Re: Display flckers on and off
Are you able to test this monitor on another pc?
This "might" be a graphics card problem as some Nvida cards have problems identifying certain monitors and continually referesh them.
This could also be a sign that there is a power problem inside the monitor.

I have a problem with my MW512AU. Sometimes it drains after wash cycle, but sometimes it sticks when it goes to spin, doesn't get up to speed, water comes on for about 10 seconds and shuts off, and it tries to spin again. If I hit the wash progress switch it goes directly to final spin and works ok. I then have to run a 2nd wash cycle to rinse the clothes. I also noticed a buzzing sound when I turn on the power point, which lasts about 3 seconds before stopping. It will come back on every 3-4 minutes for 30 seconds. This is with the machine power switch off. It powers on normally.
shaylane_195, Good description of problem! But you left out one or two key things to tell me. Age of monitor? Approximate total "ON" hours of use? Is unit covered by LG (Lucky Goldstar) warranty? You and only you can tell me if the screen is really BLANK, or is it only BLACK? Do flashlight test to determine true state of screen! Can you see very, very faint image of WIN-desktop holding bright flashlight near your black screen? This monitor works!!! You just need to fix the possible (1) "cold, frosty looking, thermally intermittant solder connection on the "internal switch-mode-power-supply/CCFL inverter board. Yes, your monitor along with many other CCFL back-lit LCD units of all brands also could have some BAD, swollen, leaky electrolytic filter capacitors installed on the SMPS/CCFL inverter board which will need to be replaced with new ones of higher quality. Get back to me, lmistyrel on aim. or do additional comment on fixya, after you do some reading in my and other fixya tech's profiles to discover all options you as consumer/user have open to you. Bye for now. 12fixlouie
You don't have a short-circuit. That would have blown the protections or even the monitor. Refer to the manual, that flashing light may be a code that tells you the problem. I don't think the repair would be expensive...
The start up problem is common and will only get worse. Call Samsung as these monitors have a 3-year warranty. No receipt? They will accept your word regarding your purchase. I have
two that failed exactly the same way. I called 1-800-SAMSUNG and they
gave me the choice of an exchange pair sent directly to my house
(requiring a temporary credit card deposit) or by having the exchange
pair sent to the UPS store where I would swap out my bad units. No
receipt. They merely asked me when I purchased it so they could have
it for their records. Manufacture dates such as your (March '06) and a
purchase of September '06 are not far fetched at all. .
No sync means no video signal to the monitor. The rest sounds like a corrupted OS. This could be from a number of reasons, including a virus. If you have NORTON or MacAfee, Your open to a lot of attacks. Get AVG free, and use Mozilla instead of IE.
The reason the fans come on full speed is the MB senses a high temp on the CPU, until the bios fan control takes over after POST. This is normal on most systems.
