To adjust the focus control(s), some monitors have a set of focus controls, some are on the pcb, some are on the circuit board and some have both.(gosub warning message)

 

while KEEPING ONE HAND IN YOUR POCKET use an INSULATED SCREWDRIVER to adjust the focus controls if there are 2, do one then the other and go back and forth until the correct focus is obtained, if you can not see the screen easily work from directly behind the monitor and place a mirror in front so you can see the monitor from there.

 

after getting the focus correct use a small drop of nail polish between its adjustment shaft and the housing to lock it in place.

 

warning message:

THE HAND IN YOUR POCKET IS TO KEEP YOU FROM GETTING A SHOCK THAT COULD GO ACROSS YOUR CHEST AND DO DAMMAGE TO YOUR HEART!!!!!! THERE IS A LOT OF VOLTAGE ON THE ANODE CAP OF THE PICTURE TUBE, AS WELL AS A FEW OTHER PLACES IN ANYTHING WITH A CRT.

Focus controls are on the back of the flyback transformer. You may have bumped one while the back was off. Due to dangers working on live circuits I recommend you have a service professional adjust the focus.

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.

Diaplay Letters not cleard

Open your monitor's back cover and on the circuit laid underneath the CRT you will find a big black object. Check it, there will be two knobs having H- focus and V- focus, control them and your CRT will focus correctly. If still problem persists on the CRT there is a white box with three control knobs, adjust them.

SYNCMASTER 753S

I would say your monitor is toast. However, you could test this theory by hooking up another monitor to it and see if it does the same thing.
