Question about Toshiba 42HDX82 42" Rear Projection HDTV-Ready Television

1 Answer

Picture on 42HDX82 vertically stretchs after about 10 mins



I have had the 42HDX82 for about 4-5 years now, it has been powered off for 2 years and recently powered back on.  When using touch focus, it seems to consistantly fail on the "blue" horizontal bar.  Also, after running for 10 mins or so, the picture on the screen starts to stretch vertically, and gets worse as time progresses.  Does not "roll" vertically, but stretches to the point of not being able to watch the program.  When it is stretched out, it is also displaying "white" horizontal line randomly.


Any help would be appreciated.  I have no issues replacing ICs or boards.


It also has a low buzz when plugged into the wall.

    Picture drifts down the screen as the set heats up. I've taken the front and back panels off of the set and if it gets enough ventilation, the set will migrate back to viewable, if it's cool enough.

    But when I put the panels back on the set, it drifts back down. Argh. I thought about installing a fan inside the set but I don't know what's heating up. It's like the mirror in the set is warping as it heats up.

    Turning off the set for a short period restores the picture, but it quickly warps again unless I turn it off for a longer period.

The text along the sides of the tv screen are not completely in view

you need to change the 'zoom' on the tv by the remote.
Normal mode frames the 4:3 video to the 16:9 picture area by displaying it in its original aspect ratio, with vertical gray or black bars on both sides of the screen. The disadvantage of this method is the fact that the image is small by virtue of not using the entire width of the screen. This is also known as the 4:3 mode.
Full mode Full mode horizontally stretches the 4:3 video evenly across the entire width of the screen. This is the proper mode to display anamorphic video. If used for standard aspect ratio video, everything on the screen will appear wider than normal. Contrast this with anamorphic video displayed without processing on a 4:3 display, in which people on the screen will appear taller than normal. This is also known as the 16:9 mode.
Zoom mode Zoom mode evenly stretches the picture both horizontally and vertically, until the picture fills the entire width of the screen. This crops out the top and bottom of the picture. This mode is used for letterboxed and open matte video.
14:9 mode Main article: 14:9
In 14:9 mode, the picture is magnified more than in Normal mode, but less than in Zoom mode, while retaining the original aspect ratio.
Wide Zoom mode Wide Zoom mode, also called Just mode, Horizon, or Smart Stretch, progressively stretches the picture horizontally, less in the middle and more on the edges. This allows normal aspect ratio video to be displayed across the entire width of the screen, with minimal cropping, and with much less of the unpleasing visual stretching effect of Full mode.

Picture is stretched on wide screen a circle looks egg shape

This is an issue because most television programming is produced in a 4:3 aspect ratio. The minority of programming is high definition, which is produced in a 16:9 aspect ratio. Because televisions are made in either a standard (4:3) or widescreen (16:9) format, there is always a conflict with an image being stretched vertically or horizontally. In the case of widescreen televisions, the stretching is horizontal.
Picture Modes
Luckily, most if not all widescreen televisions have a picture mode that allows the user to toggle between a wide (16:9) and standard (4:3) mode. This means that a person can watch non-HD programming in the 4:3 picture mode, and then go to widescreen when watching HD programming. Some TVs have a picture mode that will automatically adjust to the correct aspect ratio. Other people will watch all programming in the wide picture mode, and learn to adjust to watching a stretched picture.
A stretched picture is when a 4:3 image is pulled on the sides to fill the entire screen. People and images end up looking fatter/wider and shorter.
So, what's the big deal?
Some people don't like a 4:3 picture stretched or distorted because it does reduce the overall visual and picture quality. Some people don't like the bars on the side of the screen when a widescreen is in a standard (4:3) picture mode because it looks different.
There is no fix-all solution for this issue, unless you own a TV that will automatically adjust to the intended aspect ratio. The stretching of the picture is a side-effect, the price we are paying for the better resolution that is digital and high definition. This is definitely something to consider when buying a television, but keep in mind that there is no right or wrong within this issue. It is just the way it is, and there is no way around it unless you buy a 4:3 aspect ratio television.
Hope these lines will clear the issue, if so do rate the solution

Needs vertical height adjustment

Is the picture stretched or shrinking and is it distorted or have lines? There are no vertical Height adjustment the circuit is prest and there is likely a problem in the vertical o/p circuit.
The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical.

Usually this is an indication of a failing capacitor in the vertical circuit. Have those been checked? I would look for 100ufd caps in the vertical circuit. Check with the tech.
