Question about JVC AV-48WP74 48" Rear Projection HDTV-Ready Television
There are shadowing and waving effects on the pictures of my JVC 48W30 CRT projection tv. i checked the convergence button on the menu and saw green + and blue+ only and they're apart form each other, tried to move it manually and only the right side where aligned and the rest can't be move horizontally, vertically yes it can be move but not horizontally.
can anybody help me solb my problem?
Here are some of the most common symptoms and example photos of a convergence problem
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and picture shadowing and waving pictures - 2c07611.pngeplaced. This is a common problem.
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

picture on tv started waving in & out
normally this problem is due to main filter capacitor failure in tv which is located in power supply.it becomes dry after few years
you can also check for normal voltage at input to your home.
hope this will help
