You can try to clean the mirror and lenses. or try to adjust the focus for each CRT(picture tube). also could be a convergence alignment issue. check the main menu for convergence alignment feature.

Blurry picture


Generally a blurry picture on a projection tv is a convergence board failure. This usually requires the replacement of the STK voltage regulators on that board plus any associated burnt or open resistors near that area.

The picture started to get blurry, after being turned on for 10 minutes would clear up, now just stays blurry and almost no picture at all.


Hi

Thanks for using FixYa. To reset the picture you’ll need to reset all the Video menu options to their original factory setting for which you’ll need to follow this step-by-step procedure---

Press the Menu button and then use up or down arrow button to select the Video menu. Now press the right arrow button and then use up or down arrow button to select Video Reset then press the right arrow button to reset the Video menu options to original values.

If still the problem persists, then you’ll need to check for local interference such as an electrical appliance or power tool and also check the antenna. If required change the direction of the antenna.

To resolve the issue of Blurry Screen, first check whether all the cables from your dish network are fine and connected firmly. If yes then you'll need to pull off the front of the TV, behind the speaker grill there would be a panel. Remove the panel and check for a black box hanging over there. It has 6 controls on it, 3 are marked as focus and 3 as screen. You'll need to adjust the screen. If you turn these too high you can damage a tube. So we are doing real small adjustments. Turn the color off on the TV and adjust the red, blue & green controls up till you get a fine picture. Also adjust the focus until you get a clear picture.

And, if it doesn't resolve your issue then it is an intermittent blue picture tube, a bad blue driver transistor on the CRT board, a bad connection on the blue CRT board, or a problem in the RGB coming from the video jungle IC. A set this age, most likely will run about 300-500 bucks to have this problem fixed, unless it is the picture tube.

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

The screen looks out of focus and the top and botton bend inward.


Remove front bottom panel behind it is a small black control box top controls are focus controls for R/G/B and Bottom 3 controls are your screen drives adjust one at a time turn off G/B adjust red first,then Do Green and Blue fter adjusting focu to each tube leave them set then adjust screen drive turn color off adjust RGB for a Black and white picture get as close as you can then turn color back If after doing this you still have blurry looking picture look down into Tubes you should be able to see picture clearly in each one if you cannot see picture then projection Fluid need to be changed out.

Blurry tv


there is a focus control in the front of the set behind the front grill there is a door in the middle attached by screws take this off and it should be right behind it. There are six controls on a little box one row says focus and the other says screen don't adjust the screen controls. In some cases these are in the back of the set.

BLURRY PICTURE I need to adjust the convergence board, HOW?if I need to repair the board with a repair kit does these kit work?how can I access this board,I have electronic as well as electric experience...


If you are able to do this, the switches woud be in the back of tv under the panel. Some tv's like most newer tv's are not adjustable except under main menu for color, tint, contrast and that is it.
This is when the convergance board needs to be replaced.
