    I was wondering if there is a solution to fix my tv. The screen looks to red and very bright and sometimes the picture on a person faces fades into a grey color. I was just wondering if there is something I can fix my picture. Do I need new lamps?

    When I watch a show the TV picture has a red/purplish tint to it. When I shut off the the signal to the TV the picture is Black but with an erie red glow in it. I have never cleaned/aligned or done anything to the TV in 6 years. Will the color balance suggestion correct my problem?

You can turn up the Screen controls in back of set. Look for the focus block that has 6 controls on it. 3 are for the screen and 3 for the focus, in each color Red, Blue, Green. need to turn evenly to keep color balanced. On set turn color all the way down and then get a good black and white picture.

I have a magnavox 55 inch screen model nu is 6p5440w102. Picture is dark tried to lighten but wont brighten up anymore.
This is an older set------with back off you will see 3 large black cylinders with lens---these are the red, green and blue picture tubes.

Clean the lens with a lens cloth or paper towel with glass cleaner sprayed on the towel.

Annual cleaning of them is suggested as dust or dirty lens will cut down the brightness---this happens gradually over time and will make the picture darker and somewhat dull looking.

I do it with set on but you should UNPLUG SET and just look to see if dust on lens.

Simple and takes only a few minutes.

Let me know what happens.

HI I HAVE A PHILIPS MAGNAVOX TV THE PICTURE IS DARK ,IT.S KIND A HARD TO SEE SOMETIME .WHAT CAN BE DONE ABOUT IT . PLEASE HELP. .
If this is an older rear projection TV as the model number indicates, you can unplug and remove back cover.

Inside you will see three large round black lens---these are for the 3 picture tubes: Clean all the dust and dirt off of them with either a lens cloth or a paper towel with glass cleaner sprayed on the towel.

The lens are the light source for your picture and if dusty the picture will gradually become darker and some what blurry looking.

hope this helps you.

Picture on tv is dark panasonic mod pt47wx42
IT may be if the set has not been "serviced" in a while a cleaning issue. If picture got gradually darker try something easy first.

Unplug set and remove back cover.

Locate the three large black lens in set based on model number, use either a lens cloth or a paper towel with glass cleaner sprayed on it and clean all three lens.

The lens are the light source for your picture and if dusty the picture will be darker and duller looking than it should be.

If this is your problem it is a good idea to clean the lens at least one time a year.

Let me know if it works OR IF YOU HAVE QUESTIONS.

The tv seems to be very dark when a low lit image of a movie or tv program comes on. We have the brightnes on at full level. What could the poblem be?
The simple thing to check if the set has not been "serviced" for some years is dust.

With the back cover removed you will see three large black lens---they are the light source (red,green,blue) for your picture.

If the lens are dusty the picture will be darker and duller looking.

Clean with a lens cloth or a paper towel with glass clean sprayed on the towel.

If this told you something you did not know, rate this solution as very helpful as I do this here for free.

I would say your small signal module is bad. This is the board with the convergence ICs. Have a tech or yourself pull the board out and replace the ICs and some resistors. Checkout TVREPAIRKITS.com. They will have your model and its symptoms. Hope to guide you in the right direction!

I have a philips magnavox 60 inch model 9p6034c103 dark pic
Sounds like a lamp, but its free to open the back and clean the 3 color lenses and the big mirrior that will be directly behind your head.

Taken from the service manual:

2c) Using denatured alcohol on a cloth made of 100% cotton or a lens cleaning tissue, gently clean the Celement (fisheye) lens, coupler and the CRT faceplate..

Caution: Do not use soap or detergent type substances to clean the coupler and its related assemblies. assemblies must be completely dry prior to reassembly

ALSO: I have heard that a bacteria grows in the color fluid and coats the lenses. the fluid is VERY Poisonous, so please please dont dont clean the inside without research and reading the service manual!!! I've read posts where unknowning people opened them and it poured out.

Manual Library you should find all you need here:

How do I get Hitachi HDTV to find channels with an antenna? When I do a channel scan, it doesn't seem to find any channels. I have a brand new RCA antenna which works on my LG flat screen TV. I have tried it connect to both antenna A and B plugs and set the mode fo those antennas afterward. But, I always get fuzz on every channel.
