Its more than likely the CRT coolant if the picture quality is not very good. If the image appears 3 D thats another situation. Let me know if you need more assistance.

Not a clear picture


CRT projection televisions need periodic maintenance to maintain a clear picture. Typically, to maintain a sharp picture, they require cleaning and alignment every two or three years. If the television is being used in an environment where there is cigarette smoke or other smoke sources, the optics inside the television can become dirty and cause the picture to blur. Additionally, CRT focus and alignment wander over time, or physical CRT alignment can be knocked out if the set is bumped or dropped. All RCA CRT projection televisions have an "alignment" or "convergence" adjustment in their adjustment menus, which are fairly simple to use. The convergence feature is usually accessible from the main menu of the television. Check your User's Manual for the procedure to touch-up the convergence adjustment and see if you are able to achieve a sharper picture. If the optics in your set have not been cleaned for several years, or if it is in a smoky environment, the picture will be blurry and usually a brownish color, In any case, since the set is several years old at this point, it's likely due for a cleaning. This is best done by a technician, and mostly involves physical cleaning of internal lenses, the refractor mirror on the back of the chassis, and the back of the opaque display screen. An adjustment of CRT bias controls and individual CRT focus adjustments will bring further improvement in the image sharpness and clarity.

I don't have the remote, the picture in the TV does not cover the entire screen, it shows about 4to6 inches of emptyness at each side, what can I do to make the picture cover the hole screen?


To adjust the picture size on the television itself you would need a Sharp remote because there is a view mode button on it but there may be another way. If you are connecting a cable box or satellite tv receiver box to this television that remote should have an hd zoom # button or format button or aspect button that would adjust the picture size. The tv would have to be in the right input and the cable box or satellite tv receiver box would have to be set to the proper resolution according to what this tv is supposed to be able to display.

How do I adjust the HD quality for a crisper picture? I have tried Magic Focus, but need to know where the sharpness or contrast can be tweeked .


The magic focus function is to electronically align the red, green and blue beams. So all it can cure is colored ghosts. The contrast, brightness and sharpness adjustments are in the customer menu settings. With the remote just push menu and select video or picture adjustments. Those adjustments are in there.

Color


see if there is a "default" option, if not set everything back to the middle, if the colors are still off you sure its not the convergence?
most big screens allow you to change "color temperature" it's like a default adjustment for 3 different brightness levels.... ie...COOL, WARM picture will show obvious changes in brightness

Adjust picture


If it's a Magnavox, That's what your post is under, then good chance the picture tubes are getting a fungus growing inside the blue and green tubes. The sharpness will be lost as well. Need the tubes cleaned inside and then new fluid replaced. Take a minute to search 51MP392H magnavox, I answered this problem several times the past few days.
