I have a 05 jvc tv 32 inch . I lost my remote temporarily-used the menu on the actual TV to set a timer for the TV to go OFF-turned it on this AM and now i have half of my screen filled with this overlay ....

Try Reseting It Unplug It For 30 Seconds And Then Release And Plug It Back In Once You Go To Turn It On Hold The On/off For 10 Seconds and Then Release. This Will Hopefully Restore The Factory Setting And You Can Determine If Its A User Setting Or Hardware Problem.

It sounds like the closed captioning background.

Press Menu on the remote
Press Up or Down, Ch + or C- to get to Closed Caption
Press right side button or Vol+ and Mode will be highlighted
Press right button or Vol+ until it says Off on the right hand side of the Menu
Press exit and that should do it.

Hope this helps.

Color switches to b/w, then a click, then color, then b/w, click, etc.

Good day.

I think your problem is with the crt circuit. It is the one on the rear of your picture tube. Some loose connections may occured in there. Also, check if the flyback is arching. Sometimes, the voltage on the flybach itself causes this.

Your model has a maximum resolution of 720p. What you might want to do is make sure that both your cable/sat box and game stations are outputting at no more than 720 resolution. It's easy to assume that all HDTVs may accept a higher signal, and while they might, some of the scene changes or handshakes may make that operation cause the symptoms you describe.

The black box your are seeing on the screen is the box to display text. It is listed under your "cc" closed captioning setting as T1, T2 etc. Go into your closed captioning and shut off the text. You can still leave closed captioning on or off. The text system was never really used but they put it on all of the TV's.

No picture with DVD input

Your going to need the original remote to switch back to AV input in the menu. It should explain in the owners manual how this is done. If you do not have that or cannot find the manual go to a search engine and look up emersom dowmloads it will show up as I think PS dont forget to rate this.
