Most likely reason is a blocked air filter, preventing sufficient cooling air from reaching the interior of the case. Remove and carefully clean, by washing in warm soapy water, or replace the air filter sponges. NOTE! If the sponges are old, they may fall to pieces when you try cleaning them, so you may have to source replacements from a Sony Service Centre.Alternatively, one or more of the cooling fans may have a faulty bearing causing it to rotate slowly, requiring that it be replaced.There may also be a problem with capacitors in the projectoirs power supplies

Make sure there's nothing impinging on the fan, and the filter is clean.

Check the fan is working could be shutting down cause overheat

If the Panel Key Lock feature was set to 'on' so that the Remote Commander could be used the user manual, page 34, says, "If you press and hold the MENU key for about 10 seconds when the power is on, the lock will be released and "Panel Key Lock" is automatically set to "OFF"."However, if the Security Lock feature was set, which requires a password, and you don't know what the password is you have to call the Sony Customer Service center and be ready with the device's serial number and your personal information.
