Stand-by LED blinks-no picture or sound

I was watching tv when i heard a noise eminate from the television. When I pressed the remote "on", the stand-by LED blinks and I hear a relay "click" sound, but the tv has no picture nor sound. No smoke. The unit has operated flawlessly for the past 8 years. The picture was perfect when the problem occured.

The symptom is usually caused by a breakdown in the power supply circuit. in most modern receivers (transistorized and/or ic), it may also be caused by a breakdown in the horizontal deflection circuits (hor. oscillator, pre-drive, or drive circuits). supply voltages for the tuner, video if,sound if, and vertical output are usually supplied by the horizontal output circuit. but if you doesnt know anything about these stuffs, better bring it to a qualified service tecnhician

Your Panasonic TV's power light blinks when you power it off or on, or put it in Stand-by mode. ... Press the "Power" button again to set the TV to operate in Stand-by mode. The Power LED Indicator should illuminate as a solid red color. Press the "Power" button on the remote control to bring the TV out of Stand-by mode.

Count the number of blinks. Now, Google your make and model with the words blink codes added to the end. This will show you links to sites that will tell you what the blink code means and the problem with your set. The blink code is the sets way of telling the service man what is wrong. From the sound of it, you have a bad capacitor.
