Question about Televison & Video
I read that there is a blue reset button for the Magic Focus button inside the front of the TV and that all you need to do is pop off the front grid but, I can't figure out how to pop off the front grid on the TV.
The blue button is not for magic focus on this model----the front grill beneath the screen can be removed and behind it is an inspection plate---the tiny blue button is at the front and to the left and with set on and it pressed the set will enter the decam mode----a grid of lines will show and then buttons on the original remote do different things to adjust convergence and then save the adjustments.
I convergence is way off don't try to adjust it as it will only make matters worse---usually the two chips need to be replaced and sometimes a resistor as well.

SOURCE: 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.

Replace Both of your STK ICs they are Big Black ICs Also CK and replace these resistors RK42 3.3 /RK46 1.8 /RK50 2.7/ RK54 1.5 RK54 1.5/ RK58 3.9 /RK62 2.2

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.
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.

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;;;
If this was helpful I would appreciate a vote from you here.

There are two common problems with these sets.
Problem #1) Convergence
