SOURCE: bad color

Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

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 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.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

SOURCE: hitachi 51f500a rear projection tv screen looks 3d

This model uses two convergence IC's----if 3 D one or both are bad.


Most of the time this set uses either two of the STK-392-110 OR THE STK-392-150 CHIPS.

Both chips and any bad protection resistors around them need to be replaced and the set adjusted.

If you are able to do the repair yourself total parts cost will be under 30 dollars.

Some history for you:
This set like all rear projection tube type sets uses two chips---the ones in your set are Black in color--about 2 1/2 inches wide X 1 1/2 inches tall and are on either one large or two smaller heat sinks with fins on them.

When the chips are installed a white grease called heat sink compound is applied to the metal back of each---the grease transfers heat from the chip quickly to the metal it is bolted to.

After some years the grease dries out from the heat and one of the chips goes instantly.

You can buy a pair of the chips for your set on Ebay for less than 15 dollars plus shipping--

If you cannot do the repair yourself--shop around your area---most shops charge 300-400 for this type of repair. Whoever you get to do it make sure BOTH chips are replaced or you will have the same problem in a few months.

If you open the set and locate the chips---they will have the full STK number printed on them in white letters----there are about 12 resistors around them that need to be looked at--if any are discolored they need to be replaced.

If a shop says it HAS TO GO TO THE SHOP keep looking as any good tech can do this repair right in your home in about 1 hour---I know as I have done hundreds of them.

IF you can solder and are handy I will give you general instructions on how to do the repair and what you need---some people I talk to can either do it or have a friend who can do it for them---let me know

I can tell you what you will need aside from the parts and how to proceed with the fix---

If all this helped rate this solution---I do this here for free.

IF YOU HAVE ANY QUESTIONS OR NEED ADVICE LET ME KNOW--I am here to help people.

Regards, SD TECH

CONTRAST ADJUSTMENT


it is best to shut the color level to the lowest setting then try t balance the screens to achieve the best black and white picture. then turn up your color level. Your brightness level should also be set to 50 % then when you adjust for the best B&W picture. You will have better color and brightness when you reset your color and brightness levels.

the bulb only makes the brightness needed for the color engine to show through the color engine on your set is on the downward spiral and the bad part is they coast as much as 6-10 bulbs plus you have to get them installed sorry to be the bringer of bad news

Cant adjust the color on the tv


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...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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

Screen hazzy and issue with blue convergence


bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.
