This is a very common problem, caused by failure of IC MM201 (usually located on the plug-in board containing the IF can, which you should also repair as long as you're taking the board out; solder connections commonly fail on this board causing intermittent or total loss of tuner video). The high-pitch whistle's the most common symptom, but it can cause a number of things. Any time there's a sound problem such as low or distorted sound, whistles, static, etc, change the IC. It's available from MCM Electronics for about $15 There is a kit of surface-mount caps available which supposedly will repair these little buggers. It's not worth the time and effort, just put in a new one. BTW, replacing the part is not difficult, but does require soldering skills. If you're not comfortable with soldering, you could remove the entire circuit panel (I believe the M board) and take it to a shop. If you call around, you should be able to find a servicer to replace the part for a nominal fee.
