The problem is in the vertical deflection circuits which is responsible for giving a full picture. Since the set is 8 years old the money would be better spent on a new tv since more frequent break downs in other parts of the set would be more likely due to age.
Remove back fron tv locate line flyback transformer
on this transformer there should be two adjustment controls very carfully adjust the bottom one, do not adjust to far as picture will have fine white lines on it
Sylvania MTS/SAP TV. I don't have a remote I accidentally hit the ''menu'' button on the front. Now I can't get the TV to show anything but static -- like there is no signal coming in from receiver (either through input jacks on front or on rear. Menu gives various options, but none of them gets me back to being able to see the picture.

Your set is shorted circuit condition. The power supply is making the noise. Unfortunately almost any of the hi current circuits will do this. If picture went out 1st look for video or hi voltage problems.
If you unplug the unit for an hour or overnight, it should go out of sleep mode. If this dosent work then its not in sleep mode and the set has a problem in the power supply or the sweep circuit. Sorry you should seek a pro to assist you in this repair. Good Luck
