Magic focus on a Hitachi only adjusts at 16 points on the screen and needs to be done in a dimly lit room. Frankly its a sales gimmick, the number 5 means one of the sensors inside the screen for the Magic focus is not connected or bad.
Go into the tech mode for convergence with the original remote (that menu is called the Decam mode) and see if convergence will adjust there. There are close to 120 points that can be adjusted there as opposed to less than twenty in the magic focus mode.
If Magic focus will not correct it (it is the limited auto convergence for this set) both the convergence chips which should be stk392-110 or 150 will have to be replaced, convergence is done with the original remote with set in the Decam ( tech convergence mode).
The parts are not that expensive and TVrpairparts.com sells kits with instructions for these sets by model number.
Please! Stop using the magic focus now! There are internal parts that have failed and this requires attention by qualified personnel. The more you hit the magic focus, the more the proper calibration points will go off the mark, since the computer only knows that the calibration is incorrect, but is unaware that the parts that DO the calibrating are defective. Sometimes this will make the repair more difficult, since a major maual recalibration may be necessary if the registers "rolled over". If no one had touched the magic focus and just called for repair, the set would just need the parts. Once replaced, the set would look normal. Yours will require a few more steps.
The correct model is 53fdx01b. There is a mogic focus button on the front of the set.
Procedure for Chassis DP05F, DP05, HP11, HP12:
1. Press and hold the DIGITAL ARRAY or CONVERGENCE ADJUST button on front panel.
2. While the button is held down, then press the INPUT or ANT button on remote control.
3. The unit will now be in the DCAM.
NOTE:
1. Proceed with digital convergence adjustment.
2. Remember to save the correction data.
3. Units with MAGIC FOCUS only - Failure to initialize MAGIC FOCUS sensors after saving
convergence correction data will result in a STATIC (+) display when MAGIC FOCUS attempts
to run. The technician will then be required to access the service only switch behind the front
cover to get back into the DCAM to initialize the sensors, since the procedure to access DCAM
without removing the front panel, requires MAGIC FOCUS to be running.
4. To exit, press the POWER button on the front panel.
You need to replace the convergence chips and possibly some of the convergence resistors. You can buy the parts online from various sources or you can get a complete kit with instructions from www.TvRepairKits.com
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.
That's a DP23 chassis, why replace the deflection board? Does magic focus come on the screen? Does it just no converge the picture? If so, it's likely that the convergence amps have failed.
That unit takes two STK392-110 Sanyo built Ics at board position Ic04 & Ic05. If you replace them I'd upgrade to the STK392-150's for greater reliability.
