SOURCE: green picture and distorted

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

SOURCE: 50" hitachi 10 years old has blue and green colors

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

My hitachi 53udx10b was supposedly just serviced but the picture is extremely blue. Have tried adjusting picture to no avail. Help.


I am going to tell you a simple thing to do to know what your problem may be.

With the set on turn the color all the way to zero. Go to a channel if you can that is in black and white. What color is the screen?

If the answer is that it is blue in the background whoever serviced the set did not and could have removed front speaker grill and inspection plate behind it; there is a black plastic block with three screen controls (red,green,blue) and 3 focus controls (do not touch the focus ones.)

I suspect if the blue screen is there a slight adjustment of the blue screen down will correct this.

The picture with the color at zero should be black and white or gray. If blue is background color it will also be with color.

This is called gray scale; picture with color off has to be gray or black and white.

Before you rate this solution if you have questions make a comment right here and I will advise you.

Over time a thin layer of fungi grows over the top of your BLUE CRT preventing light fronm shining through. This causes you to loose the blue color in your set. Check and clean. Also when the back is off your set check to see if your blue CRT is on. If not you may need to replace it.

OUR HITACHI 50V500A HAS COLOR PROBLEMS WE MOVED IT


This is an LCD rear screen projection TV. There is a Red, Green and Blue LCD pallet that is mounted on what they call an X-cube. If all you are getting is Red and green then something happened to the blue pallet. Either the Ribbon connector came off or is loose or something worse. How hard did you mover it?
Another thought. How is it hooked up. If component then this may be the issue as component video connections are Red, Green and Blue. Just a thought.
Let me know.
Blessings always,

Sounds like Calibration is needed on the projection internals. Your TV uses a rear-projection system and the problem is either in the imaging LCD Unit or the light filter. I see in a previous thread you have changed the bulb. You can invest in a voltage regulator to keep the hardware in factory condition.
Also you can burn a DVD of a stuck pixel remedy video and run it on the screen with full brightness and full contrast. This is used for plasma burns and stuck pixels on conventional Flat panel TVs but can repair color issues with projection systems. This therapy is focused on the imaging unit between the projector and the main drop of your tv.
please feel free to post a more in-depth description or any changes

Hitachi has had problems with their light engines. Very expensive. Contact Hitachi as they may give you consideration even if this is out of warranty.

Hitachi 51F710 Lack of green in picture


that is a color channel that is broken...

You need to increase the red or decrease the other colors. this is done with small preset controls on the neck board (or inside in the back of the CRT)

if that doesn't help. you might need to send it to a repairman before you get electrocuted (it doesn't matter if its unplugged or not, the crt stores lots of electricity)

How to change lamp on Hitach 60vg825


Yes, you are due for a lamp. Save yourself some money by ordering just the bulb p/n UX21516 (instead of the whole lamp assy), install it yourself. There are lots of us that sell these bulbs far below what the assy costs. Make sure it is an OSRAM bulb though.

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.
