There was a firmware update from Sony for power up & down problems for the KDFE42A10 among other models which were made in July 2005. If you go to the Sony website (service/support) you can find a link where you can enter your model # and serial # to see if your TV is affected.

The update takes an authorized service guy to come to you home and load the new firmware from a USB memory stick. It takes approx 5 minutes to do. Mine has worked flawlessly for three years now and it was Sony who contacted me to do the update within the first few months I owned the TV.

You should have this done if your TV is affected. Sony indicated that power on and power off problems could begin after six months or so if the update is not done. Sounds like it may be the same issue unless your lamp is bad.

Also, if you have recently had the lamp door open for any reason, you need to ensure it is closed and locked correctly or the lamp light will flash three times in red and won't allow the TV to start up.

This is all covered in the manual under the Troubleshooting' section and is also referred to in the first few pages of the manual where the LED are explained.

Good luck !

How to fix Sony TV red blinking light on off shutdown

When I turn the tv on the red lights are flashing then it becomes fixed on the lamp sign keeping its red light


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

KDF-50a12U Powers off then standby light blinks 3 times


Please recheck Lamp Cover and make sure it is fixed in its space securely as 3 times red blink shows lamp cover error.
There is small safety switch in TV cabinet under lamp cover that has to be pushed by lamp cover if it is fixed in its position properly. That switch is not being pressed by lamp cover and causing this error.
Thanks.
