You are going to have to have the convergence IC's replaced, the only way to correct this I'm afraid. Good Luck

I have a green and red shadow on the words. It appears towards the top and bottom of the screen.


Hello,

It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergence select that and wait a minute the TV will adjust itself and give you a clear picture.
If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the cursor (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It takes time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture.
You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of synch.
RPTV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.

You can pay somebody to do it, but may cost you like 100.00 or do it yourself, it is very easy just tedious and time consuming. If you have the auto convergence than your golden because this is the easiest way to "reset" the TV.

Since it is 4-5 years old it's a 50-50 chance that the TV has the auto feature. Good luck and if you still have the owners manual, I would read up on the convergence section in the manual.

So you should do a convergence about twice a year to make sure nothing is out of whack.Please run the convergence feature on your TV. Its giving you duble image because the red, green, and blue guns are disaligned. By running convergence it will realign the guns properly. You need to run the convergence feature at leat onece a week. Please note this is only for CRT rear projection tv's and I assumed it was. If it is an LCD rear projection, then there's nothing you can do to fix such thing, but call a repair person. But if doing the convergence doesn't fix the problem, you need to call a repair person. But I hope you won't have to. Please refere to your tv's manual on how to do converegence and how to overlap the crosses because every CRT projection tv is different.
Good luck

Hi. My Sony Videoscope XBR's Convergence Allignment


I happen to share this same problem. The alignment of the gridlines on the standard convergence panel are completely abnormal, and if I attempt to auto-adjust the TV, it flashes different colors on the sides of the screen , and then turns off the convergence settings.

What is your Chassis # ? And convergence problems can be some of the most hard to realign. You may need to replace amps.
