Question about JVC AV-48WP30 48" Rear Projection Television

1 Answer

Warped image We were given a AV-48WP34 unit. The owners said they replaced two IPs a couple of weeks ago. Well, when I plugged it in and got a video source to it, the comments about convergence issues were a little off base. The image is distored. The edges and the sides are fine, but the center is crushed down. It resembles a ribbon, kinda. I went threw the convergence adjustments and nothing changed. I doubt this is the issue. Any ideas?

Re: Warped image

You definitely have a convergence problem based on the photo you provided. It looks as though someone reset the memory back to an uncorrected state or botched the job replacing the chips. Customer controls will not help you. You need to have a qualified technician address this problem. Good

If you have no video and its making a popping noise its mostlikely shorted convergence circuits. Contact and ask them to make you a kit for chirping sets.
