I can help you solve this problem. However you must describe to me which fuse you have replaced. Is it the fuse on the power line or is it a fuse in the speaker line (which I highly doubt). usually this type of amplifier uses two technologies. One is transistors the second is integrated chips. This is in regard to the output stages. I assumed you speaker cables shorted each other while the volume was set at a high level with music playing. Anyway if you are willing I am able to help.

This is a very common problem with denon receivers of the 2001-2-3 vintage. On almost every one, there are 4 little "surge" resistors in the power supply. These werent quite robust enough from the factory and one day would just burn open for no reason. Well, actually there is a reason, the "surge" that happens every time you power the unit up eventually weakens the resistors and then they pop. You need to take this to a denon service shop as I GUARANTEE they have seen this before. They need to check resistors in the picture, locarde above the **** rectangular connector. Resistors numbers R141, 142, 148, 149: 75f69d7.jpg These resistors when measured, should be less than 10 ohms each. If they are more, then they are blown. If they are blown, then have the shop check the channels for blown output transistors. If the outputs are OK, then these resistors should be replaced with 1 ohm 1/2 watt metal -film flameproof resistors. You might need to be prepared for a large bill, because the entire unit must come apart to replace the resistors, however, just checking them takes only about 10 minutes... Good luck and don't try this at home. Rob

Plugged into wrong voltage.


Hi there, it's Jack at Dyson.

Each Dyson machine is manufactured for use in the country it's sold in, and will be tested to meet all relevant legislation for that country. We strongly advise against importing a Dyson from abroad or attempting to convert it - the machine may not work properly, and any damage caused wouldn't be covered under warranty. Unfortunately plugging a 110v machine into a 220v current is likely to have caused significant damage to the motor and any control electronics within your machine.

Accidental damage caused by connecting your machine to an incorrect voltage isn't covered under the Dyson warranty, and if you've imported your machine from abroad we may not have the parts, facilities or training to support this model locally.

However we would be happy to discuss your options for repair. Just give the Dyson Customer Helpline a call on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU) so we can take some further details.

We'll look forward to speaking with you.

I accidentally plugged in my pulmoneb in a 220v outlet


plugging a 110v device into a 220v outlet is not likely, as the plugs are a different configuration. In the event that you somehow managed to do that, your device is probably fried, as that would be to much voltage. Hate to say it; but you are probably gonna need a new one

My son accidentally plug a 110v bose 3-2-1 to a 220v outlet. What do you think is the damage? Do we still need to send it to a service center?


If you are lucky you would have lost the fuse on the sub woofer module which powers the whole unit. If not, yes you will need a qualified technician to look into the matter because its not a small offense to plug a 110 device into 220v.

A friend from US gave me hp netbook-1103135- is it 110 or 220v please advise thanks


It most likely has a 110V plug on the power supply; however, all you have to do is buy the appropriate 220v cable for the power supply for your country, and it should work fine on 220V.
External power supplies are designed to use either 110v or 220v -- all you have to do is change the cable or use an adapter and you're good to go.

My subwoofer IC got burned because i accidentally plug it to a 220v power supply, mine is only 110v i want to know the IC# subwoofer.


Most likely what got burnt is the bridge rectifier in the power supply section of the electronic circuit. This usually takes the shape of either a single 4-legged IC, or a group of 4 rectifying diodes connected in a bridge configuration. If you disassemble the unit to which the power cord is attached & trace the circuit starting from the terminals of the power chord, you can easily identify it. You will need to replace the 4-legged IC or the 4 rectifying diodes.
You will also need to replace the fuse, since it is usually likely that it gets burnt if the unit is attached to 220V instead of 110V.

There should be a switch that you could set to the various voltages. Normally a round switch in one of the corners on the rear panel that you can turn with a flat screwdriver

Help required for dumbo on Amps Denon AVR 2808CI


Your unit was probably damaged in shipping. Denon is a nice unit! Do you hear any clicks when you hit the power button??? You should hear two relay clicks. You should hear the power relay click at power on and 3 to 5 seconds later you should hear the speaker protection relay click if your audio amp section is ok. If you hear both relays click then your display circuit is at fault. Open the unit and look for breaks on the front pcb (behind the display) and on the main board in the power section ( where the fuses are ).
Good Luck!

WA71N2 plugged to 220V should be 110V


The Fuse for these model is 110V - 250V, so definitely the machine will still light up for a moment then black out. So if you accidentally plugged it to 220V (if it is 110V) you have to change the whole PCB. Electric current are distributed by PCB which only handles 110V.

I suggest when you change the PCB try to change also the Fuse to 110V only so that next time if by accident it was plugged to 220V you just have to change the Fuse not the PCB.

Accidentally plugged the 110V to a 220V


Hi,
you,ll have blown the PSU.
there maybe an internal fuse, located in the PSU. but if smoke was bellowing out, i,d say it went straight past the fuse.
New PSUs the best bet.
