This must be adjusted by a professional television repair center

Or if you are me you can open it up and start looking for the internal focus adjustment block
normaly located on the flyback transformer

I highly recommend you don't go digging around in there unless you know what you're doing.

I'm not responsible for accidental death due to following my trouble shooting procedures.

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..

Convergence


I presume it is Hitachi---if Magic Focus does not correct the problem--the convergence chips need to be replaced.

Based on a MODEL NUMBER several sites on the internet sell kits etc.

I am available to help if you provide me with a model number and some idea of your skill level.

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;;;

Yellow and blue color ruins total picture on 50" tv,can't get rid


lupe0112,

I'm no expert, but I think that you have a problem with the convergence of the 3 color guns. I've been working on a similar problem. As a first step, have you tried "Magic Focus?" The Magic Focus button for the Hitachi 53UDX10B is at the left of the small front panel controls that also include your RCA composite and SVideo connectors. Let the set warm up for about 20 minutes (as recommended by the user guide), and then press the Magic Focus button. When you press the Magic focus button, the set will auto align the 3 color guns. If this doesn't fix your problem, unplug the TV for at least 4 hours and try again.

Magic Focus does not work.


Convergence issues usually resolved by changing convergence output amplifier IC's.....Original STK392-110 should be replaced
with upgrade Stk394-160E Hitachi part # CZ 01341,change both
for reliability.....check B+ feed resistors for over-heating....T.
