When your TV cuts off, does just the video cut off or do you lose all power? Does the power light stay on? If the power light goes out, I would suspect a bad solder connection in the power supply, or maybe a defective capacitor or two in the regulation circuits. If just the video is going to black screen, it could be your picture tube getting weak and the cathode current monitoring circuit is kicking in preventing you from seeing a sub-par picture. Sometimes this can be temporarily adjusted out by a very small amount of tweaking of the screen control located on the CRT drive board, but it is easy to get a shock and hurt yourself if you're not familar with the set. The CRT can sometimes be restored for a bit more life with a CRT tester/rejuvinator that the service Tech has access to if that is what is causing your symptoms.

You may have a bad port on the back of the receiver, a cut or disconnected wire somewhere on that side of the system or a bad diplexer if the system is not straight wired to TV2.
The easiest way to verify whether the port on the receiver is bad is to connect that line directly to TV 1 off the back of the receiver. Remember to place TV one on the CHANNEL TO CHECK IF IT IS GOOD. If you have picture then you have a bad diplexer.

Hope this helps. Thanks for using Fix Ya.

Sound and Volume trouble

I bought my Insignia 32" LCD in November 2007 - same problem. I figured out that if you press the "input" button on your remote select any of the other options "component 1, composite 1, etc.. that you're TV isn't on -then press "input" again and go back to the component that you're TV plays on - you'll have volume when you go back every time. I've gotten so used to doing it now that it's become habit. 9 times out of 10 I have to do it.
