Your #1 suspect: LCD inverter, which supplies white light to the screen.

Your #2 suspect: the switched power supply, specifically 24VDC lead that supplies power
to the LCD inverter.

Either way, enjoy your 40-in set while it lasts, since its soon to be heading for a TV repair service.

No picture just sound


on startup a television is subjected to severe inrush currents this sometimes results in a blown fuse in the psu stage most often at cold startup...this is the place to start...remove and test psu fuse...take precaution when working on tv as many high voltages exist sometimes even long after power is turned off...avoid the high voltagte thick red lead going into the tv tube or discharge if required the same applies to any high voltage reservoir capacitor/s in the psu stage

TV will not turn on. It makes a nonstop clicking noise.


Sounds to me like the high voltage power supply is attempting to fire off the metal halide lamp without success.

Intense white & coloured horizontal line on black background on startup


I wouldn't attempt as the capacitors on a tv store around 25000 volts this is more than enough to kill you and they keep there charge even when the tv is off. Either take it to a repair shop or put that money towards buying a new tv - Do not even attempt to open the tv. (It sounds like maybe a tube has gone or the electromagnet that makes the beam move vertically is gone.

Canon A75 No startup sound & display on LCD, rest of things works fine


Think it might be your batteries. 700mah batteries are pretty weak by today's standards (most are at least 2,500 mah these days). I'm guessing your batteries are several years old? If so, they're really only meant to have a usable shelf life of a few years, whether they are used or not. Recommend trying a new set of rechargeable batteries.
