It sounds like a convergence problem and I will attach a few photos of typical sets with this problem.

Confirm the actual model number and I will if it is this tell you what is involved to either do it yourself or give other options.

    Keep in mind I am in California and here from usually after 3 pm to 8 pm or later Pacific time.

    This is a repair I have done hundreds of times. It entails getting at the two convergence chips and replacing them; yes sometimes there will be a damaged resistor around them but that is no big deal and I can tell you what to look for.

    Consider that if you CAN solder and have some basic skills the repair parts needed in total will cost you under 30 dollars---I use a vendor on EBAY who will have everything needed.

    Hitachi sets are my favorite--I own two older than yours and love them. This is about the only real problem they have and life span on this type of part is 5-8 years average and there is a real reason for this.

    If you think you or someone you know is able to do this fix I will tell you what you will need, step you through the repair, and help you until you are finished. WE can communicate here and sometimes if it is needed (it is not allowed by this site but I have done it to really help someone) we can go to Yahoo IM and chat there.

    I had another person with a similar set and same problem and after ten comments back and forth he gave me his yahoo and we met there. I told him where to get what he needed and when the parts arrived I spent almost a hour online with him as he actually did the repair.

    No money changed hands and my reward was knowing someone in a city 3,000 miles away had fixed his set and was happy and yes grateful.

    This set is worth saving and much less than buying a Plasma or LCD which are much less reliable and have all kinds of troubles. Look at all the people on this site with those kinds of sets with problems.

    Let me know to some extent your skill level and if you think you are able I will assist you.

    With Regards, SD TECH

The picture & contents are outlined in red green ,yellow colors


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

My Hitachi tv no longer has any green contract when I try to change the hue as a result my tv has a large centre area that seems to have a redish hue and no matter how I try I don't get any real color...


Hello,

This problem is very common with rear projection TV's.

It is related to one or more of the colour guns being out of alignment or needing to be replaced. The only way to correct this issue is to have a technician come in and fix it or bring it into a repair center. I personally would suggest purchasing a new TV. The cost of getting them aligned is usually more then a basic LCD.

Hope this helps

53 inch projection tv...seems like the color red and color blue have shifted giving me a picture with red and blue shadows


For CRT projection TV's, this indicates that the Green picture tube is burned (warn out). The less green that strikes the screen, the more redish the image will look. You will need to find an old school TV repair shop that knows how to replace picture tubes.
In the case of a DLP style TV, the color wheel needs replacing.

Blue off to right outlines everything


The convergence amplifier IC responsible for blue alignment needs to be replaced. This is not an easy repair. Most reputable tv shops charge between $200 to $300 for this repair.

It sounds like bad solder connections in the convergence output circuit. It may also be an intermittant convergence output ic which will need to be replaced.
