I've had this TV for a few years now and I love it. It still has a great picture but lately the image seems to zoom in and out. When a bright image is displayed the image gets large, and the edges fall off the screen. At its worst it can split the station logo in half. when the image is darker the size seems to return to normal. In the begining after the set warmed up it went away but now it don't. I tend to run the brightness and contrast settings lower than default so I don't think I'm pushing it too hard.

Re: Picture Zooms in and out
Check your b+ goin to the flyback, and see if the voltage changes durring picture changes. if this is too high or moves around alot, then you have more then normal then i would check your p/s. either or it could be a weak regulator. Also could be something else, i know that magnavox has a problem with this, and they have you replace 2 sm trasistors on bottom of board in the ABL line, i believe. I checked the mitz web site and they have nothing listed for this problem. might also want to check caps in p/s and 100uf on signal board while your in it.

This problems u are having it is not the causes by the tv,because ur tv it is a analoge CRT tv,don't have this functions zooming in or out or the problems just causes only 8% cutting off edges of the tv pictures only.If the problem it is happening to ur analoge tv it will have no vertical hold at all.The devices u are connected to the tv and using have zoomming in or out buttons or ajustment buttons of the sizes of the picture on the screen.Used the devices remotes controls to readjust ur zooming or pictures sizes adjutment.
If the image on screen is zoomed both in vertical and horizontal direction, your TVs power regulator inside it is faulty. [Overvoltage]. If it is zoomed in vertical direction only, that is only the height of the picture is zoomed, you can adjust it with the remote control button directly on going through menu and get in to the function menu. Normally all TV remote has a special button marked as "Zoom" which on pressing it once the picture get zoomed, again another press the picture gets wide and again an another press picture will come to normal mode. You should select normal mode to retify the problem.
This TV is NOT High Definition but the picture is as close to HD as you can get. It also has 1 S-Video and 1 Composite port which gives a GREAT picture! I have owned this TV for about 8 years and still love it!
Normallly, if the picture size button on the remote for the television does not achieve the desired affect, then, a cable box or a satelite box is where the change needs to be made. For example: A Motorola Cable box needs to be set up to go to a wide screen or zoom when an analog signal is detected. Some DishNetwork boxes have Size buttons on their remotes and also in their main menu. It's difficult to determine the repair without knowing the types of the peripherals. Hope this helps.
