Hi and welcome to FixYa,
Initially, have you tried the RESET button on the front panel? This may have been proposed by another member of the site who responded ahead but as I am unable to view their solutions, I have to post it.
Offhand, should the above reset be not corrective, options then are:
- consider a DIY (do-it-yourself) repair if and only if very familiar with electronic components & circuitry, use of a DVM/VOM, a soldering iron/station and safe working practices with electrically powered devices. Access to a Service Manual or at the very least, a schematic diagram would be a necessity;
- should you be uncomfortable with a DIY, perhaps your best bet would then be to seek the services of an authorized Sony Service Center or a qualified professional.
If a DIY is being considered, preliminary check would be on the different voltages of the power supply (PS) board and the conditions of the power/filter capacitors. The
schematic diagram of the PS board maybe referenced below.
In some instances, mechanical issues could also trigger the auto-shutdown such as the loading motor, gear, belt.
Good luck and thank you for asking FixYa. Merry Christmas.
