Based on the Model# provided, your TV does not have a color wheel. Could be one of the PCBs is bad, or even the panel. Have a TV technician look at it.

Good luck

In some models of LCD TVS; the backlight inverter will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, it can't be replaced. In this case; a panel replacement is the only repair.

Start with an examination of the power supply, burnt parts or puffed up filter caps---the set is not making it out of standby to on.

If you can see a dim image when you look at the screen at a sharp angle then you most likely have a faulty inverter board or faulty CCFL lamp/s.
Most likely faulty inverter board which supplies high voltage to the CCFL lamp/s.

First of all, look over the remote and see if there is a "sound only" button, or something to that effect. I know my Sharp TV has that. If not, try unplugging it for a bit then plugging it back in. Otherwise hopefully you're still under warranty. That's all I can think of.

Radio speakers maybe too loud to cause contact resistance to the LCD connector in the circuit. Contact resistance can go as high as 40,000 ohms up from 0.1 ohm. Disconnect and reconnect may reduce contact resistance back to 0.1 ohm.

On the right hand side of this television there are panel buttons. It appears that your son in law knocked the tv out of the correct input. Press the input button in order to cycle through the 5 inputs. Typically pressing the input button on the side panel of a television and pressing it again and again and again will make it change inputs. Universally the buttons on the tv panel function as follows: Channel up moves the cursor up. Channel down moves the cursor down. Volume + moves the cursor right. Volume - moves the cursor left.
Hope this helps

Speakers can cause problems with the correct display of video on TVs but usuall it only concerns direct view tv. Projectors should not have any problems or flat screens. I think you have a different problem Explain better what you mean by distortion in the JVC. Let me know and I will try to help you.

Check cables connection at the back.
If there is not or weak signal it depends either on cable or on devices connected (receiver, DVD etc.).
Try browsing sources using the Input/source button. Try swapping cables.
If you are using the internal TV tuner, then the antenna cable is usually the problem.
Work on cables and connections and let us know how it goes.

HDMI is audio and Video in the one cable, if your stereo has HDMI in and out you can run it from your box into your stereo then into your TV, but only if everything is supported by your componets, I would suggest, HDMI into your TV, then from your box, stereo or optical into your stereo, by just using RCA cables. ALSO remember with audio compontes, more is MORE, more cable better quality (not length but size)
