Hi,
Red light blinking 3 times shows problem with lamp cover.
Lamp cover is not fixed securely in your tv after lamp replacement. Lamp cover is first thing that was removed to replace lamp, check lamp cover and make sure its back in place properly.
Thanks.

Problem with the Sony FD Trinitron WEGA KV-27HS420 27" TV WHEN TV IS TURNED ON IT SHUTS itself off in a second or two and a light on front blinks 6 times.


Most of the time this is caused by two ic chips on the circuit board, ic8001 and ic8002. These are components that can be replaced fairly reasonably. If you call a repairman it should cost 95-165 us dollars. However, this is just an educated guess. Good luck, Russmann.

KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.

There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.

If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.

I had the same problem with a old Sony TV.

To find out if the problem is temporary
  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 light is still flashing the tv has stop working and you will need to buy a new one.
