Check and replace its main power regulator board inside. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electric shock. Instead, contact any experienced service technician, or the nearest service center.

SOURCE: no power - have checked fuses, power leads and master switch

Well yes, there a problem in the power supply modual.
It does sound like a failing power supply , becuse of the
fact you don't get charge up spark from the plug , wich is normal
affter it's been off /unpluged for 20 min or so .

check the resistance of the plug coming from the set with a volt meter if you have 10 meg ohms or higher,
it's an open circuit and more than likely a 1.50 fuse in the power
supply. If the fuse blows instantly then it's a shorted output transistor or rectifier diode in the switching power supply.


Be a shame to pay 300.00 plus for a stupid fuse.

hope that helps a little . if you have any questions just comment
an i'll respond
.

Why doesn't my SANYO TV turn on?


a general check list to run through:
1. is the tv plugged in to the wall socket?
2. is the wall socket switched on?
3. is there power going to the tv (is there a light on the front of it where you point your remote)?
4. Does your remote have batteries?
5. Do the remote batteries have enough power?
6. Does the tv have a manual power switch that u can try instead?
7. are the volume, color & brightness settings all turned up?
8. Is the cable (satellite) plugged in?
9. are there more than 1 cable plugged into the tv? (perhaps they are swapped around?)

If all of the above are in order, you may have had a brown out (a power surge) that could possibly have overloaded the tv's circuit.

Insignia tv, will not power on. no lights are on


Try using a different room. The sockets will probably be on a different circuit. If that doesn't work, it sounds like a power supply problem on the TV. You'll need to replace the part. Unfortunately, it's usually cheaper to buy a new Insignia tv than getting the power supply replaced. TV technicians are expensive

The wires come off the pump so i put them back on now i got nothing working


Also,
please note that all electrical wiring and installation details given on diydata.com is for information purposes only. From 1st January 2005, the Building Regulations Part P requires, in England and Wales, that only certified persons can carryout electrical installation work, or the work must be certified upon completion - see this page for more details.

Ring circuit

(1) The ordinary wall sockets around the house are normally connected to a ring circuit (also referred to as a ring main). The ring circuits of a domestic property supply the socket outlets and fixed appliances in the premises.

(2) The 'ring' is formed by the cable going from the consumer unit to the first socket, then on to the second socket and then the next socket etc. until the cable returns to the consumer unit. This means (in simple terms) that every socket on the ring circuit has two cable routes back to the supply. The cable of the ring circuit consists of a red (live) wire, a black (neutral) wire and a bare copper earth wire, all three being enclosed by an outer PVC sheathing. The cable used in domestic ring circuits is either 2.5sq mm or 4.0sq mm twin core and earth, these are rated (in free air) at 24amps or 32amps respectively.

(3) Each ring circuit is protected by a 32 amp fuse or trip fitted in the consumer unit. Modern installations incorporate a Residual Current Device (RCD) before the consumer unit which trips the whole system off if a fault is detected.

(4) In older houses the cabling for ring circuits (and other circuits) may be fed through the wall cavity with the cables coming into the back of the wall mounted socket. This is unacceptable in new premises and extensions. It is now considered that cables within the cavity may become wet causing the insulation of the cable to break down and moisture running down the cable into the socket. When rewiring older houses, new cables should not be run through the cavity, they should be run through new ducting embedded in the inner wall surfaces or under floorboards.

(5) A ring circuit is considered to be rated at 30amps (7200 watts). A ring may serve up to 100 m sq of floor area and, in theory, may have any number of sockets outlets or fused connection units connected to it. With each socket outlet is normally rated at 13 amps, as a 'rule of thumb', they are limited to under twenty outlets, it is unlikely that the variety of domestic appliances being used at any one time will exceed 30amps. The length of cable used in a ring circuit is limited to 50 metres for circuits protected by an MCB. The sockets are normally mounted flush with the wall although surface mounted boxes are often easier to fit when sockets are added to the circuit. .

(6) High power electrical appliances (such as cookers, showers etc.) should not be connected to a ring main even if they use less current that the 30 amp rating of the ring circuit. Connection of such appliances will reduce the number of other appliances that can be use simultaneously and will lead to nuisance trips at the consumer unit.

