Question about Hitachi 51S500 51" Rear Projection HDTV-Ready Television

2 Answers

Hitachi 51S500 51 in.

My Hitachi 51S500 51 in. is sick. Everything is fine except the colors. What should be red is green and what sould be green is brown. Blue and yellow are fine. I thought it was the red lamp but when I use the setup tools the red screen shows brightly. What do I do next?

    Thanks for the response. Is this a repair that I can do? If so, where can I purchase the replacement lamp?

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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. Solution #1

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

Yellow haze


The blue filter is burnt out. A very common problem in Zenith DLPs. There are 3 color filters, 1 blue (a pinkish color), 1 green (a grayish brown) and 1 red (it is red) they give you your colors for you picture. This is a simple fix.

Pictue is dark as hell


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

Picture is yellow and green


Your missing the red drive on the set. Its most likly the picture tube. Its a possibility that the red drive circuit could be not working so the best thing to do is take off the gree picture tube socket and put the green board on the red tube. Of course do all this when the set is unplugged. if you have no tv experience. its not a good idea to be messing around inside of these sets.
