    Yep, Samsung 225bw. I've got 2. One (the older of the 2) when completely powered off, will often flicker, then go black (starting on the left side). I got it to work and then left it going for several months. No problems, but I've recently moved, and haven't gotten it to stick on this time.

My samsung syncmaster 73nw,when i turn it on i can use it well but aftr 5 minutes the m0nitor turns off, and aftr 3 mins it turns on,can u pls tell me whats wr0ng with my m0nitor?

You have bad Capacitors on the power inverter section; These 1000 uF 10V& 470uF 16V Caps will function half blown. As soon as they warm up the Cap either opens or shorts and takes down the power inverter. The venting on this monitor is very poor; To verify take a fan and place it behind the monitor, then try it again. If the monitor runs longer you have verified your problem. TCC

My husbands monitor keeps switching off

I had this exact same problem. The monitor kept switching off shortly after turning it on. I found a shorted capacitor (1000uF 10V) in the power supply. Replaced that and now it works fine.

Screen comes on gray with bars and then turns white. after several reboots it works.

the fault is that your monitor gets to work after the set gets the possibilitty that some components are thermally related is to be found out.
Open the monitor and use a hair dryer to warm the sections , power supply and drives, then switch on. repeat to other areas till the monitor works fine.
Now if you have a freeze it spray use it on to cool instantly. Now see if the fault comes back. If so the component can be isolated.
Look our for dry soldder joints in the board , loose connection, dry IC pins. Also check if some electrolytic capacitors can be large or small values in power supply and drivers to be faulty.

Monitor needs a long warm up time before ready to use. computer turns it on but it blinks off. after about 10 to 15 minutes the monitor will stay on.

Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what goes wrong:
Post back what you see inside so we can guide you further.

Monitor will not turn on including power switch

I suspect the power supply for the monitor. Try a power supply from a working monitor. If you have a used computer store nearby, take your power supply to them and try it on another monitor.

There is no need to turn off a monitor using its power switch. Monitors automatically go into standby mode when they are not receiving a signal. In standby mode they use less than one cent of electricity per day. If saving electricity is your goal, raise the temperature in your home by a degree and run the air conditioning less.

Dell E151FPb 15" LCD with power LED blinking.

The problem may be a loose connection. When I turn on my monitor, the green light blinks and a flickering white screen appears for a brief second every time. There must be a loose connection on the power board which may be causing this. The easiest solution is to tap at the back of the monitor. This will reconnect the loose end and the monitor will work fine until it gets disconnected again. I will open my monitor soon to find the real problem. But it will take some time to find it.
