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!

You can see the red blue and green lines on my tv it is like it is out of sync

I'm not sure what you mean by the "lines". If you mean the image looks like "double" (or triple!) vision, then you need to adjust the red/green/blue convergence. This is especially noticeable with white images on dark background (like text of credits). If this is it, check you manual or explore your menu via the remote. Sometimes convergence can be a problem if the tv was moved or experienced large changes in temperature... or sometimes all by itself!

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.

Double Image Red and Green

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.


You need to replace the convergence chips and convergence resistors. Check the site They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

Red,Blue,Green Image

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.
