IBM OP500 Uninterruptable Power Supply

Hi Rachel , Can you find a model number on the door controller unit it will help us to search for a possible idea on the settings side of the solution to your unwanted problem.
Another possible solution may be to use a UPS on the controller. This stands for uninterruptable power supply. However long prolonged power failures may drain the UPS battery but it would work for short power interruptions (time depends on the standby power drain of your door controller and the VA rating of the UPS) and brown outs to the power lines. These are used on computers normally so a search on the internet for UPS or take a visit to a computer shop and they would source or carry a UPS device.

Intermittent activity may be associated with a disruption of continuity between the power supply and the video circuit board. Commonly the condition was damage from a power surge and for what it is worth; I strongly suggest that if your repair or replace the device; obtain a UPS rated at 1000 Watts. A UPS is a battery backup surge controller. Uninterruptable Power Supplly.

Buy a UPS "uninterruptable power supply" from a office supply store. Plug your pump into the UPS. When the power stops, pump will continue to run.

It won't be cheap because of the power a decent AC demands but an appropriately-sized "on-line" Uninterruptable Power Supply (UPS) supplies power from internal batteries continuously but when AC is available, the batteries are just paralleled to the line so any appliance plugged into the UPS never notices the power failure; at least until the batteries are exhausted. Since you didn't include the make and model, no one can tell you the backup capability you need or which voltage it requires (120 or 220VAC).

uninterupted power supply

first the correct model # is M61wh74s.
there are two differnet lamps that may have been installed at the time of manufacture. you should remove the lamp access door and use the lamp part # printed on the label pasted to the inside of the access door. To use any other or a sub (which are only good for about a year) will down grade the brill of the picture and cause undue load on the ballast (supply cirucit for the lamp). Additionally if you are in an area that experiences frequent brown outs (power reduction to the home) I strongly suggest using a UPS (uninterruptable power supply) to power your DLP TV.

Questions:
Did it just start, or has it happened before, if so, how often?
I've found that I have to reboot my Belkin router, usually daily!
What I've found was my wireless headphones were interferring with the wireless channels on my Belkin. I ended up unplugging my wireless headphones while on the internet, then plugging them back when I wanted to use them.
I even went into the router's software and changed the wireless channel to see if that would help, it didnt.
Things that I found to interfere with Belkin Wireless Routers:
1. wireless headphones
2. cordless phones
3. UPS (uninterruptable power supply), (SOME) for some reason it's emitting frequencies within the wireless band of the router.
4. Cable In-House Amplifier
5. Ive had two really weird ones, a microwave oven and a clock radio. I traced those by switching off circuit breakers, until the problem quit.
Work-around Solution, Ive had to move my router as far away as possible from these sources, or these sources away from the router, except of course my wireless headphones, didnt matter where I put it, it still affected the router. Hope this helps.

sounds like you have too many devices plugged in, it's not the ups that's failing it's the amount of power it takes to keep all you devices running. you may want to buy a larger ups or you can unplug some of the devices you don't need in the event of power outage. if it's just your pc your power supply might be sucking up alot of juice, i'd check and see what the power consumption rate is on that particular power supply.

Have you tried pressing and holding the off\on switch to make sure it toggles to "normal" rather than "charge"?
