While it is true JVC tubes rarely fail, they can give trouble.
Another possible solution is bad screen / focus block......
Remove lower front grill panel and access board...Check for
smooth adjustment of RGB screen and focus.....let me know....T..

The only way to do that is by eye. To Adjust the screen controls the best thing to do is turn them all down then slowly adjust one up until you get retrace lines (arched lines across the tv) then turn it down until the lines re not visible then go about 1/4 turn more, repeat this for the 2 remaining colors, after that its just done to eye for the best color. if you are still having trouble getting the color right you can go in the menu to the video settings and turn the color all the way down then you will have a black and white picture and you can adjust for a perfect black and white picture then turn the color back up in the menu.
As for the focus controls its best done by covering 2 of the tubes so you only have one color on the screen then adjusting to the best looking focus for that color. then repeat this for the other 2 tubes.
If you need more help or clarification please let me know

I understand what you are saying, however the devil is in the details in reference to your problem. Let me explain, DLP Televisions use what is called "Color Wheel Technology". A wheel made up of primary and secondary colors spin at a synchronized rate with the Luminance Video signal and this along with the changing of the mirrors of the DLP processor creates the color that you see on the screen (This is a high level description, but it covers what is happening). Now what you are experiencing can happen if the sync between the signal to the color wheel and the DLP processor is off center, if the color wheel is out of alignment, or if the signal to the DLP is drifting. The bulb "light" is working but something happened to interfere with the sync between the color wheel and the DLP processor. I would suggest getting this looked at by a DLP qualified TV technician, because of the nature of this problem. In addition I would request that you have the technician do a certified alignment after the problem is taken care of.
I hope this helps,

you need to replace the convergence ICs and associated resistors you can get the repair kit at the following link for your model which contains the two ICs and all the feed resistors plus step by step instructions with detailed photos how to do the repair. Heres the link to the kit for your model.

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 should be replaced. 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.

2. here is Movie Maker 2.6
MM2.6 has the features to fully edit and produce a video, but it doesn't have the importing feature of MM2.1. For that, you can use the import wizard in the Windows Live Suite. MM2.6 works well with the Pixelan Spice FX6 packages of extras and Wizards, and you can setup other custom effects and transitions to work with it.
I've copied MM1 and MM2.1 from my XP system and MM6 from my Vista system, registered the DLLs and they are working well. But I haven't yet added many of the thousands of extra 3rd party special effects and transitions that are on my XP and Vista computers.
It turns out installing MM2.6 also resolved some Issues I experienced with MM2.1 in Windows 7. It's not surprising as they are very similar with one made for XP and the other for Vista. The Windows 7 system is closer to Vista.
3.Now Importing a Video
In addition to the newest version of Movie Maker, the Windows Live Suite includes a video import wizard that works with a mini-DV or digital8 camcorder connected by FireWire. MM1 and MM2.1 in Windows 7 also capture video from my mini-DV camcorder, when connected by FireWire.
Imported video clips can be browsed in the folders of the Windows Live Photo Gallery or imported into the collections of the classic versions of Movie Maker.
Starting with no version of Movie Maker in Windows 7, I'm now running with five of them.
hope this helps you do vote if it helps you in this regard
