Question about Samsung SyncMaster 930BF 19" LCD Monitor

1 Answer

Screen on first start doesn't work

I've had my PC and syncmaster for about a year now and ever since i first had it when I turn my PC on for the first time the screen wont fire up and it flashes analog/digital in the top corner and then the green on light flashes. I then have to wait until my PC is finished booting before turning it off at the switch, turn it back on and then generally the monitor fires up second time. This is not helping my PC much as i am not shutting it down properly each time i have to do this...... can you help??

Hi there,

I have a SyncMaster 931BW which I duel Screen with a analogue montior.

There are Three things that I would check:

  1. Connection: if you are using the DVI adaptor, try using just the analogue (VGA) connection into your PC. You may have a faulty DVI adaptor which the PC cannot detect an output device.
  2. Drivers: If you have a standard monitor connect that to the PC and see if there is any output, if so, you may need to install the drivers for your monitor. You should have a Samsung Drivers Disc, or visit the Samsung website:
  3. Cable: ensure that the cables are not knotted, and that within the adaptors the pins are all there and not bent as there is not a proper connection with the device.

Try them.

Check signal cables means there's no signal on input. If your PC still shows up on a different monitor then it's a time to replace a mainboard in your monitor.

Syncmaster 913v not optimum mode

I just resolved this problem for my SyncMaster 913N.
It seems to be a known issue, however it can take quite some time for the problem to occur. In my case about 3,5 years, so well out of warranty.

Short term solution: unplug your monitor from power. The switch on the front is not good enough. Pull the plug and leave it for an hour or so (all night if you can). Good chance the monitor will work next time you power it up.
The problem will is likely to come back..

Permant fix requires some basic soldering as per this video:

I just managed it and it has been ages since I soldered a resistor so you may very well be able to do it. I spent $25 on tool and part and saved me from buying a new monitor.

Problem with syncmaster 204bw

Hi there.
unfortunately this is not a driver issue. if possible, test this screen on a different PC/Laptop.
it sounds like a problem with the screen itself - meaning you will have to take it to a service centre, or if its under warrantee - take it to the shop you baught it from.
*** NB note: samsun screens normally carry a guarantee of AT LEAST 3 years, and not only 1 Year.

Monitor not working

The inverter board has probably failed. Mine turned out to be the clamping diodes on the inverter. It would act like it was firing up but shut down just as the screen would normally come up. I replaced the diodes and it fired right up and has been working great since.
