  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.

Blinking 7 times after shutdown and after 3 sec repeats the same number of blinks.possible cause is over voltage at horizontal deflection circuit,or over voltage at power supply, or high voltage leak at FBT,or FBT itself is defective.open resistor related to ABL circuit.

Sony kv34hs420 shut off itself
Hi:
If you count the number of error blinks when it shuts this will let you know the error code you are having. If the red led blinks say 6 to 7 times after shutdown then pauses and does it all over again there is a problem with the deflection board or D Boardas sony calls it, It is usually related to the two Power supply regulators IC's on the D-board.

Have Sony KV-34HS420 with no picture or sound. Timer/Stand By light flashes 7 times with pause in between. What is the likely problem and cost to repair?
Hold hair dryer to back right side on high heat for a couple of seconds while you hit the power button several times. It only took 2 times for my set to power on. Good Luck!

Sony Wega
Please count light flashing again. Light flash time is "0.3 Sec" and there would be pause (light Off time) for "3 Sec". Start counting after pause to next pause.
