Question about Electronics - Others

Shumacher x141b beeps constantly when device is plugged into it. Green light is on, red light is off. Also, fan is surging. It is putting out 110v.

New inverter. Haven't had it work right yet. Using it for RV refrigerator when on the road. 3.5A, 120v. Actual voltage is 110v. It's right at the limit of it's capacity. Batteries charged to 12.85v.

You're running more than the specified power. The refrigerator is an inductive load, which means the power factor Pf will be less than one. Consequently, the power draw from the inverter is Volts x Amps / Pf. Also, if the inverter voltage is less tan 120V, the refrigerator's compressor and fan motors will draw more current than the nominal rating. How much more depends on the motor design. The harmonics from the inverter (it has anon-sinusoidal input) may increase energy loss in the motors, especially if there is a fan with a shaded pole motor (common in refrigerators). The bottom line is that you are probably drawing at least 420 Watts from an inverter rated for 410 Watts. It's very close to shutting down on you, and may cause premature failure in the refrigerator.
I recommend getting an inverter with at least 450 Watt capacity, preferably with a true sinusoidal output, or harmonic content less than 5% under full load..

Testimonial: "This isn't a household fridge. It's an RV fridge with no compressor. It only has a small heater to heat the coolant. There is no surge. I agree, though, that it's running on the edge of the inverter capacity and that's probably the problem. thx"

SOURCE: batteries don't charge

Dust getting in the charger is a problem, Try blowing it out with a moisture-free dust remover, found at most any store. Green flashing means improper power, due to dust or power from the outlet, try a differant wall outlet. Red flashing means the charger or battery is to hot and must cool down before it will charge. The charger will not charge a battery if the lights are flashing. Solid Red light means it is charging and solid green light means it is charged. Plug the charger in first before putting the battery on the charger. If the charger has been droped or hit the floor the coil inside could have broke loose and dammaged the charger requiring it to be replaced.

Do you hear a clicking sound If not. there is a black box inside the out side door. Check the fuses in it.

Red light on and beep sound contionus came


Hi Subramanian,
If this is a small desktop UPS like the one pictured in your post then it is most likely overloaded. If you have a printer plugged into the UPS then try unplugging it from the battery backup outlet(s) and into the surge protection outlet(s). Other things to try would be to unplug connected devices until beeping stops... and a good away to narrow it down is by unplugging one device at a time to find the one causing the fault. If one device is the cause then plug that device into a surge outlet, another UPS, or into the building outlet -- if not then plug it back in and try another device until you find the one that is overloading the UPS. **There may be more than one device that is plugged into your UPS that is overloading it**
Hope this helps. If you would like more assistance please give me a call: 407.380.9200.

Computer won't start, solid amber light, no fans, no keyboard, nothing. There is power to monitor and modem. What's wrong and how can I fix it?


That my Friend is the Yellow Light of Death, anyway turn on Your PC, as it starts You will here some beeps especially on a Dells. Count the beeps , there will be a slight pause so it will beep once then pause then beep again. Count the beeps and that will be Your code. Go to Dell Support site and look up code. Most of the time a Yellow amber light means that there is trouble with Your Motherboard but thats not to say its the Motherboard itself, during a power outage with no surge protected, it could have possibly burned out Your RAM, Processor, Heat fan, even the power supply itself. So look up the code and at least You'll have a better chance of finding the solution, Good Luck

Light and fan work but does not work with wall switch


This would mean that that constant power to the fan and light is not wired through the switch right, or not wired into the switch at all. Most ceiling fans that have a light kit will have a Black, White, Green, and Red wire that comes from the ceiling and hooks into the fan and light. If it was done correctly, then the Green wire would be ground, the White is your neutral which is hooked to the other White wire, the Black wire is usually power to the light kit which will also hook to another black wire, and the Red is to the fan. Sometimes the Red and Black are reversed. If any of these wires are wired wrong, that could possibly lead to a constant power to the fan and light kit.

42 Philips Plasma 42pf5321d/37 green light on no AV no Menu nothi


I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung, Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Link to a photo of the PCB. Make a note of the location of all cable connections then unplug them all. Un-install PCB, Check a Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-1754-ND. Total cost was $7 with S/H. 2nd more of a long turn approach to your system. You might look at a Power conditioner to ensure constant clean Voltage & current to your Set, Price I know running about $150 to $200, but this will protect your set from a Spike and under voltage swings from the 110V plug. Surge protectors only help the Spikes on the 110v Line not the Drops. Hope this helps

Hardlocked;beeping and red light on motherboard;will not restart


Something on the motherboard has failed, and the RED light confirms it.
Turn your computer off.

Remove ALL of the RAM. Turn your computer on.
Do all the fan(s) start to spin?

Do you get the _same_ "beeps" as before, or some different pattern of beeps?

If it has more than one stick of RAM (and the RAM is _NOT_ labelled 'DDR2'),
then remove all but one stick of RAM, turn your computer on, and try to reboot.
Same beeps?

Turn your computer off, try a different single (or pair of) sticks of RAM.

Caution: before doing any of the above, your computer could be within the "WARRANTY" period,
i.e., it could be fixed/replaced for free!
