Service manual says it has already selectable voltage transformer in it having selection of 120V, 220V and 240VAC. Anyway see page 9 of service manual ROTEL RX-855 Service Manual download, schematics, eeprom, repair info for electronics experts (elektrotanya.com)

Hello Ruben, so you do not open the CD holder tray of your Rotel, the problem is that the belt that transmits the rotation of the engine to the mechanism of the car, may be stretched and therefore the car does not open, this is the most common fault in this type of CD players You should replace it, if you can not do it, look for a specialized technical service I hope you can solve the problem Greetings Franco Dosil Hola Ruben, por lo que cuentas, no se abre la bandeja porta CD de tu Rotel, el problema es que la correa que trasmite el giro del motor al mecanismo del carro, puede estar estirada y por lo tanto el carro no se abre, esta es la falla mas habitual en este tipo de reproductores de CD Deber?s reemplazarla, si no puedes hacerlo, busca un servicio t?cnico especializado Espero puedas resolver el problema Saludos Franco Dosil https://elektrotanya.com/rotel_rcd-951-tm.pdf/download.html http://bwgroupsupport.com/downloads/manuals/rotel/RCD-951-OM.pdf

Several possibilities come to mind. First shorted connections to speaker wires. Faults in the power supply. Sometimes if the unit has not been working for a while the large capacitors in the power supply can dry up. An overload on a power transistors.

hi it sound to me that when you biamp and driving speaker and woofer , you are over loading the fuses , suggestions uprate the fuses till they stop blowing

Probably the EEPROM, the heart and brain of the appliance. I had the same issue with my AIWA, could not figure out the cause, took it in, tech told me EEPROM is blown. Not economical to repair.

Your changer has lost its mind and is doing crazy things.just like mine. Software issue not repairable.. Go shopping.

Try interchanging the speakers. If the right channel works, you have a problem with your speaker.

Check the rest of the power supply, for example the transformer if there is no power at all. If you are getting some indication of power, check the voltage regulator circuit.

Hi Awal. Interesting problem. Have you tried another pair of leads? What source are you using please, cd tuner etc? I noticed the the names for the five audio/video inputs can be customized by the user, Maybe there is a firmware issue? With the unit being surround sound Have you tried running in 2 chanels only?

I'm guessing you don't know for sure that it even needs fuses. They don't go out like they used to, as everything is controlled by a microprocessor(computer within your unit). I would suggest, that you, with the power plug pulled out, use an ohm meter to be sure that each fuse is shorted. If you need further assistance, or would like to inquire about a repair, please visit my website at audioserviceclinic.com. Thank you.

YOU ARE NOT RIGHT IT SHOULD GIVE AT LAEST A LOW VOLUME SOUND WITH A LOT OF DISTORSION AND A CRACKING NOISE IF DOES I GUESS THAT YOU HAD THIS AMP IN A PLACE WITH A LOT OF HUMIDITY AND YOU HAVEN'T WORK IT FOR SOME TIME IF I AM RIGHT PUT YOUR AMP IN THE SUN AND WORK IT FOR 10 MIN WITH A 5 MIN BREAK LET ME KNOW THE RESULTS

IF THE FUSE YOU ARE PLACING IS THE SAME TYPE AS THE ORIGINAL YOUR AMP HAS A PROBLEM WHAT YOU MUST DO IS TO SLIGHTY INCREASE FUSE BY 100 MAMPS PER TIME IF IT IS IN THE TRANSFORMER CIRCUIT YOU CAN INCRESE IT BY 2 AMP MAX IF IT IS IN THE MOSFETS CIRCUIT YOU CAN INCRESE IT BY A MAXIMUM OF 500MAMP LET ME KNOW THE RESULTS

I do not know anything about your brand or market, but I have had good success with replacement remotes at http://www.replacementremotes.com/ They have a very wide selection of mostly refurbished remotes. Originally supplied with RSX 1058 is this: http://www.replacementremotes.com/ROTEL/Buy-RR-1061-RR1061-Audio-Remote-Control.html

Turn off the other channel and listen only to the bad channel playing some music. Turn it up! If you hear any music the pre-amp is working and the power amp is faulty. If you don't, then the pre-amp is faulty. Because it's a stereo amp you have the good channel to compare with the bad. So you can do voltage tests, or "buzz" tests. Buzz Tests or where you apply a insulated tool to the circuits, a buzz will be heard. If it buzzers in the good channel it should in the bad. Ignore the power supply and don't short any parts out!

It's more likely to be a fuse that's gone. If so it could be caused by faulty device on the heat sink. The only device that converts power is a Transformer. You can test this by simply putting a Volt meter on it's terminals. They are not hard to fit, however they have to be replaced by the same thing or one approved by Rotel.

You have blowin a IC in it, Power amps are not suppose to be use for the purpose you were useing it for.You are dam lucky they didn,t go up in smoke.

Hello EricJust look at its connections. If the input connections have any loose connections at both ends, of the graound connection to both the devices are not proper, this kind of fault [intermittent sound and static noise] can occur. Reconnect all the connections and check the connection wires. OK.
