Sony KP-46WT520- STANDBY

Need to know what the problem is such as the led blinking X amount of times. Your model is famous for the zero cross error which is 9 blinks.

hello, Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negitive).

There is some problme in G Board (power supply board) in your Sony KP-46WT520 tv that is why standby light blinks 9 times.
If you are handy with electronics stuff repair and can test/ replace parts in circuit board then let me know to provide you more technical info to fix tv problem.

That is a diode in the sub power supply, it is a small board with only a few parts on it to the left of the d board, for the zero crossing detector. D6301 sony part number 6-500-567-21

High voltage in TV got problem and thats why TV gives 10 time blink error code.
Qualified TV tech will fix it as its bit complicated fix.

Called sony and they said send it so we can help fix it.
Mine was a bad "g board"
Sent it to PA (penssylvania)
And they fixed it for & $88 you have to ship G-Board to them and they will return after they fix it if not repairable they will tell you.
(No charge until they fix it.. )
Mine works now and ready for superbowl....YEAH ! ! ! !

Replace Diode 6301 and D6116,6117

make sure it is 9 blinking it may be 10

it's blinking 9 times?

according to all of the local repair shops, 9 blinks on the stand by light means that the power supply is shot. eand and every one told me that the set had to be taken to a service center for repair, since the power supply is in a board, not seperate. cost around my area is between 50 and 150 for the parts, labor from 100 to 200.

My view is never buy a sony again! 90% of the service shops will not touch sony, saying thay cannot be authorized by sony unless they pay sony for the certificate.
