My Cambridge 840A V2 won't power up. It is completely dead. is there an internal fuse that I can replace?

A video that might help on Minx Go and a link to Cambridge Audio Support.

Hi Veeranjaneyulu, control the output transistors, they are Darlington type, exciters and preexciters
I send you the service manual link, version 2 (V2)
Greetings Franco Dosil

Hola Veeranjaneyulu, controla los transistores de salida, son del tipo Darlington, los excitadores y preexcitadores
Te envio el link del manual de servicio, de la version 2 (V2)

CLIPPING occurs when the level of sound is way too high.
Try changing the speaker-wires -- you may have a short-circuit someplace in the wires that is causing "feedback".

The volume control is a resistor ladder controlled by software. If powering off the unit for an hour doesn't fix it, I would imagine that one of the "steps" has a problem. Contact your dealer or visit http://support.cambridgeaudio.com/.

Hi,
If your unit has no led light lit on the front panel, this is an indication that the power supply board is not working(dead).

First thing to check is the basic, I'm assuming that your outlet is live. Check the continuity of the power cord using the multimeter. Sometimes it has an internal broken wire due to frequent pulling and bending. If the power cord is good, open the top cover of the unit and check the internal fuse. Sometimes due to voltage surge and aging, fuse fail. If this is the case, replacing with same current(ampere) ratings will cure the problem.

Let me know if the fuse is intact or blow again after the replacement to determine the next steps.

Years ago the volume and balance on amps were on seperate circuits. But these days they are on one. It sounds like this problem is all down to an IC in the pre-amp stage. If you trace the connection from the volume control to the PC board you will find this chip. If you come accross more than one, put the code numbers into Google and see what they do. If you see one the at deals with volume and balance, you have got the culprit!

Did you take the time to fill out the Warrenty Card? It's VERY important that you do when you buy ANYTHING, especially electronics. Call the store where you bought it. Ask them if they can track it (the sale) If it can be fixed under warranty, be prepared to have to ship it back to the manufacturer.

Get a 2.5 mm stereo cable to dual RCA ( phono plugs)
Radio shack or Walmart will have them.
Connect it to the aux or CD input in the rear of the amp.

get an Ohmmeter, take a reading on each speaker line one at a time, on both A & B speaker lines. You should get a reading of 8+/- ohms. The speaker switch with the 6 spks will probably read almost 0 ohms when all 6 are running. That is what your amp is not liking. Try running it with one set of speakers on the switch,with the Tannoys on ch A on your amp and the switch on B. add one pair of the 6 at a time and you'll see that it won't like all 6 at once. 2, maybe 4, at a time is probably what you'll find to work.
Good Luck.

best connection from pre-out to aux in.
