Question about Panasonic PT-52DL10 52" Rear Projection Television

2 Answers

Screen's color in black and white

I have a PT-52DL10 and it was working fine for a year. Last night, i was viewing a program and the picture started flickering to a black and white picture with a slight green tint. It flickers these colors and comes back to normal and repeats on and on and on in 3sec intervals. I had a service guy come out and he said its not the dlp lamp but he wasn't very knowledgeable on DLP RPTVs. Is there a board i can switch out? and what is the model number for that board? If i used a tech, how much would it cost me? This problem is driving me nuts!

Re: screen's color in black and white

Is there a "recall" section in the menu? or a picture reset?

Re: screen's color in black and white

Your color went out because the color wheelor generators not working. These are sofisticated sets and if I were you I would call a pro as you dont want a local guy who knows little about DLP sets to cause the problem to 10 fold. Contact 800-211-PANA see if they can help

I have a panasonic pt-60dl54, the sound works but green picture

Hi,Yes your problem sounds like the DMD board.This is how it works: Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens.You will need to replace the DMD board. Have a blessed one!

Spots on picture screen,color not correct

the picture tube has three color production units (bulbs) red, yellow and blue.....since these three colors can be combined to produce almost any color. as you have specified the red bulb might have damaged due to one of the following reasons.
1.continuous usage
2. keeping your tv in standby mode for a prolonged time.
the only thing you can do is call a technician and get your damaged part replaced.
remember please do not try to disassemble the unit yourself.

Won't Turn On

I just went through this issue. First, we replaced the bulb which did nothing.  Next, I swapped out the ballast assembly which did nothing.
Basically, the color wheel is not spinning up, preventing the lamp from firing.  One cannot buy just the color wheel, though.  You need the entire light engine which is about $2000.  Only, they are no longer available.
I may take this unit over to my shop and try whacking the color wheel and see if it will spin up.  If it does, then problem found.  If not, the set is landfill bound.

Color wheel bearing can make the noise you describe, and that will also cause color distortions.
