Does the magic focus work on your set ?

If it doesn't you must replace the convergence Ic's with a kit that is available through your local parts distributor

You must replace all resistors in the kit
If you are not good at soldering and de- soldering have a local tv shop do it for you

Good luck

We got a free hitachi projection tv that i believe has a bulb malfunction. on the left half of the screen has a red shadow we cant afford a hundred dollars for an estimate then whatever the price of the...


You might need to adjust the red screen drive control, turn the Red down and see if that clears it out. Sounds like the Red Tube is over driving the Green and blue Tube.
Find the Focus and screen control block there will be 3 controls on Top 3 right under them R-G-B they adjust the Focus to each tube and screen drive for each tube. also you need to clean the lenses off top of each tube they get dirty and dusty and it would help to clean the mirror

Green glow on the screen,top center/left


Does this look like it is three d and thecolors don't line up?

If it does then you need to replace the convergence Ic's

Hitachi makes a kit for that tv that would be available through a local parts distributor
If you are not experienced with soldering and component removal then have a local tv shop do it for you
I would not pay over $250.00 to get it done

Good luck

Screen hazzy and issue with blue convergence


bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.

Blue and Green line thru center red shadow on both sides


most likely if the line is top to bottom you have no horizontal deflection
this could be caused by a number of things
but if you continue to turn it on it will score a burn mark on the face of the three crts
id call a service ctr in your area or you might try replaceing the deflection bd and see if this will resolve the problem

the problem could be a open yoke return cap but if you dont have the tools or knowledge this woulld be one better left to sme one more experianced with this



please let me know il be happy to try and assist you further

Red & green lines


Sounds like you have hardware failure in the convergence circuit. Some combination of the IC's, fuses, and/or resistors has failed. Repair cost is $250-$400 parts & labor
