Then teh power light slashes abootu every 10 to 15 seconds. I have tried to unplug the unit and plug it back in and try the sequence all over again but to no avail. IS their a reset switch or fuse that needs to be replaced.

    The solution offered was too general. Where is the power supply fuse? What kind of fuse is needed? How do I get to the power supply. Also it is a CT36HL43 not a 38 as I earlier posted.

This suggestion is only if yr panasonic is a Cathod Ray Tube kind. most times what causes such problems could be as a result of a dead Horizontal Transistor thats located around the lines transformer. but losing a CRT could be disastrouse i suggest also u give it to an expert other wise open the case of the CRT use a screw driver to discharge all power capacitors by bridging the 2 legs together. then carefully remove the yoke from the CRT.
NOTE:
to identify the Horizontal Transistor, it is normally attached to a heat sink and close to the lines transformer and is usually the biggest Transistor around the lines transformer.

To identify the lines transformer, the thick cable with a cap thats removed from the yoke is directly connected to the lines transformer

Transistors r electronic components that has three legs(pin) normally label Q with some smaller label like B(base), E(emiter), C(collector)
so try it out
that is if itsd a CRT.
hopes this helps
thank u

It must be power supply board problem. If you are not familiar with such repairs have a person to help you inspect board for bad electrolytic capacitors blown resistances etc. and replace if needed. In general electrolytic capacitors over 100V must be replaced.
Insert also your model no at link below to look for a service manual.

If this is a CRT TV, then I'd say that you probably have a failing flyback, or an issue with the power board. If it is an LCD or Plasma, the it is most likely the power board.

However, it is very difficult to say precisely, without conducting tests on the TV. Probably just replacing the power board might resolve this issue, however, I do recommend consulting a TV repairman, as they would be in the best position to diagnose the problem and provide a fix.

In any case, I wouldn't recommending opening up the set if you have no prior experience, as it can be dangerous.

If your TV is still under warranty, its best to contact the shop or the manufacturer in this regard..

Where does the wires hook from motor to where? Automatic Doorman 455


Is the door opener motor bad? You say, "the wires"--is there a plug on the end of the wires that can be plugged into an outlet? If so, thy plugging it into an extension cord instead of the outlet in the garage ceiling and see if you still trip a breaker. If you do, it's a problem in the opener. There are things to do to locate the source of the problem. It the breaker trips instantly when you press the button then there's a dead short somewhere. Does the motor get warm or hum before the breaker trips? If so, then maybe the door mechanism is locked up and the motor cant turn. Did you check to see if your garage door is locked?

Is there a fuse or breaker on a Panasonic CW1803SU Air Conditioner?


If there's no power up on the unit, you can check your breaker switch box to see if there's any tripped breaker switch. If so, turn it off, and turn it back on. In some cases a sub-panel is installed somewhere else to provide power to the unit. Normally that's where the breaker switch will be in that scenario. If after doing that it keeps on tripping it, or it just won't power up, then you might have some electrical components inside the unit that might be damaged, like a capacitor, or the compressor itself. Sometimes when the compressor breaks it stops turning and overheats, causing other parts to burn also. To fix this you will need to call a professional.

Tv will not turn on


let's try a hard reset of the TV. To do this, disconnect the set from power then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the TV back in, and also make sure the power cord connection to the TV itself is secure. Then press power once . Hopefully that will do it. If not try contacting:

I have a crazy fit massage machine that comes on ok and you can program it but as soon as you press the start button it trips the electric anyone any ideas ?


You have it plugged into teh wrong breaker possibly, see what breaker in you power box controls the washer, and plug it into an outlet that uses a bigger breaker, possibly 35AMP or so.

NO POWER TO UNIT


Is there power to the outlet itself?? If not see if you have a GFCI (ground fault circuit interupter) outlet near by ( it is an outlet that is usually shaped different than the other outlets) this outlet has two buttons on it "trip" and "rest" press the "rest" button this may turn the power on to the coffee outlet.If still no power, check to see if the breaker in the house power panel is tripped, if so rest the breaker by moving the switch on the breaker to the "off" position then back to the "on" position. This should reset the breaker, it trips again there is a problem that needs a more skilled person to assess. If this doesn't work there could be a problem with the coffee maker itself and unless you have the equipment to test and repair this you may be out of luck.

How to reset Cutler Hammer 1 pole 15 Amp


Turn handle to off position and then back on. Same as any other breaker. The red test button can be pressed which will trip breaker. If it trips immediately,unplug all devices on circuit and try to reset. Reconnect each device and see which trips breaker. If this goes to outdoor receptacle, check behind cover for moisture.

How to manually reset an AO Smith 2 hp motor?


If you did not press a reset ( and even if you did) the motor is damaged and that is causing the circuit breaker to trip. You need to have the motor inspected to see if the damage is repairable or if you need a new motor. A local electric motor repair shop should be able to take care of that for you. The thermal overload has reset itself if after cooling down the motor is trying to start but trips the breaker.

To be certain it is the motor, disconnect the line leads and be sure they are insulated from ground and one another. Turn the breaker back on. It should stay closed which confirms it is the motor tripping it when connected.

If for some reason the breaker still trips, there is a problem with the electrical circuit feeding the pump.

Fridgeidaire clothes dryer


I will try this again i don't think i posted it properly.
On the power cord where it connectes to the dryer make sure the red and black wire goes to the outside screws (L1& L2) the white goes in the middle and the green goes to the dryer cabinet.
If you have the red or black going to the middle one it will trip the breaker.
