I'd turn it off till you can do some basic maintenance.

This old a set could have heat issues. I've lost count of how many things I've used CANNED AIR (see google for those all capital words) to clear the vents.

Continued use can reduce what life is left in this one.

Past the user serviceable area with CANNED AIR, we go inside with all the danger signs about death or worse (your choice) to clean heatsinks and possibly replace heat sink compounds.

It might be due to heating or some issue in circuitry...Hell I am just speculating....My advice is to take an expert opinion rather than experimenting yourself..
