SOURCE: PROJECTION TV HITACHI ULTRAVISION COLOR CONVERGENCE PROBLEM

it sounds like your blue convergence ic is getting weak you need to replace the ic's STK392-110 and you should replace both because when 1 is bad the other will go real soon. They are inexspensive at the sight I posted and you will also get free tech online support if you purchase them there.

SOURCE: hitachi tv magic focus does not work

Your problem is the convergence circuit. This is very common in CRT projection sets like yours. There are a couple of IC's that need to be changed and possibly some resistors. A good repair shop will run you $400-$500 to do the repair.

Replace Both of your STK ICs they are your convergence ics they are big black ICs will have Part# on them for example STK392-110, if they are 110s use 180s, if 020s use 040s other wise replace with exact same number. To get Parts call Electronix 1-800-223-3205

My hitachi 60"ultravision tv has a double image at the top in blue and yellow. the magic focus has no impact. any ideas?


Pretty common failure with rear projection CRT sets.
Sounds like one of your convergence amp chips have gone out.
You can buy the chips from several vendors, or kits.
Do a search with your model number and "convergence amp chips". Shop around for the chips as they seem to be getting cheaper as this type of TV isn't as popular as they once were.
I've picked up several used Sony and Mitsubishi sets for nearly free that had this problem..

Hitachi 51S700 won't turn off


Some kind of a problem likely in the magic focus area--is the set showing a error on screen if you engage the magic focus?

One thing not to do is disconnect the sensors inside the screen as that could make things worse......

Hitachi projection tv 53SDX01B is out of focus how do you reset.


if magic focus will not correct convergence problem look in the customer menu for the word CONVERGENCE---IF BLUE WILL NOT ADJUST IN some direction, one of the two Stk-392-110(or 392-150) convergence Ic chips are bad; you may also find some burnt or discolored resistors behind them----this kind of problem is usually fixable right in your home; if you need direct help;;;
