Hitachi Projection Color Lines

We had it fixed by an expert, replaced two STK 4274 Resistors, only cost $300.00, works great now.

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


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...

*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

I just had the convergence replaced and have a great picture

Rear projection t.v.s work differently than most. They have threw lights that throw the picture onto the screen, instead of having a color tube that is in a traditional television. It would be my suggestion to bring it to a Qaulified T.V. professional to have watever bulb is bad replaced. odds are it will either the blue or the green(hard to remember exactly but i think its a green one lol) and not the red.

i think you need a tech .because all the users adjustment were tried.

i have a hitachi projection tv and im getting blue lines behind the lettering and on different spots of the screen can anyone help

The problem is called green geometry.There is nothing wrong w/the green pix tube.It is critical to get the green geometry

accurate because the red and blue convergence overlays on

the green.If you have more than an alignment issue,that will need

repair before adjustments are attempted.

Sounds like your convergence amps need to be replaced (STKs). I am not sure what the rates are in your area, but typically you're looking at around $200 or so.
