Was given a d52w15 has picture, but it is red green and blue

this tv does not have bulb or lamp it has 3 picture tubes red,green and blue

For CRT projection TV's, this indicates that the Green picture tube is burned (warn out). The less green that strikes the screen, the more redish the image will look. You will need to find an old school TV repair shop that knows how to replace picture tubes.
In the case of a DLP style TV, the color wheel needs replacing.

If the picture is blue only and there is no red or green, you have either colour gun failures or if you are trying to watch a picture from a component source there maybe something wrong with the red and green cable feeds. Try watching a DVD using a single composite video feed (usually a yellow RCA plug). If this unit has an internal tuner (either analogue or digital) and you still only see blue broadcasts then you have a problem. Whether this unit is an LCD or CRT rear projection TV the repairs will probably be expensive. Ultimately, it is not a user repairable device and needs a qualified Sony tech to undertake the work.

1.) It means the Glycol in the blue tube is bad--usually contaminated by bacteria--each of the 3 picture tubes has a sealed area between the face of the tube and the lens above.

2.) If you see a picture in Green and RED but blue looks like a floodlight--the blue tube would have to be removed, drained, and the area with the Glycol washed out---new glycol added and the tube resealed and installed back into the set.

3.) This is a fairly major repair--the Glycol is very toxic---like antifreeze but much more concentrated---unless you have done it before I would not suggest it as a do it yourself job.

4.) The bacteria never affects the RED(it does not seem to like that color) and only sometimes the Green.

5.) It may not be worth repairing as most shops charge 200-300 or more for this kind of repair---not to mention that after it is done quite a lot of adjustment to the convergence will be needed from removing and reinstalling the tube.

6.) I know I am not giving you good news but you actually found your problem yourself! If you need any advice or help reply to this post and I will try to assist you.

REGARDS, SD TECH

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

lg70 nice tv excellent processor just to bad there is no intensity control on color management oh well still better than what the three s are pushing block out the hype lg will be number 1 in a few years haters are starting to come around and well leds coming,

p.s. i dont work for lg just tired of losers bashing stuff because they dont own it.
im isf certified those settings are right on the money straighter than a ruler

I suspect if you have green lines .you have a bad crt. there are three tubes red green and blue i suspect blue tube. tubes cost is around 300.00 to fix.


thanks doctor video


note sometimes you could adjust screen voltage located near the front grill black box . becareful high voltage ony a pro should do.

Blue CRT has shorts that causing the set to go into protective shutdown.

sounds like you are using componant cables.[ red,blue,green on the right side in back of the cable box for the picture, & red & white cables for the sound.] make sure the red & white cables are connected to the middle white & red outputs of the cable box to the tv's red & white inputs, not outputs. hope this helps.
