Question about Zenith H32G48S TV

1 Answer

Screen goes from blurry to clear to blurry

For about a year my Zenith 52" Large screen TV has had a blurry screen. When its first turned on the screen goes from clear to progressively blurry. The last 2 months it starts out blurry, after about 30 minutes it goes clear. It usually stays clear for 30-45 minutes then gradually gets so blurry it is not even watchable. If its left off a couple of days or for several hours, it will stay clear longer. Can anyone help?

Re: Screen goes from blurry to clear to blurry

The first thing to check is for loose conections,the problem is related to the high voltage but it can start in the main board with one component loose,when the high voltage is developed it goes to what is call the distributor block,a lot of sets have the focus and screen controls coming out of this block for each picture tube,this block might be bad but before we go to him we need to check everything is solid in the main board.If you are familiar with electronics you can remove the back cover and tap the chassis with a wooden or rubber handle to see if the set reacts,if it does you need to be atentive what area makes it react and flip the board to do some resoldering,If you are not too familiar with tv service you need the assistance from a servicer.Let Us know how it goes or if you need more information.

Zenith 32" TV picture is larger than the TV screen size.

Adjust the Aspect ratio. The manual will tell you how.

My tv is blurry. how do i get it to clear up? I

CRT tv's have a FOCUS adjustment on the flyback transformer. There may also be a "screen" adjustment on it, but you DO NOT want to turn that one.

You would have to open the tv, and take an INSULATED TOOL and turn the little adjustment labeled FOCUS or F on the flyback transformer, which is the large (usually black) thing that makes the high voltage for the CRT. It can easily be found by tracing the large red wire that has a suction cup at the top of the tube in the back. This wire goes to the top of the flyback. the focus is usually on the side of the flyback.


You must be very careful when doing this. Use a mirror to see the front of the screen while adjusting, don't reach around! Since this is the part of the TV that has LETHAL voltages you must be VERY careful not to touch anything else, since this must be done with te set turned on and warmed up.

Zenith TV has a big black box in the middle of the screen.

After reading other postings, we figured out that it was the caption box, went to menu and turned it off.
Thanks for the great site, we wouldn't have figured it out without it !

Blurry text on 27-inch Zenith "Sentry 2"

I have had this problem before and restarting the reciever fixed it. Just push the red button under the front panel of your reciever, or unplug the reciever for a minute or so.

How to clean the screen

Philips has Projection tv, screen cleaning fluid and a soft brush also to clean your set. You can buy this in most stores like Walmart or online. And remember that your screen have grooves in it so follow the patterns. I think most goes up and down. Hope this helps!
