Most of the time, the focus pots are H and V access. Use any software or
text that can produce a fine image to allow for focus adjustments. I use
white text on a black background, with the computer running at the optimum
resolution for the type of monitor. Use what is best for you to visually see
what you are doing.
In some monitors the focus adjustment will effect the convergence. If you
want to achieve the optimum, you may have to also get in to the convergence
setup if this is the case for your particular monitor.
The main cause for the focus to drift out is the CRT going weak, and or the
HV module is starting to go out of specs. With age, these parts tend to
eventually fail. Usually they fail slowly.

Hi ,
Can someone enlighten me as to why there are two focus pots on the FBT
in these 19'' monitors , all i know is one is called "static" and the other
"dynamic"
Also whats the best procedure for adjusting it , i have a program called
Keonig but
i seem to get better results with a text document with a white background .
Is there any other software freely available for testing monitors
thank you

There's usually two controls on the flyback that adjust the focus.
One will mostly affect the vertical focus (adjust for sharpest
horizontal lines) and the other mostly affects the horizontal focus
(adjust for sharpest vertical lines). The controls interact, so
you'll have to adjust them both several times. Be sure to wait for it
to warm up for about 20 min before you start.
I like to adjust the horizontal focus for the sharpest vertical lines
near the left and right edges of the screen, followed by the vertical
focus for the sharpest horizontal lines in the middle of the screen.
The horizontal focus tends to affect the edges much more than the
center. You mat have to compromise between center focus and edge
focus to avoid the corners being way out of focus.

I have just completed a full bridge converter design and am about to
make all files public. Artworks, simulation files, design notes, etc.
Can you tell me a little bit more about your application? I might be
able to help you out.

SMPS are DIFFICULT! Except for the gurus who have designed hundreds.
It's much better to start with a transformer/rectifier/regulator
'linear' supply, but then I always say that.

Oh, it does, but the OP doesn't yet understand the reservoir capacitor.Not wishing to be tiresome or contentious either, :>
rectified AC into DC" also involves the various additional items you
need to deal with the ac lines: switches, fuses, common-mode filters

What size would a full-bridge converter for 13kW be?
Would you happen to know of a website with information on that? Or is there
a fundamental measurement for a per-watt approximation? I have just been
doing calculations from formulas I get out of these books I bought. I'm
going through and studying and this full-bridge rectifier looks like it
could be an interesting POWERFUL project! What are typical ratios for the
transformers? Where do I get these high power transformers? Can I get ones
that operate much higher than 50-60hz?

I have my A.S. degree in electronics. I have experience with
microcontrollers, and I don't need to build a linear regulator because I
have repaired them before. I'm just in experienced in the area of SMPS which
is why I am so enthusiastic about it. They seem to be really neat. I'm
paticularly interested in reading some notes on making a buck regulator to
REPLACE a step-down transformer/filter/linear regulator supply, like what
regulator/controller to use for what application. I was thinking about
making a simple buck regulator to plug into an AC outlet and use it to power
a PIC, I even designed the coil and filters in spice simulation software for
those power requirements. I just need to find a controller or regulator to
use. I have bought EDN power supply design, and switching power supply
design. They gave me a good understanding of how they work, but I'm just
empty on projects. Yes I am unexperienced at designing SMPS. But anyone with
a fundamental AC and DC theory education can understand this paticular
application, and I do because I have taken the time to start reading about
SMPS.
