Question about Hitachi 50GX30B 50". Rear Projection Television

2 Answers

Color Allignment The blue in the television is completely misaligned.  When I go into the digital array I am able to fix the red, but am unable to move the blue at all.  I think that my blue bulb is broken, but it still projects onto the TV and works fine other than the fact that it doesn't want to be aligned.  Is there any way to correct the colors by hand?

Auto convergence yields with unable to complete due to unresponsive sensor


Your convegence has gone out. You can get complete kits with instructions from sites such as www.TvRepairKits.com or just the parts from www.ConvergenceChips.com . If you have never done this before i would suggest going the kit route since it includes step by step photo instructions and support.

Projection TV red is drooping


Do an internet search on "Hitachi Convergence Circuit". This apparently happens all the time. TV repairmen charge about $400. Parts are less than $50 but you would have to be an expert at soldering electronics circuits to replace it yourself.

My TV had the Blue misalign instead of the Red. I ordered the kit #9 from http://www.bdent.com/search/part.jsp?partnum=KIT9

DO NOT ATTEMPT IF YOU DO NOT KNOW HOW TO SOLDER. YOU WILL PROBABLY RUIN YOUR TV.

Dominant blue


Can you post to the party who has too much green how to adjust the video adjustments? They need to know so they can see if
its just a simple adjustment.
In your case, first turn the color level clear down to where you
have a black and white picture. As in the case of too much green,
question is if the picture is black and white or if there is a color
on the screen so its blue and white? I suspect it will be which
is typical when the guns start to fail. Likely the green and red
guns are weak in output. There are screen adjustments in the set that a tech can set up that may help some, but the only real fix is to replace the guns which is expensive and requires a complete allignment. All 3 guns need changing to get it back to spec and it is a good idea to replace the flyback for reliability. Get an estimate and likely you can replace the set for the same money.

Red color allignment


The convergence Ics need replaced. In Toshiba, resistors and sometimes a coil needs replaced as well. The convergence/deflection PCB is available, but, the cost of that board is higher than having a servicer come to your home and repair the unit to component level. If you are not familar with this circuit, then call a servicer. Have them replace both ICs not just one. Make sure they are repairing to component level and not replacing the board. Hope this helps.
