There is a focus adjustment inside on a part called the flyback transformer. It's located toward the back of the circuit board, and you'll know which part it is by the red cable going from it to a connection on the picture tube. The flyback generally has two small adjustment knobs on it. The focus knob is the upper one. Slightly turning this one way or the other may improve the focus a bit, but usually a sudden loss of focus means either the flyback or the picture tube has failed. Either of these is cause to treat yourself to a new monitor. You can buy 17-inch flat screens now for less than $150 at regular prices, and sometimes you'll catch a good sale at the office stores.

If you choose to try the focus adjustment, BE VERY CAREFUL!!

1) You have to remove the back of the monitor and work with the power on. Parts inside, especially the picture tube, can give you a very nasty shock AND EVEN KILL YOU.

2) Be very careful where you are putting your fingers when working on a live set. Make sure you have a safe grip on the adjustment knob first, THEN look at the screen while you adjust it. Don't go blindly reaching around.

blurr y means focus out.
Also adjust brightness (reduce and check half an hour if not blur quickly need to adjust focus)

therefore need to getting help by professional technician to adjust the focus preset in the Fly back.

Also need to careful to avoid arc high tension voltage from anode and from fly back.

Also don't turn white balance much . may be monitor display off when power on if turned more. if reduce much monitor will black.

CRT monitor screen is out of focus.text and other images looks blurry


Hi,

This kind of symptoms can be correct by the focus adjustment at the flyback transformer. FBT mostly has two control knob (Focus and Screen), focus is usually at the top one like in the sample picture below.

Open the back cover of your unit and then locate the FBT. Power on the unit and try to adjust the focus knob.

If the symptoms can't be cured by the this step, this is an indication that the CRT socket is already faulty. You have to replaced this parts and then make some adjustment at the focus knob of the FBT and your unit will back to normal again.

My monitor is blurry and everytime i turn it off for 20 - 30 mins it comes back, but for only a short time then it gets blurry again, my monitor is ft 500. can't see the focus hole.


I would follow these steps in order. Stop if one solves the problem.

Are you using any cable extenders or after market video cables? If so
try without them or with a different cable. If not go to next step.

Try removing and reseating the video cable (turn the computer and
monitor off first).

Try resetting the monitor to it's default state (you'd have to read
the manual for that)

Try removing and re-seating the video card (turn the computer off to
try that)

Try running the monitor at a different resolution (and/or a different
refresh rate.)

Try updating your video card drivers.

Try a different video card

Try a different monitor.

Focus is way off...screen is blurry????


is the monitor a flat screen? if so, you can try the autoadjust button, which is found by pressing the monitor menu button, and cycling through.
