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.
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.
