Hello,

I think you need to check the ballast. The ballast ignites the lamp. A defective ballast to cause your screen display become dull or dim.

So, you might also need to replace the ballast.

Lastly, power problem could cause this type of problem. When the power board is not supplying full current into other parts of the TV, this can cause the display to become dim. So it is also possible that low voltage circulation in the TV is the cause of the problem. Check the power supply board for any short or obviously bad capacitor or any other component on the power board.

But check check the ballast first, if that doesn't fix things, then check the power supply board.

Good luck.

I have a 52pfl7403d/27 and when turned on a square black box takes up 1/4 of the TV screen. I'm thinking backlight inverter. Any clues?


look instead in the menu under closed captions-----text feature is turned on in the set OR on a box if one is used.

If Text feature box will be near the middle of the screen, what do you have?

Zenith SL2773W problem


The dark rectangle appears because you have the closed captions on and set to TEXT. Closed captions set to CC1 puts the words on the screen and TEXT puts a black box on the screen. Go into the menu, navigate to the page with closed captions and set your captions to OFF.

The image of my optoma hd803 became inverted.


Go into menu settings, look for a menu item that has to do with screen size and orientation. You'll be looking for the option to rotate the image for mounting the projector upside down on a ceiling mount.

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

The convergence is out


The most likely cause is shorted convergence chips and possibly a few pico fuses.

No picture on Westinghouse W32701 LCD Model


Screen goes black, sound unaffected. Can be remedied by turning off and immediately back on, but it will do it again and again and again.
