Hello there,

It sounds like your Power management system has a problem. Your monitor under default is told to go into standby after 20 min. I would suggest that you disable your standby.
You do this by going into your
Control Panel,
Power options,
and under power options
Turn of monitor (you select disable) and under
System Standby (you select disable, do this only if the first setting doesnt work).

Good Luck!!!

Could be getting too hot. Make sure all fans, cooling fins, heat sinks, HDD vents and weep holes are unobstructed and clean. Many computers have a BIOS screen at startup that will display system temp. Start it up and enter the BIOS, check CPU temp. Most PC's will shutdowm or reboot if temp exceeds 140 (this can be adjusted).

If not overheating, could be fault in a memory module, HDD failure, or CPU itself. But that's not that common in the scenario you're talkin about

The power light is constantly blinking in yellow. before this happened the yellow light was on without blinking I turned it off, once I turned it back on the light turned green but the screen...


try unplugging your t.v for 10-20 seconds. plug it back in. if your power light continues to flash your t.v is the issue. you should be able to google your issue or check your owners manual about the problem. unplugging the t.v is the last ditch effort. Good Luck!

My monitor is not responding to anything. what can i do aside from rebooting?


do you see the light blinking in the monitor? I mean the POWER led light up? If so, then the monitor is ok and is working good. It is your CPU which has a problem and not sending digital signal for the monitor to display.
Try to turn off your computer. After 3 minutes turn it back on. then notice if you will hear a short beep from the CPU. That signals a successful video initialization. If you went through that process, then your computer will get back to life.
However, if you dont hear a short beep from the CPU, then definitely your CPU is frozen therefore there is nothing to display to the monitor.
You need to open the CPU case, pull out memory modules then plug them back in. Then try booting.
If not successful, try to open case and pull out the processor. Put it back in after 30 seconds. Try booting again.
Do ALL THESE while your PC is UNPLUGGED.
Good luck.

Monitor looks as if there is no CPU


If the power supply is coming to CPU before activation of CPU then it must be receiving current from UPS. Don't try unplugging, You may get shock. Thank you, Sir.

Monitor problem


erickalin - it sounds like your computer might have shut down and failed to come back up again. If you have access to another monitor, try hooking it up to your computer instead of the one you normally use (that won't stay on). If the second monitor won't stay on, the problem is your computer. You might have to take it to your local computer geek or computer store to get serviced. If your computer DOES work with the second monitor, you might need to have your monitor serviced or replaced. Good luck!

supposed2b, I think you have the same problem, although your computer doesn't even sound like it's powering up. Your power supply might be faulty or an internal component (CPU or memory most likely) of your computer has died. Double check your power connections and ensure that when you press the power button you hear the computer start up and the light on the front comes on (hopefully green or blue, but not yellow or red). Again, you might need to take your computer in for service.
Good luck!

Monitor goes to white at cpu shutdown


The problem is in the "soft switch" technology: On some of Sylvania's newer monitors they have incorporated what is called "soft switch" technology. This allows your ATX power supplied computer to turn your monitor on and off using it?s software controls. Therefore, your monitor?s light will always stay on blinking even when your computer is off. The monitor in normal operation consumes about 80W of power; in the "OFF" state it will be reduced below 8W. The "OFF" mode of the monitor can be controlled by the PC input signal or by pushing the soft-power button to disable the PC signal control for manually turning off the monitor screen. Thus, when the monitor is in soft-power "OFF" mode it still consumes a very small amount of power. For the purpose of making it noticeable to the user that the monitor is in soft-power "OFF" mode, we designed the power indicator to provide for a slow blinking signal (every 2 seconds). If you need to totally turn off the power, then the power cord would have to be unplugged. The same is true of the PC itself, but the PC does not provide for notification while in "OFF" mode. Your monitor looks like it may be in need of repair, contact info: PTI Technologies Inc. 7372 Doig Dr. Garden Grove, Ca 92841 Phone: 714-799-3899 Fax: 714-379-6290 Hours: Mon - Fri 8:00am to 6:00pm PST
