No power to the receiver

I would suspect bad transformer. The board may not have a light because it is not receiving low voltage from transformer. With a multimeter you can test the transformer. But, since you likely have a short somewhere be sure to install a fuse right after the transformer or you will be burning up another transformer until you figure it out.

Fuses rarely go bad without a reason. If there was a power surge, then replacing the fuses might fix your unit but it is a very small chance. When replacing the fuses, make sure you get the correct fuses in the correct positions. The new fuses must have the same amperage and should have the same voltage or higher. Usually this information is stamped on the end caps on the fuse such as 1A 250V. If you replace the fuses and they blow out again, then there is a short in the unit somewhere that will need to be repaired. Usually the problem is shorted audio outputs or shorted rectifiers in the power supply.

The new fuses that you got have a higher rating than before - and they also blew. Tells you that you have a nasty short somewhere. I would check the power supply and/or output circuits.

Look in the circuit board area where the power cord mates with it for capacitors that have bulging tops (instead of the flat tops that are normal). If you see even one, you need to replace all the large capacitors othe power supply section (normally around 5 or 6).

Is the outlet live? Does something else plugged into the same outlet work?

Does the receiver have a master power switch on the back that may have been switched off by accident.

Some - not all receivers have user replaceable fuses. If you do not see a fuse holder on the receiver near where the power cord attaches then you may need to open the chassis to see if there are replaceable fuses on the power supply board inside. Follow where the power cord connects to the chassis. It will lead to a board with a transformer that changes high voltage to the low voltage that the receiver needs to operate.

IF there are user replaceable fuses inside they will be on the power supply board.

PLEASE make sure that the unit is unplugged and has been for some time as the transformers sometimes stores residual voltage that will harm you. Don't do this unless you know what you are doing inside the unit. I recommend novices just take it to the repair center.

Also - IF you replace with the wrong fuse type and rating you can cause further damage to your unit.

Good luck and be careful.

Fuses usually blow for a good reason - because something else is wrong.
A fuse may go once if it is just a bit old but if changing a fuse twice has not solved the problem then there is some sort of electrical fault that you need to trace. It could be

• a short circuit - maybe a crack in the insulation in the cable somewhere - most likely point is where the cable enters or exits the power supply and is subject to a lot of flexing or where it joins the coil windings inside the transformer.
• too much equipment connected to the power supply overloading it
• an open circuit or failed component causing- too low a resistance allowing too much current to flow
• a cable or component somewhere in the power supply that has too high a resistance for the current to flow causing a build up of heat at the weakest point - the fuse.

Unless the fault is something obvious like a broken wire it may just be a case of replacing the power supply

Hello, welcome to Fixya!

Your receiver is having a power fault because it is not switching on. The receiver might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

First, remove the unit's power cord from the wall, wait for about 30mins, then plug it back in. If it doesn't power on, plug it into another outlet, to make sure there electric current entering into the receiver.

If plugging into another power outlet doesn't power it on then it confirms that the receiver is having a power fault.

When electric current comes from the power outlet into the receiver, it goes straight into the power supply board which then circulates the current into the unit. So if the receiver doesn't power on, the first thing is to make sure there is power entering into the receiver.

So check the power cord, if it is a 3-pin plug, it must have a fuse in it. check the fuse if it is not blown. if fuse is intact, then power supply board should be checked.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter and continuity tester in order to read the components on the power board. Once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect and solve the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Good luck.

Try opening up the unit and look for any fuses that may have blown.(they are probably little glass types). Make sure you replace with the same type and rating. If the new fuse blows immediately, then there is a problem in the receiver that will need to be checked by a trained individual. Some possibilities are:Power supply/Amplifier output stage/most any defective circuit can cause a blown fuse

The odds are the circuit board that your putting the fuse in is shorted out. I'm guessing that it's a power supply board.

Disconnect every set of wires going to the board. Put the new fuse in. Plug in the power supply board. If the fuse pops, then the power supply board is the problem and has a short somewhere. Most replacement board can be found at a good price at Shopjimmy.com or Ebay.com. Just make sure the part number on the board matches up.

1. Make sure the AC outlet is good.
2. Make sure there is no damage to the AC line cord.

3. Look to see if there is a fuse at the rear of the unit. It's usually located inside a black circular housing with a screw off cap that says "fuse".

If not, unplug the unit and remove the outside cover. Look for a blown fuse on the motherboard or power supply. Replace it with the EXACT value of the original fuse. You can purchase a new fuse at Radio Shack or hardware store or auto parts store. Try powering up the unit again and see if it works now or whether the fuse blows again. If it blows again, the power supply may have been damaged.
Please let me know if I can be of further assistance to you.

Good luck!
