Can't read text on the Weather Network for example. Picture generally blurry.

    it's a 98 and certainly not worth spending money on. Is the focus control the potentiometer at the back of the tube?

The focus control is on the high voltage transformer. These Zeniths were common to have the CRT's fail and cause a blurry dark picture. If the focus control doesn't do much then your CRT is bad.

How old is the set? If picture is really very blurry, Try adjusting 'focus'. You can find this conttrol generally at the rear of the set. Otherwise,. if you know solid state electronics, Check the Focus control on the FBT. It is also possible that the CTR Base is faulty. Replacing this helps.

Is there any way I can clear up a blurry picture on this camera once the pic is already taken?

On TV shows, they can take a blurry picture and enhance it to crystal clarity. In real life, however, those kinds of miracles aren't possible. In a photo editing program like Photoshop Elements, you can bring up the sharpness a little but you eventually reach a point where the picture no longer looks like a normal picture. The slogan is "garbage in...garbage out"...meaning you can only do so much to what you have to work with.

Fuzzy Picture

Fuzzy is a funny word. I never use it to describe a picture problem. That because fuzzy can go too many different ways. There is snowy fuzzy, blurry fuzzy, grainy fuzzy, and demodulated fuzzy. If the set goes out of focus intermittently that has something to do with the focus ciruitry. If it goes grainy that is a front end problem, usually tuner related. The other types of fuzzy are generally associated with problems in video processing some where. So, which is it?

Oh, and BTW that unit has three small picture tubes in it, one red, one blue, and one green. It doesn't have a 'bulb'.

Blurry screen?

there are 3 things that will make your tv go blurry, the focus and screen control assembly , the high voltage splitter and the horizotal transformer and that is only if all three tubes are blurry.if only one tube is blurry, more than likely the tube itself is bad.
