That set probably uses a switching power supply. If it's making a high pitched noise, that probably means there is something shorted on the B+ line, loading down the power supply. My first checks would be the horizontal output transistor and the big diode in the B+ line.
You can probably get some semi-decent $ for that if you fix it. Around here, 36" sets still fetch $200+ in good condition. Don't know how long that trend will last, though.
