Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

Red is off to the right while blue and green light are in sync

Image looks OK without red since the red appears off to the right of the image. If you look at any channels logo, blue and green are in sync but red is off to the right.
I see the the light focus is adjustable with some nuts on each light but does not seem to be the problem. Seems something is wrong with red light for it to be out of adjustment. Any ideas?
Does TV have any adjustment on control to line up the image? Thanks!

    Have similar problem with blue being off vertically on the outer 1/3 on each side - it "droops" down from the other colors. Would like to know if this is worth trying to repair. It went away for a few days and then came back to stay. The automatic convergence focus does not correct the problem

Convergence alignment issues are common to all rear projection
TV's....Repair requires replacement of STK IC's on large heatsink.
After repair, alignment often returns to normal......T.

1) The set of input (Yellow= Composite video, Red= Right channel audio, White= Left channel audio). This set of input is for composite video.

2) The set of input (Red= Red video signal, Green= Green video signal + sync, Blue= Blue signal, Red= Right channel audio, White = Left channel audio (the Red and White will be grouped close together). This set of input is used for Component video for HD signal.

You should try using composite video source (Yellow RCA jack) from DVD player and feed to the monitor and see if it works OK with all color showing that way we acn find out if it is the video source problem or the monitor video signal processing problem. Try the PS2 on the TV if it works OK also.

Picture is red


If you are running component video, make sure the blue is plugged in and in the right spot. Component video works like this: the green is a black and white image, the red and blue are cover overlays to make the image display properly. So if everything looks plugged in right, then try plugging in a composite video (Yellow) or S-video cable switching to the appropriate input, and see if the image is still red. If so, go to the set up and set the set to factory defaults, and see if that fixes the color issue, It's possible that the color settings on the TV are messed up, with the S-video plugged in go through the set up menu and see if you can correct the color issue IF THE IMAGE IS STILL RED WITH THE S-VIDEO OR COMPOSITE VIDEO, otherwise the issue is a problem with the component video cable.

The Fuji S2 sensor is noted for this red sensitivity. Here's a few different approaches to getting the shot with the S2, all of which require some experimentation.

1. Set the "Color" and "Tone" Function options to "ORG". Underexpose the shot. Progressively change the exposure compensation downward until when checking the histogram, the red channel does not show saturation at the high end. Advantages: this is the simplest approach to getting the picture. Disadvantages: the S2 already had a fairly limited dynamic range, and this will make things worse for the parts of the photo that are not red. For the surgical setting and use of a ringflash, this may not be much of a disadvantage, since a lot of the stuff of interest will be red, and ringflash illumination generally is of lower contrast than directional lighting.

2. Set the "Color" and "Tone" Function options to "ORG". Use a custom white balance. The idea here is to have the camera adjust the red channel sensitivity itself, and leave the blue and green channels alone. To do this, start with several sheets of white paper and a red or pink marker or highlighter. Scribble with the marker across a sheet, then use that to set a custom white balance. Take a test shot of the red stuff that has been problematic, and see whether the histogram for the red channel shows that there is no saturation at the high end. Repeat this with progressively more red or pink on each sheet used to set the custom white balance until you find the custom white balance that takes enough of the edge off the red channel response. Alternative: I just tried out making a gradient across an 8.5x11" sheet of paper going from white to about 30% red saturation. I can set more or less red adjustment in a custom white balance just by pointing the camera at different parts of the page. This seems to work OK for me. Advantage: can allow the full dynamic range of the sensor to be used. Disadvantages: the experimentation period is likely to take a while to get the best results, and the final images are unlikely to look completely natural.

3. Set the "Color" Function option to "B/W". Use a green or cyan filter on the lens to cut the amount that the red color channel contributes to the final image. Advantages: this is fairly simple as an approach. A similar post-processing technique can be applied to the photos that you already have, by nulling out the red channel contribution and desaturating the blue and green channels to produce a grayscale image. Disadvantages: you lose the color information entirely. Since much of what you want information about is colored red anyway, the organs are likely to appear quite dark when only taking the blue and green channel contributions to the image.

Did you use the Automatica Convergence to try and straighten it out? If that does not help, you can manually adjust the convergence.

YOu have convergence issues. Ok first question. IN your setup menu do you have the convergence option/ if you DO not then it can be a specail fusable link. fl231 if you do. next question do the picture bow in at the middle. if you do then it possibly a convergence power supply issue. next if you go into setup convergence does the crosshairs adjust up or down left to right on both blue and red. I if so then theres is a chance that it can be a convergence adjusment or a amplifer problem AS always THIS SET CAN GENERATE LEATHAL 380 VOLTS EVEN WITH SET UPLUGED SO BE CAREFULL.
