Sony KP-46WT520 TV won't come on.

Does it have the 9 blink error? If so you can get the G board repaired from www.tvrepairworld.com

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.

Two things here.

1) This is a CRT based set so there is no "lamp" involved.
2) The standby light should be blinking a repeated count of blinks with a 2 second pause between counts. Please report the exact count here. This will indicate the circiut in which a problem was detected.

With the above information, we can provide you with a more detailed description of the problem as well as the likely solutions and cost.

Thanks,
Dan

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.

Mine was a bad "g board"

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.
