jeffrey W Percival (jwp@larry.sal.wisc.edu)
