Television and Home Theater

     when my tv is turned off and turned back on, the picture is a green arc at the top and black on the rest of the screen. the green is rolling. if i turn the tv off and on a random number of times, it turns back to normal. leaving the tv off or on for some time makes no difference. any ideas on problem or fix? thanks for the help!

i have a pioneer vsx-1016txv, an hdtv (1080p), and two gaming systems. before i just ran the hdmi cords directly to the tv from the gaming systems and used an optical cable for the sound on each one. I was told that i can run my hdmi cables to the back of my stereo, then use another hdmi to go from the line out part of the stereo to the tv, and i was told that not only would i not need optical cords anymore but because the hdmi cables i have are so good it not only would give me sound but great sound, like 7.1 and everything. So, i did it, and i finally saw some results i saw video.

I have two problems.  I know the lamp needs replaced, but I don't want to do that if I can't fix the other problem.  The TV turns on, I have audio and of course (bad lamp) no video.  Then at about 30 seconds the TV shuts off.

Any suggestions?  Do I need to replace the lamp first?  Is the lamp causing the TV to turn off?

I don't have a lamp light on at the front of the TV.
