Question about Computer Monitors
I have Samsung Syncmaster 2232BW which has been great until today, now whenever i switch it on it displays properly for approx 2 seconds and then goes blank. If i press the menu button the menu comes up very faint as if there is no lighting from the back. switching the monitor off and on produces the same effect (picture for 2 seconds and then blank)
Does anybody have any ideas about this?
i just finished repairing a 20 inch acer monitor that had the same issue.... you have to take it apart and examine the power supply side of the monitor. there are capacitors that go bad on that board. you can tell be feeling the tops of them... the feel rounded. replace the capacitors and put it back together and it will work fine

Sounds like you may have had a power surge.??
Disconnect power and signal input.
Turn the unit off for 20 minutes or so. Check the outlet against another device. ( Light )
Turn unit on without connection to PC video.
If you get a no signal, you good to go . Reconnect. If you continue to get a flashing light on power button,
Check warranty, get it back to Samsung for repair.
Hope this has helped

check your power supply and power cable and check your monitor cable if its not damaged..or try your monitor to another computer..

m_r_murphy, The T220 may have developed an internal ac to dc "switch-mode-power-supply / CCFL inverter supply" power problem an you may need to need to have it repaired, Look into warranty or outside technician to refurbish the unit's SMPS/inverter!!! From your description, I believe that the SMPS is in "partial shutdown" mode!!! (no 12 to 14v dc) to power-up the "cold-cathode-fluorescent-lamps" that enable you to see the text and graphics that you already know are being displayed on your lcd panel!!! (+5vdc or 3.3vdc rail still alive!!!) You have "black screen" symptom!!! NOT BLANK n BLACK screen!!! There are lots of DIY videos on YOUTUBE to help you decide if you can attempt a cheap (<$20usd) repair to your unit. Do some reading in my old fixya profile (louie12fix) and visit some of the links you find there. Because your T220 isn't any different than any other brand of CCFL back-lit lcd display in it's basic design and operation you should be able to fix it. Get back to me lmistyrel on aim or do additional comment to this original post here on fixya with info on your next step to repair this unit.
All the other ccfl back-lit lcd monitor tech's on fixya already know what's wrong inside your unit!! Do your research first!! Bye for now, 12fixlouie

I have the same problem its defenitly a problem with the lcd monitor not with the graphics card nor the pc. I hooked up the digital and afterwards the vga connection both had the same result. 1 s perfect screen all visible but than black. pushing the on/off or standby button again shortly 1s the display works than it blanks. Did the same test while connected to a dvd player via the composite video... same problem . Since the previous posts are that old and without a solution I guess there is no hope in getting it fixed.
