Having problems with your Samsung SyncMaster 215TW 21" LCD Monitor ?
Screen flashes - samsung 215tw LCD monitor
\015 Screen shows no image with initial start up and screen power on. Turn off, turn on (screen flashes), turn off, turn on (screen flashes and stays on a little longer), turn off, turn on and then finally it stops flashing and displays an image. Is this an issue with the back-light? What type of servicing is required?\015
Walkstex, I will answer the last ? first. All LCD monitors WILL NEED to have their "cold-cathode-fluorescent-tubes" replaced!!! As long as your display had a Bright, Crisp image displayed on it before this "FLASHING" symptom occured, then you don't need new CCF tubes. Your problem seems to be occuring in the electronic ballast circuit called an INVERTER. It Takes 12-15v DC and turns it into 800-1200v ac to light up the CCF tubes. This is the same technology used in the new style curlieQ screw-in light bulbs called CFL's. Only difference is they use what is known as a CONVERTER circuit----AC to AC!!!! And the tubes hung horizontally on the rear of your LCD panel are thin and straight. So, to answer your first ? Yes, it is an issue of getting the CCF tubes to light up. (backlighting) Now, I should also mention that there could possibly be a problem with the main power supply in the monitor. It is called a "switch-mode-power-supply" (smps) that supplies DC for the digital signal processing board (typ +5v) and 12-15v for the inverter. Well, This typical type of symptom could be as simple as a thermally fractured solder joint on the power supply board or some bad Filter capacitors could also need replacing. I suggest that you search web to find out more about the things I have mentioned in the above text. Do search for things like "swollen capacitors", "Bulging Capacitors" and checkout www.badcaps.net for some pictures of typical failures. Get back to me if you want to carry this any further on your own. Bye for now. I'm louie12fix on fixya or lmistyrel @aol.com

I have a Samsung Syncmaster 932b LCD monitor. When I turn it on, the screen just flashes on and off, as does the blue light around the power button. I read up online and found that the capacitors on the power supply were bad, so I opened the monitor and found the power supply motherboard and I found 3 of the capacitors were bulging. I am looking to replace them, but I can't seem to find out exactly what kind of capacitors they are. The capacitors themselves have the following written on them,

My Samsung 943N LCD monitor will work for 1 second and then goes black. When I choose the extended desktop option, for example, it will flash my desktop on the monitor for a second and then go black. I have 2 cords that I have tried this with and it happens with both...and I have 2 computers I have tried it with and it hasn't worked with either...so it definitely appears to be a monitor issue.

Samsung Sync Master 914 has no picture. When power supply is only in, green light flashes slowly. When both power and vga are in, green light flashes more quickly. I hear a faint clicking sound coming from the LCD screen when out of case (located top right corner when screen side is down). Screen flashes faintly (only really noticeable in the corners)and coincides with the flashing of the green light (even with green light being unplugged.) No caps seem to have issues.

I would check the caps with ohm meter. Make sure they all show increasing resistance. Caps can be bad without looking bad. Check output voltage on the power board, should be around 12V. If all that checks out then I'd look next at the backlight bulb. ... Computer Monitors
