You have to open it up and inspect the main power supply first, look for blown, burnt, cold solder joints, etc. Do some voltage checking and look for short circuits.

Stopped working and squealing sound


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.
