Can you unplug the TV for about 15 seconds, and then plug back in and watch the stand-by light. Tell me how many time the stand-by light blinks in regular intervals. If it doesn't blink at all, you need to change a fuse on the g-board. Once this is done run back through the stand-by blink light process, and more troubleshooting can be done if problem isn't already solved. If the stand-by light just keeps blinking with a count over ten just tell me, and I'll look for other possibilities.

    I have seen blinking problems like this before, and strange enough just replacing the power strip worked. You may want to try another power connection, or power strip too.

    Thanks for specifying which light is blinking. This could be power or lighting problem.

When I turn on my sony kp-46wt520 tv the sound comes on for several then the red light blinks 5 times, and the tv shuts off. this problem happened gradually, it used to come on after several attempts but...


Hi,

I am sorry to hear regarding the trouble. A 5 blink error code indicates a white balance error. This can have many causes such as incorrectly adjusted screen voltages on the CRT's, a bad CRT drive IC, or a bad picture tube/CRT.More often, it is due to bad driver Ic's The Ic's are labeled MCZ3001D(B) and they should be found in the middle of the deflection board.If you call a technician, the estimate cost would be around $250 - $350.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
