Almost my whole PC system is hooked-up to 1 AVR (automatic voltage regulator). This AVR somewhat also acts as the main switch.

After Windows shut down I turn off the AVR switch and my CPU is totally off. My monitor I/O led light turns amber from green. Takes awhile to totally turning off, but its does after a few seconds or a couple of minutes. Must be some residual electricity in the CRT.

Otherwise you can push the Viewsonic G220f I/O switch to instantly and totally turn off said CRT. Please don't ask me why - I honestly do not know the reason why. I just observed it to be so.

Problem solved! The main power thingy (the thing with the big red wire coming out of it) was all black and dusty. There was 'soot' all over the whole insides of the monitor. I concluded that this monitor should be laid to rest, and a new flat-screen monitor erected in its place.

THe problem is in the set top box. Or common called the tuner box. IT looses the 5 volts to the main display and thus the monitor will go into a shut down state. THESE boxes are factory repair only and must be sent off to repair.

I have a Graco baby monitor, it started making a noise for the last 2 days, could it be a battery problem (even with power connected)? The monitor is about 1.5 years old.

Annoying! happens to us too frequently, but this works. We ended up buying a new one and returning our broken one after owning for three months From Manual:) 5. Turn on the Nursery Unit using the On/Off switch on the side. The green power light should come on. 6. Within a few seconds, the Parent Unit will lock on to the Nursery Unit and the top four (4) green LEDs will shut off. A second later, you will hear a series of beeps and the connection LED should change from red to green. Your monitor is now ready for use. 7. If the top four (4) LEDs do not shut off, power off the Parent Unit and the Nursery Unit and repeat steps 4 and 5 above. 8. If the connection LED on the Parent Unit does not change from red to green and the unit begins to beep, press the channel "ch" button on the Nursery Unit. Within a few seconds, the Parent Unit should lock in on the Nursery Unit and the connection LED should change from red to green. You may hear an audible beep during this process. 9. If the Parent Unit is still unable to lock in on the Nursery Unit (connection LED will be red and the unit will beep), power down both the Parent Unit and the Nursery Unit. Wait for 10 seconds then hold the volume down button on the Parent Unit while pressing the On/Off switch. When the unit powers up, you will hear a single beep and all of the soundlights will illuminate. Release the volume down switch and within 2 seconds you will hear two beeps and all of the Sound Light LEDs will stay lit and the bottom LED will be red. 10. Repeat steps 5

Turns off immediately after turned on

Do the self check it should have: when shuts down and green light goes out: On the front of the set press and hold both input and menu buttons at the same time for at least 5 seconds and then release both.

Power light on set should blink a two digit error code: like 2 blink,2 blink, pause and repeat it at least 5 times total.

Let me know what error code and I will tell you what it means.
