Wiring
Check your power cord and power supply, check the plug is clean and free from corrosion or dirt.
Plug another appliance into the same socket to check there is power at the socket.
Note: Electricity can cause serious injury even Death.
Isolate your power supply from the mains switchboard.
Switch off and Unplug your appliance from the wall socket before attempting any repairs.
If its still under warranty, take it back to the store or manufacturer for replacement.
Call a serviceman to test the appliance for you,
If not you could...
Check your fuse in the device, you will have to dismantle the appliance.
Get your Multimeter and do some tests...
Test the flexible cord connections
Electrical tests included, visual inspection, Earth continuity, Polarity and Insulation resistance.
Examining cord for Damage
Disconnect flexible cord from power supply.
Check cord along the whole length for obvious damage
1: Visual Inspection
A visual test is necessary before using test instruments to ensure that all specific safety requirements are meet.
Check the general condition and safety of the cord, plug, cord anchorage, terminations and of the appliance itself.
2: Earth Continuity.
The earthing system of an electrical installation must be installed in a manner that will allow circuit protection devices to operate if there is a fault between live parts (other than Neutral) and the mass of earth.
What to check: For class (one) 1 protectively earthed appliances only, test for very low resistance between exposed appliance metalwork and the earth pin of the plug. this resistance should be as low as possible and must not exceed 1 ohm. Note: the Exposed metal parts of a class 2 double-insulated appliance must not be earthed.
Equipment requirements:
A Multimeter (Digital or analogue) Set on a ohm scale or an insulation tester that also has a continuity scale.
A set of leads.
3: Polarity
Why is this test necessary:
An incorrect connection of phase and neutral conductors to fittings and appliances is extremely dangerous and has been the cause, either directly or indirectly of many shocks and fatalities.
What to check:
Polarity tests are carried out to ensure that every single-pole switch operates in the active conductor or the circuit in which it is connected.
Equipment requirements:
A Multimeter (Digital or analogue) Set on the resistance scale when the SUPPLY is NOT connected.
or a voltage indicator set on a suitable voltage rating when the supply is not connected.
4: Insulation Resistance
Why this test is necessary:
All live conductors (including Neutrals) and live parts must be insulated to prevent - Electric shock hazards from inadvertent contact.
- Fire hazards and equipment damage from short circuits.
What to check:
Insulation resistance tests must be made between:
- Active conductors of a poly-phase circuit
- Active and Neutral
- Active and Earth
- Neutral and Earth
The insulation resistance between appropriate components shall be not less than 1 mega-ohm minimum
Equipment requirements:
An insulation resistance tester which maintains an output of 500 volts when loaded with a 1 mega-ohm resistance.
A set of leads.
Different countries adhere to spicific Electrical (safety) Regulations and standards
This information is only intended to enlighten the novice, guide and remind someone already in the field of electrical installations.
DO NOT attempt any electrical repairs unless you have the appropriate background or training.
Top 2" of my concrete wall has eroded. How do I
Hi. There are different kinds of concrete coating. The choice of product varies, depending if the wall is interior or exterior and on the location of the wall (for example the product used in a bedroom's wall will be different from the coating adopted in a garage).Epoxy coating are great products that can be used in exterior or interior. Epoxy products however may smell and trigger allergies. Epoxy is one of the strongest coating for exteriors.If the space is a living room, then it is probably better to use acrylic cement. Acrylic coatings do not smell and do not release volatile compounds. Acrylics look similar to Portland cement and are generally less strong and adherent than epoxy paste. The application method is usually illustrated in the coating product's container. The procedure consists in cleaning the wall (you can use a power washer), applying the product with a trovel, and then checking the results after 24 hours or when prescribed in the coating's instructions.After applying the coating you can finish the wall with paint and sealer product.
Fm doesn't function until the unit get warm enough
Hi,
Does receiver give noisy sound in FM or remain silent until it gets warm up?
Problem seems with FM tuner in receiver.
Let me know your findings about receiver sound of FM mode to diagnose possible cause of problem.
Thanks.
My Yamaha RX-V757 Receiver wont
There are internal fuses in this unit.
Check these fuses first.
If you find a fuse that measures open, and the glass isn't black or black/silver then simply replacing the fuse may do the trick.
Make sure you get an EXACT match for the fuses, some are slo-blow because of the power on surge it has to allow.
Why does my system cut out at high audio levels?
There is not enough power output coming out of the amplifier and the overload switch kicks off. Sometimes this can be caused by cooling. Check your venting in the back for dust build up. Hope that helps!
My receiver shuts off at a certain volume saying
Here are a couple of common causes for this... You may indeed have a wiring issue between the receiver and speaker(s) - i.e. wire damage causing the conductors to touch each other (look for wire problems at the back of the receiver or speaker(s) right where the wire connects to the device). Also check for physical damage like pinched wire, damaged or missing insulation, etc. The speaker(s) could be damaged (possibly from excessive power/volume levels). If these are not the problem, the cause may be the receiver itself. Try disconnecting one speaker at a time and running the volume back up to see if the receiver shuts off. This may help isolate a specific wire/speaker to check.
