More than likely the fan above the processor is not working. Or the vents are clogged on the computer case due to dust/dirt. Ventilation.Check the fans.

Sony KV-34HS420 shuts of and stand-by light blinks


  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.

No sound or picture now


The set may have shorted the horizontal out put transistor since it kept coming on sometimes. This could be cause by the driver transformer arcing causing a "spike" in voltage going to you horizoltal out put transistor. Stargazer
