My hitachi tvs blue doesnt line up with other colors ive turned off the blue but need a better solution?

the blue is about an inch away from the other colors. it is very defined not blury or distorted just not lined up causing a blue shadow above everything. If there are word on my screen in a normal color there will be the exact same words just above in just blue. iv cleaned the lense and even tried changing with the red (not the bulb just the lens) still no change. ive adjusted the colors on the front of the tv(behind the front face) and have now turned off the blue so the kids can still watch tv but is a little difficult to watch Blues clues without the color Blue....PLEASE helpMy hitachi tvs blue doesnt line up with other colors ive turned off the blue but need a better solution?Sounds like your convergence amps have retired ! Wait for the other Techs to come on and maybe confirm my diagnosis , my speciality is CRT TV and the PAL colour system .

Cheers Pete

Pete's right....I'd be looking at the Blue Convergence amp being dead and possibly some resistor being smoked.....



That's a normal failure on Hitachi....



But what worrys me is the FACT you got into your TV set...



Because now I have to wonder if that was your ORIGINAL problem to begin with....



IF NOT....then you probably rotated the CENTERING MAGNETS on the Blue CRT, and you need to get back in there and realign them using the glue marks to reposition them to the manufacturer's original position.

They should never be changed, unless you replaced the blue CRT......



Now, to see if your CONVERGENCE amps are bad....go into the Flash Focus or the Auto Focus %26lt;%26lt;OR%26gt;%26gt; the manual convergence and see if the BLUE MOVES UP/DOWN and LEFT/RIGHT......



If it doesn't....then the amps need replaced, along with the resistors.....THEN you can align it with the Auto Focus or the Manual Convergence....
