A 3 flash pattern indicates that either the lamp is not seated correctly or that the lamp door is not latched properly. It can also be a fault with the switches that sense whether the lamp is seated or the door is latched. Try reseating the lamp and relatching the lamp door

SOURCE: Try to turn on the TV, the indicator in Green turn

Hi guency,

This is an indication of out-of-regulation in the power supply section. The very common caused of this fault is the dried-up/leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit and blinking error appear. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Also, bad solder joints can produce the same symptom, it is hard to spot, you should use table lamp/portable lamp for finding the cold solder. Secondary reason of fault is the open fuse/fusible resistor in series with the output of regulator IC/transistor, shorted/openRegulator IC/transistor, shorted zener diode(all are in the power supply section) and the microcontroller. Best that you check the output voltage of each regulator to determine where the fault came from and narrow the job.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Also check if your unit is under warranty /extended warranty, avail it because the manufacturer of your unit will fix it for free. Don't open the back panel, this will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

Sony Grand WEGA KDF-60XBR950 60 green orange green red flashing light


3 blinks is a lamp cover error, did you make sure that the lamp cover is screwed in tight? Also check the lamp cover for deformity, there is a problem with your model where the set over heats and melts the lamp cover a little causing it not to make connection with the lamp cover switch. Let me know if you find either of these problems? If not we can troubleshoot a little further.

No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

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.
