Re: Picture Size

The problem is somewhere in the vertical circuitry. It could be something as simple as a leaky capacitor that builds up and throws the amplifier off bias. Or it could be the entire IC chip that runs the vertical.

In other words, there are a number of possibilities that will give you this symptom; the only way to find out is to have an expert tech do a diagnosis to find out the exact part. There are more than 1,000 parts associated with the vertical/horrizontal deflection system and anyone of them could be a part of this difficulty.

You could just replace the entire vertical module, but it would be very costly and, still, may not solve the problem.

So, it sort of depends on how badly you want to do it by yourself and how technically inclined you are. It is NOT, under normal circumstances, a home remedy. I does require some electronics know-how to fix.

Now, the really bad news: This set is very old. It is statistically very likely that if you do fix it another problem will pop up soon after it is repaired. It is just the nature of electronics when they get old. The fact that one part out of 2,000 or 3,000 has failed that it is highly likely that another part is ready to fail near the same time. You could be nursing the set for years to come and end up putting more time, money and sweat equity than it is worth. That is the biggest decision you face.
I looked to see if I could find you a service manual online, but did not find it anywhere. Also, I checked the Sams Photofacts page and they do not have this model - it is too old. Normally, they keep only about 8 years of data. You may be able to get one from Mitsubishi. If not, you would have to find a tech who knows how to trace the circuit from visual inspection - which most of them do, now days.
Sorry for the hard news.

Small picture

If a standard set and not a LCD etc it has a picture tube, width is a product of the high voltage circuit in that set---this is called the deflection circuit----deflects the picture top to bottom and also left to right, most likely a bad cap or if a wave like motion can be seen in the picture maybe power supply but that is rare.

Not knowing the age, size or value of the set if it is over 5 years old or the screen size is under 32 inches just replace it.

If no major part is bad the repair could exceed 100 dollars.

How do I change it from wide screen to regular? I have a black area above and below the picture.

You can set the picture size by remote control itself.

You can vide 480i format programmes in three picture sizes. 4:3, 16:9, and ZOOM
You can change the picture size by pressing the PICTURE SIZE button on the remote control.
4:3 Picutre size
To fill the screen, the top and bottom edges are extedted more widely, although the center of the picture remains near the former ratio.
If receiving a 4:3 programme, the image size is displayed in its originally formatted proportion.
16:9 picure size
This image displays the size of standard 16:9 with black bars at the top and bottom.
If receiving a 4:3 programme, the image is displayed with black bars at the top and bottom and stretched wider.

NOTE: If a fixed bar remains on the screen for a long period of time, the image can become parmanantly engrained in the screen and cause subtle but permanent ghost images. Never leave your TV for long periods of time while it is displaying these images.

Zoom picture size [for 16:9 formats]
The entire picture is uniformly enlarged --it is stretched the same amount both wider and taller (retains its original proportion). The right and left edges of the picture may be hidden.

Size of the picture decreased

If this only happens with your cable or satellite box this may be an adjustment in your box. So you may need to contact them and find out how to adjust the picture size. This tv may have a wide mode setting on the tv remote. Pushing this button may select full,wide,wide zoom or normal size. On many occasions the tv stations control the picture size. Good Luck

Picture Size

Normallly, if the format 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 when an analog signal is detected. It's difficult to determine the repair without knowing the hook up of the peripherals. Hope this helps.
