One thing to try is an AGC override, as shown on page 6 on sams, this is easy and needs few items and clip leads. Shown below. If it helps get a tuned picture , it means AGC is the problem.
500k potentiometer, linear. 9 v battery. Wire the battery to the outer lugs of the potentiometer. Hook negative line to chassis, and wiper of potentiometer to test point A on chassis. Start sweep from 0v and work up from there to see if it gets a reaction.
