Question about Samsung SyncMaster 931B 19" LCD Monitor

3 Answers

Blue power LED flickers on and off; monitor won't turn on

This happens periodically when we reboot the system. The display flickers on for a split second then goes black and the power LED begins flashing. Usually, the problem is fixed if you turn it on and off several times but this time, it isn't working. What had the same problem with an LCD from another manufacturer (Gateway) and it never did come back on. We need to know ASAP because we rely on our computers for our home business. We've ruled out problems with the video card and operating system (Windows 2000 Advanced Server), so it has to be the monitor.

    I have the same problem.. When you power on the unit the power light just flickers and the monitor stays black. I tried a different power cord, reboot etc. I also have a Samsung 931B. Manufactured in April 2006.



    Any suggestions? Is it still covered under any warranty? the serial number is ME19H9NL4166455 R



    THANKS

    I have the same problem with black screen and flickering light. Nothing works. I guess they are just crappy monitors.

Yup, my monitor had similar symptoms. Replaced 3 bulging caps on the power board and now it is perfect.

I have had the same problem with two of these monitors. If it is not still covered under warranty, start by opening the case. Once you remove the power board, you will probably notice several capacitors (the round, can shaped parts) that have tops that are not flat. If you see any that have bubbled tops instead of being completely flat, they need replaced. Once they are replaced, the monitor should turn right back on. Hope this helps.

HP Pavilion F1503 only displays a split second?


well, its a 2003 LDC 13 years old ,
its bad
the monitor itself of the power pack to it is bad.
you can test it on any PC< or laptop made
if its dead on all , then its dead.
what more needs saying,
older LCD monitors had old CCFL, lamps. that love to fail
newer are LED back lights that last for ever. it seems
so up grade?
seems your back light is dead
ever do the flash light trick
shine it at the dead screen see good data
yes, then the CCFL is DEAD< (or its power supply ,deep inside)
fixed may but would never do a 2003, not now.
lots of used good LED for sale,

Samsung 226BW 22" LCD wont turn on and flickers a blue light


Hello cstafford35,

Your monitor has a very common problem. The internal power supply has blown a part called a capacitor. If you are comfortable working with electronics and with soldering I can talk you thru the diag/repair. If you are not ready to tackle that we also offer a repair service, about $30 plus shipping for your model. Let me know if you want to try fixing it yourself and we can go from there. The repair will require opening the monitor case and replacing from 2 - 5 parts. You can call me at 318-447-9040 if you have questions.

Monitor flashes image for split second then goes blank but green LED flashes as well


while the monitor is still powered on, but with the LED flashing, unplug the monitor from the PC. press the power button, and the monitor should go off, now plug the pc back into the monitor. Turn the monitor back on and it should work.

Occasionally this will not work for me, but if I repeat it it normally works

Hope this helps - my problem is intermitant so it may be different to what u guys have
