Didn't see the original question or follow-up, but the answer is no -- If the hyper module is failing and causing the wavy or line squiggles it will be apparent on ALL outputs to some degree and continue to get worse until the high ESR (equivilent series resistance) of those failing caps cause the chip sets to eventually fail then it will be nearly impossible to repair the module.

Most DVD players are connected to one of the rear audio/video inputs--hook to that input and select it on the TV--then hit play and if connected correctly you will see the movie.

Terminals and Connections Dual HDMI digital inputs with HDCP (High Definition Content Protection) offer an uncompressed solution to the transmission and display of high definition video and audio content. All JVC HD-ILA TVs also include dual auto sensing component video inputs, assuring the best possible picture quality whether a viewer is using DTV, D-VHS or DVD, and three S-Video (two rear, one front) inputs and four AV inputs (three rear, one front).

HDMI is a new standard digital connection between A/V devices, such as a set-top box, DVD player or A/V receiver, and a digital television. HDMI offers exceptional video and audio quality with a single quick-disconnect connector. It supports multi-channel digital audio transmissions and component video color spacing for true rendering of HD video.
We carry a full line of high-performance HDMI cables. See them here...
Audio Features The JVC BBE High Definition audio system with Advanced HyperSurround and Active Hyper Bass includes two direct-drive speakers mounted underneath the screen for rich, expansive sound that fills your home theater or TV room.

I have an onn 42 inck flatscreen tv and since last night have lost all colour on screen,,,tried cable and scart all seem ok,,any ideas


Hi.

If the problem happens using different input and devices, then it is either the terminal circuit (input/output connectors) or the processing unit in main board. The terminals are unlikely the culprit if problem concerns different inputs.

I imagine that the picture is not properly B&W (gray-shades) but some kind of reddish, bluish or greenish picture as the LCD will process picture using RGB (red green blue) channels instead of CYMK (cyan yellow magenta black) like CRT TVs.

Test the TV using an external aerial. You will notice if the channels have the wrong color even from static.

Use different inputs, different cables and different devices. beware of SCART cables, the SCART contacts are very easy to break. A defective cable will loose picture. Better testing using AV cables and component cables. AV cables are red/white for sound and yellow for video. If the two-wired yellow cable does not work, then the TV is faulty.
Other test can be done using component cables. Component cables send the three red-green-blue signals on different cables, hence testing is simple. Test swapping cables and see if TV tone stays the same if color tone changes the problem were the cables. Test also using at least two different devices (e.g. one DVD player and one TV receiver or a playstation).

If you find that the TV is defective call the manufacturer at the number listed on manual. If the problem is that one or more RGB channels do not work the TV main controller board must be replaced.

Regards.

Mitsubishi rearTV has intermittent wavy lines running throughout


Do you have anything to test it in 1080i? Does it do it on all connections or just one? I had a similar problem with my TV that turned out to be a bad input board. Mine would only display 1080i through the Component connections. All others would show pink and green wavy lines. It cost me around 500 to fix it. Unplug the TV. Remove the back cover for the TV. Using a NON-metal object, or gloves, wiggle the input board (that has all the video connections on it) slowly back and forth and see if the problem comes and goes. You will have to have someone watching for you. If something is loose on that board, the problem should show itself. Narrowing down the problem will probably save you money on repair bills.

Im trying to set up my tv, it was given to me as a gift, my uncle was using it it works i can change the channels but when i try to work my dvd player with it, only the audio comes on the screen stays...


Hi,
Please few things...
1- Make sure audio and video wires are hooked correctly in AV input of tv and you selected that AV input in tv with its remote.
2- Also check your dvd has not been set on progressive mode if you hook dvd player through yellow-red-white wires with tv.
3- if dvd player is set on progressive mode, then hook it with tv by component video input, red-green-blue for video and red-white for audio.
Hope this info will solve your problem.
Thanks.

Toshiba TN55X Convergence problem.


You brought up an issue that we hadn't considered. Shortly after hooking up our TV to the receiver with a composite video, our convergence which wacko. My hubby replaced the 2 ICs, but now our power button just flashes red, with no picture. Not sure if new ICs are faulty or if it's another issue. He will replace old ICs to see if problem still exists with turning on the tube. And he'll try disconnecting the video signal to see if problem exists.

Ouch.. may have to consider another tv thanks to new technology ??????

Good luck solving your problem.
