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
