It depends on your model #, However, here's one set of diagnostics that may help. If you could post the model # it would be a little easier to get the exact answer.

Also, Check the Lamp Door, make sure the Latch is seated correctly and securely, if it's not, you can get the same result, no image. Hope this helps

TV turns on with a green screen with curved horizontal lines.


It seems you may have a serious problem with your video board. That's why you are getting those symptoms. It's better if you replace it asap!

Screen flashes green a couple times then shuts off


you need a new green CRT. The lines were retrace lines which are the first sign of a tube developing a short eventually the green will short completely and cause the set to shutdown.

Green lines on screen


That symptom is caused by a bad dmd board. This will help: make sure you use all digits of model number when you order or lookup parts. This is located on a sticker on the side of your set. Also, you can price "rebuilt" light engine or dmd assy. and check for core value of your defective one. Good luck, Russmann.

Green lines on my Sony projection


Those are called retrace lines and they are the result of the blanking pulse not having the desired effect. This could denote a problem in the Horizontal section of the TV. In this case the green gun is not being turned off as it goes back to the left side of the screen.

Horizontal Lines


The unit most likely has a short in the horizontal section and would require repair by a service center. Go here to find a JVC repair center in your area http://maps.jvc.com/cAscList/
