Sony TV LED & Blinking Codes - What Does It Mean When Standby/Timer Light Flashes Sony has provided a "self-diagnosis function" with your TV, that in the case of abnormalities or problems the LED or red blinking light on the Timer/Standby indicator flashes a number of times to indicate the issue.
when there is trouble with your Sony Television set -- it indicates the issue in either the diagnostic mode, or even more commonly by flashing a series of LED blinks or flashes on the front of your television. Each set or frequency of the blinks indicates a very specific problem with the television itself.
Sorry but unless you may be able to repair the television set yourself , please call a local repair shop to the have a repairman sent out,,

Sony KDF-50WE655 will not power up. Red blight blinks 4 times


4 blinks shows problem either one or all 4 fans are not working AND internal temperature high error.

If you are familiar with TV repair and know basic electronics then unplug TV from AC outlet an take off back cover and check fans are running?

Kdf-60xs955 red continous blinking lamp light


It's in standby mode.

Do a reset and see what happens

While holding down the reset button on the remote
Press the power button on the tv
(The tv will turn itself off the back on)
Now release the reset button

It sounds like the lamp needs replaced.


Please rate this a fixya
