Question about Sony VPL PX40 Multimedia Projector

1 Answer

Two problems, first the menu appears to be burned into the projection, the bulb has less than 100 hours. Second when black is supposed to be projected it projects blue?

The menu appears to be "burned" into the projected image.

Why would the color black be replaced with the color blue, is some setting off or what would cause this?

You have a bad lcd, you would probabaly have some blue lite leakage also. Any lcd projector should not be left on the same image for long periods, it wears out the pixels that control the lite thru. The blue lcd is usually the culprit.

Poor viewing quality


By poor color quality, do you mean that if you turn the color control all the way down, the black and white picture is more like black and red, green or blue - or do you have a good black and white image? If the B&W image is good, and the TV is an old (8+ years) one, maybe the mirror inside the set needs a good cleaning - especially if there are smokers in the room. If you have a B&W picture that is tinted, then you may have to go into a service menu to adjust it back to a better picture. Hard to guess the problem without more specific description of symptoms.

Sony model #kp51ws500. Common problems for screen appearing warped


Need more details about how the screen is appearing warped.

if you have color separation and distorted image (warped,bowed, etc), then your Convergence ICs have failed. It is very common on rear projections. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.


Note if one STK chip fails, you replace both regardless.


Note: The STK chips are black about 3 inches long and will be mounted against a large aluminum heat sink (metal fins). They have about 20 pins on them. I believe they are STK392-560s in that set.

The picture is producing a double image which appears to be in red only with a slight bending of the images on some parts of the screen.

The tv image is showing in three colors....Almost ghost like but in three colors. I checked my connections and tried my blue ray player and the image is still messed up....I did press the magic focus...


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

How can i fix the brightnees in my 61md10


there is a menu setting for best pix or longer lamp life.
Also, turn up brightness of picture settings(different menu)
Also use daylight setting, vibrant, (different menu).
Bulbs dim over time and dust can accumulate on projector lens, mirrors and (not so much on mine) back of screen.
New lamps tend to melt a plastic lens in light engine, a dark shadow may start to appear upper left or center. this started to happen to me with new bulb, (Ebay O.E.M. supposedly $114). I switched back to original lamp hopefully to slow the burn till I can tacklle a repair. Take a look at this website. Hope that helps.
