If the width is shrinking, check also if the edges are now distorted too.
If so, there is a 'bipolar' capacitor in the high voltage section that is failing.
To find and verify this, you will need a meter that can measure capacitance, and perferably, DF or losses of capacitors as well.

If you ignore this, the horizontal will continue to shrink until the deflection stops completely and can cause other, more costly parts to fail although these may also be weakened and failing.

I'm afraid this is not a DIY problem.

Where is usb port on model 786n mag innovision desktop


The MAG Innovision 786N is a CRT monitor. It will not have a USB port. Look on the computer for a flat input, approximately 1/2 inch wide x 1/8 inch tall. There are likely two or more together, those are your USB ports. Unless your computer is more than 10 years old...

Well, if the adjustment buttons don't work, then probably the control unit in the monitor is broken, or a key is stuck. If the control unit needs servicing, I doubt if it's feasible to have it repaired, given the fact that it's an old monitor and new or used nice slim LCD monitors can be purchased cheaply nowadays.

I am not able to expand the screen


Did you try to adjust with front pannel switch?

If the switch not working then change the micro switches.

Check the width boost capacitor (Polyster cap. 1.5Kv / 1.8kv / 2kv etc) in Horz. section

Check the SMPS voltage for Horz.

Emachine 786n mointor frozen emachine logo


Try a different monitor. Most likely your having operating system issues that cause the monitor to do this.
Also - try this - As you turn the machine on tap the DELETE key - this will take you to the DOS platform of the computer. If the screen changes to anything you have operating system issues. Try a repair with the original disk or the operating system disk that was last installed.

have a look at the manual.
