CT-36SL14 powers on with clicking noise.


Sorry, but you've been had. From what you describe, it sounds like the set is going into high voltage shutdown. It does this if picture tube voltage goes over limits that might cause excess x-ray radiation, and the only way to clear the shutdown is to unplug the set. A number of things might be causing the problem, including a bad picture tube which would exceed the cost of a new TV. Without checking the set myself I couldn't suggest anything specific, and there are few repairs you would be able to try for yourself without the tools and some experience.

The only "solution" to this, I think, is to try to get your money back from the seller as the item was misrepresented, and apply it toward a set you can see working before you buy it.

42EDT41 colored snow/pixels


I have the same green dots that are seen especially when the bacground picture is dark or black. Mine does not seem to be changing when it warms up, and I also get it on my digital cable as well as on any DVD's I play. Please help with any advise. I think it was always there, but I assumed that a dgital cable upgrade would fix it - I should have known better...

Thanks a bunch in advance...

Green line down left side and geen snow


Horizontal or vertical bars on the screen could be from an ac line interference, adjacent magnetic field, bad input wire connections.....especially HDMI connector cables. A bad HDMI cable causes all kinds of unwanted picture interference. Check the conditon of all connection wires for proper fit and function. Keep in mind the method in which you connect your tv will result how the tv performs. As well this line problem could be a circuit issue too, requiring a technician to look at it.

Diagonal green lines on a green screen


It is possible that the electron-gun inside of the CRT is having an intermittant short. It is also possible that there is an intermitttant failure in the bias or drive circuits for the CRT electron-gun.

The TV service tech would have to run some tests to determine the actual fault, and then the failed components.

If the CRT is at fault, the set will not be worth to service.

Picture clarity


Sounds heat circuit related, and if under warranty you should notify them before you have to pay for the tuner or sync board.
