Is the tv an lcd or a crt? and how are you connecting it with composite (red white and yellow) component (red blue green white red) or hdmi? if through composite or component is the ps3 set on the right connection? if through hdmi is your tv HDCP compliant? if not than it prob won't work till you do the firmware updates on your ps3 via a broadband connection. if it still does not work than you won't be able to connect it to that tv only to a tv (and surprise surpirse all sony lcds are HDCP compliant) that is HDCP. it normally says in the instruction manual. Unfortunatly HDMI connection is not the godsend they said it would be. if the device does not immediatly talk to what you are pluggin it into than you are going to have problems

There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

This indicates that the TV somehow went into service mode, and the colors on your screen are a test pattern. There are a couple things that we can try to fix the issue. The first, is to try and reset the EPROM in the TV. To do this, remove the power cord from the wall, then press and hold the power button on the TV itself (not the remote) for 20 seconds. Then plug the set back in and power it up. If this does not fix the issue, the last thing we can try on a user level, is to use the TV remote, and press Cursor Arrows UP then Down, and unplug power. Then plug it back in. If this does not cure the issue, then this indicates a failure in the TV's EPROM which is what runs this Test/Service Mode, and there are no resets or adjustments you can perform to fix this. It is actually a fault in the component that generates this test, and the set would require service. There is nothing you can do that would enter the Service/Test Mode as a user, so this likely occurred due to hardware failure. If your TV is still under warranty you can contact JVC from their service page for repairs below. I hope this helps! - Joe JVC Official Service Providers site Purchase genuine JVC parts and...

Look for the manual of your Universal Remote and find the code assigned to your TV.. If no code, follor proper procedure for "no code available!"

The first step in troubleshooting this would be to perform a reset on the TV. You can do this by unplugging it from power for a couple of hours. Once you've done this, plug it back in and power it on and see if any issues persist.

If there is audio but no video you may be experiencing processor failure and some additional troubleshooting is going to be needed.

If there's no video or audio, chances are something caused the TV to short out somewhere. Most of the time the culprit is the actual power supply itself. The repairs on these aren't too difficult or pricey and if the TV is still under warranty you should be able to get it fixed for free.

Nope sorry this does sound like your control board is naffed and needs replacing , it sees the avi as no rf input is needed but will not switch to if to give you vision chroma and sound .

good thinking on your part

1. Hold [menu] and [vol-] button on the side of the TV
2. while holding these, press the [power] button on the side of TV (NOT remote)
3. blue light comes ON and stays ON
4. wait 10 seconds then let go of [menu] and [vol-]
5. wait another 30 seconds and some type of picture should appear

I think this is right. I got it from the JVC call centers guys so sorry if I missed or messed up a step.

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
