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.

Re: Picture size decreases and increases with non uniform...

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)

Is this a DLP or a conventional 3 tube rear projection?

If the lines are not actually in the picture but on the screen it may be if they are straight fine tape used around the inside edges of the screen---if in the actual picture a different story.

Philips magnavox 6P6030 W101 picture is too big and can't see the outer edge of the full picture

Not easy with a older set----look to see if a physical control exists in the set for Vertical size (picture too tall) and the adjustment may only exist in a hidden on screen menu.

Shuts off after 15 minutes

Most likely you have picture tube coolant leakage on the power board. Have an authorized Mitsubishi service shop take a close look.

Tv stuck on zoom


Thanks for using FixYa. Please check your cable box settings first. Sometimes the remotes have a picture size button on them, and the in-laws could have pressed that by accident. Check the TV settings, press Menu Button & then go to WINDOW/IMAGE SIZE. Now select normal size.

Also check the settings of the converter box (if you are using it). The boxes also have a peculiar problem: Unless users manually change settings from show to show, the picture from many stations either won’t fill the screen, or it will be so big that part of the picture is cut off by the edges of the screen. The solution is to press the “zoom” button on the remote that comes with the converter box. That will expand the picture so it fills the screen. If still the issue persists, then you’ll need to go to the service menu. To go to the service menu please start with the TV off and press mute > 1 > 8 > 2 > power the remote on. Now the TV will come on with the menu displayed and from there you can change the settings as required.

Please do rate the solution and revert for further assistance.

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.

Hd picture too wide

If you are using a cable box you need to look on your cable remote for HD ZOOM or you can try the # sign on the remote. This should change your screen size and get you taken care of.

Mitsubishi VS-4541 too much red

The set is old and the picture tubes are probably weak. you can pop off the front grill, remove the protective panel to expose the picture tube sockets. On the sockets are controls to increase or decrease the intensity of the colors. The red is on the left ,green center and blue right. Go to a B&W picture or turn the color off, then adjust for the best grey screen.
