I recently purchased a Beogram RX2 in near mint condition. 
Problem is that it’s only playing out of the right channel. 
I’ve checked the cartridge (MMC4) which looks to be in near mint condition also. I turned it upside down and ran the player. I then used a soft artist brush to gently brush the stylus and the sound was still out of the right channel only. I’ve checked the wires running through the tone arm and they all seem fine. 
I’ve checked the receiver (Beomaster 3000) and other things plugged into the PH sound fine on both channels. I’ve even plugged the RX2 into the tape input and can again only hear out of the right channel. 
It’s connected through a 5pin DIN to RCA to the receiver. I know that the PH has a 7pin DIN, but I’m under the impression that the extra 2 pins are purely for remote functionality. I haven’t connected the ground, but am holding it against the ground of one of the RCA’s when testing the turntable. Could the ground and the fact that I’m using a 5pin DIN rather than the 7pin be causing this issue?
I’m reading online that it could be the RCA cables (which look perfect) or the muting switch, but don’t know where to find the muting switch or even what it looks like. 
By the way, the turntable sounds stunning, even through one speaker. 
Any suggestions would be deeply appreciated. I really want to keep this turntable…
Cheers,

Check your wires with an Ohm meter, from the BG to the pins in the 5 pin din, then from there to the RCAs, A manual is available on site for silver and gold members

Hi there

It has nothing to do with 5 vs 7 pins in the DIN plug. As you mention - the extra pins (6 and 7) is only for remote functionality.

The problem can be in the cartridge. It is quite old now...
Or maybe in one of the RCA plugs? You mention, that you have checked the wires in the tonearm -but have you opened the RCA plugs to have a look? I know that on the Beograms fitted with DIN plugs, one or two wires sometimes can break off inside the plug.

The turntable is definitely worth keeping.

Steffen:

But if I checked the cartridge/install it upside down and it has the same issue, does that not mean the cartridge is reading and outputting both channels? Sorry if this sounds confusing. Just trying to be clear. Thanks again

Ok - not the cartridge, then. And you have tried simply switching the RCA left/right at the adapter cable?

Otherwise, check the wires as Søren suggested. Measure from the Beogram to the RCA plugs to rule that out. Then measure the adapter from RCA to DIN pins. (that reqires an Ohm-meter, of course...)

Don’t know what just happened.! Went to look at it this morning and suddenly it’s all working just fine. 

Do you know where I should connect the ground wire to a Beomaster 3000? There doesn’t seem to be a dedicated ground screw like the Beomaster 1900 I used to own. 
Thanks again for your time and great advice.
