Question about Daewoo F227B Monitor

1 Answer

I'm trying to service a Daewoo Monitor f227b

I need help in opening up a Daewoo Monitor model f227b. I've removed the 6 screws holding the tilt brackets on the back. There are no other screws to undo. In the lower right hand corner of the back there is a small horizontal slot with a picture of a padlock with a 'K' inside. Is there a special tool needed to unlock the front from the back ? I'm trying to check to see if there is a blown fuse in the power supply. There is no indication of power on the front panel.

    Well, I have the same prob....Got the case off, now how do I get the screen out?



1 Answer

The slot with the K on it is a Kensington lock, it is an anti theft lock and does not affect the disassembly. Most monitors can be carefully prised apart as they are only clipped together.

My 6 year old Daewoo F227B began to fade yesterday and go a bit blurry. Is there a fix for this or do I need a new monitor. My computer is about the same age.

The back lighting which is made up of a fluorescent light array, dies, as you have experienced. The picture in most cases can still be seen but it is very faint. Yes it can be repaired.

Phone around to get an idea of cost, you will have to decide which option sounds good to you. With regards to the cost of repairing or the cost to purchase a whole new monitor that is bigger and has a warranty.

You may find that a new monitor is relatively cheaper, remember that the monitor is not to be thrown in the bin.

Take care!

I am not getting anysound from the speakers

This monitor has integrated speakers so therefor needs an audio cable to plug in from your computers Audio Output Socket (usually green color) into the monitors audio input jack. It needs a stero type plug for right and left sound. Have a great day.

Vertical n horizontal ic

Are you asking about this LCD Daewoo (F227B) monitor? LCD monitors do not use Vertical/Horizontal IC like the CRT type for the H/V Yoke.
What is the problem with the monitor?
Common problem with LCD monitor:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Replacing ignition switch on 1976 Dodge D-300. Got the steering wheel off and taken out the circlip holding in the bearing. I''ve loosened the three screws that hold the turn signal housing, but can''t...

Here is what MOTOR says to do. If you have Tilt and/or Telescopic steering wheel the column needs to come off the dash and the mounting bracket removed so the cover on the wire harness can be removed. It is mounted with screws. On the others the wire cover is held on with clips and need to come off. The shift lever has to be full clockwise on all models except Tilt. On Tilt wheels position the gear shift at the midway point. Unplug the wire harness and remove the screw for the turn signal lever and then the lever. If you have cruise, let it hang. Remove the hazard warning switch and upper bearing retainer mounting screws. Pull the switch from the column carefully, guiding the wires through the column opening. Installation is the reverse.Hope this helps.

No power in my Daewoo Monitor

Hi, Youo have zeroed in on the problem area. It looks like a power supply problem. More often than not, there is a fuse inside. If you would venture to open the unit up, do a visual check on the fuse. If it is busted: 1. Clean - no burnt/scorching/black marks inside the glass tube, then you can simply replace and hopefully the unit will be operational; 2. Dark smudges - or small burnt metal pellets inside the glass tube, then it is possible that you have other defective components that caused the fuse to blow. Normal components that are known to go bad are the big capacitor and or the power transistor regulator. Most current designs uses a switch mode power supply where your mains AC voltage is converted to DC that powers a circuit that eventually produces a lower DC voltage say 12VDC for use of the monitor. Should you venture a DIY (do-it-yourself), pls remember safety precautions when working with powered electronics. Hope this be of some help/idea. Post back how things are or should you need further information. Good luck and kind regards.