(7) It is advisable to have at least two ring circuit in all premises, in multi floor houses, one for each floor. The kitchen may have a large number of electrical appliances so a separate ring circuit for the kitchen may also worthwhile, this has the added benefit that a freezer will not be affected if there is a fault elsewhere. A single ring circuit should serve a floor area no greater than 100sq m (or 120sq yd).

(8) In the UK, plugs used on a modern ring circuit have square pins and each plug is fitted with either 3 or 13 amp fuses. The correct fuse should always be fitted to suit the appliance, 3 amp fuses for appliances rated up to 750 watts, (lamps and clock radios etc.) - 13amp fuses for larger appliances up to 3000 watts.

(9) Spur extensions can be connected to the ring circuit. A spur is a socket connected into the ring by a single cable run so the socket does not have the full benefit of two cable routes to the consumer unit. Spurs are often used when a socket is added, it is easier to connect using a single cable rather than extending the ring circuit to include the new socket. A spur extension can be connected to the ring circuit provided that it supplies only 13 amp socket outlet (although that can be a double socket outlet) or one fixed appliance. Over the whole ring, the total number of spurs must not exceed the number of socket outlets directly on the main ring. No more than two separate spurs may be connected from each outlet on the ring.

Removal of the front of a wall socket will give an indication of the circuit connected to it:

A single cable connected to the terminals indicates that it is an existing spur.
Two cables may indicate either that it is on a main ring circuit OR that it is a spur with another spur connected to it. This is not a recognised configuration but possible if both spur sockets are single sockets.
Three or four cables normally indicate a socket on a main ring circuit with one or two spurs running from it.
If the wiring has been changed by a previous diy'er, it may be possible to identify any added cables and then deduce the original circuit.

Ring circuit fused outlet units

Where connection to a fixed appliance is required, a fused outlet unit may be fitted to the wall (rather than a plug socket) and connected into the ring main. These outlets require the correct fuse rating for the appliance and are connected to the appliance by a cable or flex. The outlet may be switched or unswitched and may be fitted with an indicator light to show when the supply is connected.

Where a flex is taken to a heater of any sort (e.g. night store heater) the flex must be of a special 'high temperature' type suitable for the elevated temperatures encountered. Use of ordinary flex will result in the insulation breaking down causing the flex to become dangerous.

A clock outlet is a similar type of unit, but with a small fuse fitted in a special plug connected to the flex. The plug may be retained in the socket by a screw or knurled thumbscrew. Though called a clock outlet, they are also suitable for other small low current appliances such as extractor fan units, door bells.



High Power circuits.

Within domestic premises, there may be a number of high wattage appliances, the most common being an electric cooker, immersion heater and electric shower. Each of these appliances should be connected to the consumer unit using a dedicated fuse/trip and cable run. The installation instructions for the appliance should detail the wattage of the appliance (which will also normally be shown somewhere on the appliance), the amperage of the fuse/trip and the size of cable required. Any switches on these circuits must also be of a suitable current rating. Source(s): http://www.diydata.com/planning/ring_mai...

I have a 42 inch Vizio tv and moved it to the bedroom from the den. I hooked it up to the cable (sat) like it was in the Den and it blew a cable line out. The socket was updated but now the tv plug got hot...


'probably the main transformer, bridge rectifiers, fuses, on the tv power circuit are damaged......along with some other components. Depending on the level of damage the board may, or may not be repairable. If so you may want to get a tv technician to install a replacement power board.

Wont come on


Instead of just unplugging the TV, perform a power drain:
1. Unplug the product's power cable so the device is not grounded to the house. 2. Press and HOLD the product's own power button for 1 minute to drain the capacitors. 3. Plug the product back into a wall outlet and try to turn it on.
Note: This procedure works with battery operated devices as well so remove the batteries and hold down it's power button.  Electricity can remain in capacitors and on circuit boards enough to prevent normal functionality. By clearing the residue electricity, your product will have a fresh start and many times this will resolve a buggy or non-responsive device that appears to be dead.
If the TV still won't turn on, then it appears something is wrong with it's mainboard since the TV is still receiving power because the standby light is still coming on.  The cost of fixing an older TV's mainboard could be costly or impossible if the part is discontinued.

Speakers won't turn on


Have you checked the fuse in your plug. If the fuse has blown it won't work in any wall socket. Change the fuse for a new one anyway, then try again.
