Question about Philips 9P6040C 60" Rear Projection Television

2 Answers

Picture size decreases and increases with non uniform edges

On power up the picture is about one third the size of the actual screen size. The edges of the picture that is displayed are non uniform and almost have a rounded appearance. The picture displayed increases and decreases in size at random. After the set warms the picture gets larger and becomes more stable. However the full picture size is never achieved.

Common problem. If its warped but stationary I would agree its most likely the convergence chips.

If however it shrinks/expands its most likely the opt chip. You can get a repair kit from for this common problem. Other symptoms may be no audio/video but this problem typicaly happens after you encounter the 1st problem ( shrinking/expanding video)

    If you have any of the following problems you may want to check the site for a repair kit. Most of the issue below are fairly common with the older Magnavox projection sets. 

    Symptom: Screen shrinks and expands - may or may not correct itself after the TV warms up. After a few days, weeks, or months of having the shrinking/expanding problem you may loose all audio/video but the power light will remain lit!

    (Note: The below symptoms typicaly occurs after having the expanding/shrinking screen problem above)

    Symptom: No Audio or Video but power light is on

    Symptom: Audio works but no Video. Power light still work

    Symptom:  No Video. Audio is intermittent. Power light still works

    Sounds like a convergance IC problem, Either replace the convergence IC's or replace the convergance board.

Picture size

I found the user manual online, and the pictures in it are really helpful and make this make a lot more sense, but:
1. Press [SCREEN MODE], to switch the TV aspect ratio.
2. Press [SCREEN MODE] repeatedly until the normal screen displays.
NOTE: • Some programs may not offer all display mode options.
4:3 Programming
[Sidebar] Sidebar displays a 4:3 picture at its standard 4:3 size. Sidebars will be displayed on the right and left edges of the screen.
[Full] Full displays a 4:3 picture at a 16:9 size, with horizontal elongation necessary to fill the screen.
[Cinema] Cinema displays a 4:3 picture at a 16:9 size, with less horizontal elongation necessary to fill the screen because a little bit of the top and bottom edge of the screen will be cut off.
[Wide] Wide displays the center of the picture as original size and the outer sides of the picture will be elongated. The size of the picture will depend on the original signal.
16:9 Programming
[Full] A picture is displayed at 16:9 size as it is.
[Zoom] Zoom displays a 16:9 picture without changing its horizontal and vertical ratio, at its maximum size.
[Cinema] Cinema displays a 16:9 picture with vertical elongation.
[Expand] Expand displays a 16:9 picture with horizontal elongation

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.

How to enlarge a picture that is scanned or copied? When i scan or copy a picture it is too small and I want to enlarge it in order to view it better.


Open an image. Go to the Image Menu and select Image Size. This is where you can change an image’s resolution and print size (width and height). The following Image Size dialog box will appear:
Notethat the width and the height of the image as you view it on yourmonitor is not necessarily representative of the image’s actual widthand height—i.e., the size it would print out at (print size).Average monitor resolution is 72 dpi. If you view a 72 dpi image at100% in Photoshop, chances are that it will appear on your screen inits actual print size. However, this is not true when viewing a 300 dpiimage. A 300 dpi image viewed on-screen at 100% will be enormous. Don’tget tricked into believing that what you see on your monitor is whatyou’ll get when you print or place the image into another application.The best way to determine what your image’s actual print size will beis through the Image Size dialog box.
When the Resample Imagebox is checked, any changes you make to an image’s width or height willnot change the image’s resolution, and as such, any changes you make toan image’s resolution will not affect the image’s width and height.Keep in mind, however, when you increase width and height, orresolution, with the Resample Image box checked, you are adding pixelsto your image. These pixels don’t actually exist so Photoshop mustcreate them. As such, you will succeed only in degrading the quality ofyour image.
If you want to increase an image’swidth and height, or resolution, then uncheck the Resample Image box.Now any changes you make to the image’s width and height will changethe image’s resolution, and vice versa:
  • If you decrease resolution, the width and height will increase.
  • If you increase resolution, the width and height will decrease.
  • If you increase the width or height, the resolution will decrease.
  • If you decrease the width or height, the resolution will increase.
Thebest way to increase the width and height of a scanned image is to scanthe image in at a high resolution (about twice what your finalresolution should be), and with the Resample Image box unchecked, decrease the resolution. Once the image width and height is where you want it, you can then check the Resample Imagebox and type in the resolution you want if the resolution is too high.At this point, as long as you don’t increase resolution, or width andheight, your image quality will not suffer.

Picture to wide

This trouble symptom picture wide or"blooming", the picture becomes dim even with the brightness control full on,and there is an abnormal enlargement of picture or raster.Usually,the enlargement is uniform,but there may be some defocusing.In some circuits,the brightness control operatesin reverse(rotating the control for an increase in brightness produces a decrease) after reaching a critical point on the control. If the picture wide is not accompanied by insufficient width(a symptom of horizontal output failure) the probable cause is a high volatge circuit ony,particularly the HV rectifier and HV winding.Any circuit problem that reduces but does not completely eliminate the high-voltage output to the picture tube second anode can cause overscan. The most likely defects are leaking high-voltage capacitors,defective high voltge tube rectifiers,leaking high voltage leads,defects in high voltage circuit protective resistance,and shorted turns in high voltage winding of the flyback transformer.

Hope this may help you;

Screen is all shrunken and in one corner...Convergence Problem... i think

I had the same issue. The screen would shrink and then expand over and over. After thrity minutes it would correct itself. 
After a few months of doing this it just broke - no sound and no videe but the power light was still on. 

I searched these forums but did not find clear instructions or kits on how to fix it. I gave up and called in a repair tech. He fixed my TV in less than 30 minutes. 

To help others I documented the fix and created a repair kit and step by step quide on how to fix the problem. You can find it here.
