Some component(s) in it have become thermo sensitive. It may be some of

suggest
to get a new one, rather than spending time and money on fixing it.

I've fixed a few similar units, the problem in every case was a couple bad
capacitors on the output of the power supply, this is a nice simple beginner
repair.
