Question about RCA Televison & Video
It's a defective audio amplifier chip - either it heats up too much and its performances degrade or one of the capacitors from the reaction loop has aged and when it heats it's losing its isolating properties.
You need to open the case and test the amplifying IC. If you don't have any testing equipment then just unsolder all the capacitors and the IC, make a drawing of how they were, buy identical replacements and solder them back.
