My Electrolux EIFLS20QS front load washer keeps giving me an error: Unstable mains supply. I've tried unplugging and switch the breaker, it will start again but then the error will come back.


Unstable mains supply means that power supply voltage is too high or too low or frequency is out of limit. Usually it is enough to wait for nominal power supply conditions. My suggestion is to measure the voltage and frequency on the wall socket where is attached washing machines, also is a good idea to try to connect a washing machine to power supply by an extension cord from other rooms (different phase) or from the nearest neighbor in order to eliminate wrong or disturbed power supply line, otherwise the main board is defective.

My sansui rear projection tv's picture is concave with convergence problem also how can i fix it


The convergence can become unstable if you have a failing colour wheel if a dlp set. the same thing can happen if your lamps is beginning to fail the poor frequency of light from bulb disrupts picture. Convergence is usually done by entering service technician code into set through the remote and entering the engineering sub menu and if you don't know what your doing or have a colour pattern generator you could make things considerably worse .

I have a Kicker Solo X 12" that plays fine when I have the volume at low or middle level and when I turn it up, the sub gets a large boost of power but only outputs a loud high frequency bassy hum until I...


Either your amplifier is faulty or it's not getting enough current. I think it's not getting enough instantaneous current and is unstable for that reason. check all connections and earths are tight

Galaxy dx 2517 frequency drifts sometimes on recieve and sometimes while talkng freq will go both ways up and down


The mixer crystal is unstable. It may need replacing. Some times you can reset them. Take a soldering iron and heat up the mixer crystal up for about 5-7 seconds. See if this stabilizes it. If the radio still drifts,then you need to replace the mixer crystal.

Unstable connection


ome wireless networks based on the 802.11b or 802.11g standards transmit their signal in a narrow radio frequency range of 2.4 GHz. Various other electronic devices in a home, such as cordless phones, garage door openers, baby monitors, and microwave ovens, may use this same frequency range. Any such device can interfere with a Wi-FI home network, slowing down its performance and potentially breaking network connections.
The 2.4 GHz Wi-Fi signal range is divided into a number of smaller bands or "channels," similar to television channels.Many wireless products ship with a default Wi-Fi channel of 6. If encountering interference from other devices within the home, consider changing the channel up or down to avoid it. Some Wi-Fi channel numbers overlap with each other. Channel 1 uses the lowest frequency band and each subsequent channel increases the frequency slightly. Therefore, the further apart two channel numbers are, the less the degree of overlap and likelihood of interference.
If this won't work, Then consider buying a new wireless router as your current is deemed broken.

Helloi bought a new TR2424-230-50 inverter and 2 X 12V batteries connected. When charging with my 5KVA generator the generator frequency is very unstable and the amps (a/c) drawn is upto 10A. Is there a...


Frequency is a function of generator RPM. Slower the engine, lower the frequency. Faster the engine, higher then frequency.

Look at your generator first, it should be able to maintain this load without problems - check your governor.

You can try plugging in a lamp directly into the generator so that it won't see a pure inductive (input to inverter) load, but will also see the resistive load from the lamp.

Power Draw of 10Amps is going to be what it is, unless you change the AMP Hour capacity of your battery bank that is connected. Be careful though, as this will not only reduce the charging current (and amount of load present on the generator), but it may also affect how the inverter operates with heavy loads, and may cause the charging profile to go into bulk and float modes prematurely.

Are you feeding your generator into the inverter via the transfer switch, or are you plugging the coach power cord into the generator? The former would force all the AC loads to be switched by the inverter, the latter allows all ac loads to be powered, even those that you may not know about / realize (water heater loads are a big one) and eat up generator capacity.

Unstable frequency


check your governor and linkage for build up of dirt and grime. You should be able to move the governor by hand, with some resistance from the springs. The governor arm should not rotate about the shaft protruding from the engine.

If governor seems to be in order, and engine cannot maintain RPM that it needs to (hunts), look towards the carburetor being fouled (clean out best you can, but don't soak since it is an EPA carburetor), air cleaner dirty (replace even if looks good), or loss of compression (check with compression tester, should be around 90 psi or better with engine warm).

I have a new Toshiba of Model No Satellite L310. It,s unstable on screen, exactly, when i open some Website more shake, pls help me , how i should do my Laptop? thnks


Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} By “it’s unstable on screen” and “more shake” do you mean that the screen is freckling?

1. Lower your screen resolution....
2. If you have any frequency sending of receiving device Like mobile near you Laptop keep it at a distance like 2 feet…the frequency affects the screen.
3. If you are connecting to the Internet through a wireless Modem, that could be a reason. Please try to reposition the modem to a location that’s not affecting your screen.

Hope this helps …

VGA Cable max Length from Laptop to Projector


Your on the edge, possible that the image will be unstable (wiggly). Considered a VGA amp from Gefen to up the drive. 50ft is about max. You can try dumbing down the res if it is unstable. Less horizonal frequency to travel long distance. good luck
