Question about JVC AV-56WP74 56" Rear Projection HDTV-Ready Television
The TV worked fine one day and the next it had the red, blue, and green lines making the picture warped. I took off the front panel and adjusted as best I could and found that all the bulbs worked but only could adjust red and blue. I'm not sure what the problem really is since the green bulb works but can't be adjusted. I'm a noob at this but learn fast so any referance would be helpful.
This is caused by failing convergence ic's. They take the image from the three picture tubes and align them so that one picture is displayed not three. They are the two large ic's on the biggest heat sink in the front of the tv, but changing them can be tricky b/c resistors feeding voltage to those chips may be bad to. It is a simple repair to a qualified technician but a major headache to a novice. It is economical to repair but I would leave it to the pro's. Hope this helped.

Could you show a picture of the distended cover you mentioned?
Were the light blue lines you were referring to, diagonal, or truly horizontal?
