The MX5500/MX6000 series uses a single (presumably digital) pin to transmit and receive stand data, which connects to the AV link bus inside te television set. (Service manual, p. 17). The MX8000 uses an analog system on the 5-pin DIN connector, with a feedback potentiometer to determine the stand position and two active low outputs to control the stand

[quote user="Die_Bogener"] The main transformer i dont remember... maybe some wire bridges or a new transformer. [/quote] I'd suspect the main transformer to have a set of windings for either 110/115V or 220/230V, the latter of course using twice the windings of the former. On a lot of A/V devices (not neccessarily B&O), the 110V live

Line inputs are high-impedance (47kOhms) so splitting the signal and feeding the TV and receiver simultaneously is absolutely no problem. You just need a couple of RCA "Y" adapters to connect your television and Beomaster at the same time. Merging two signals to supply a single input is a different issue.

[quote user="tournedos"]The "Ye Olde Format", as I now call it , used by BG4004 and I guess 2404, has really nothing in common with Datalink, new or old. The only Beomaster using that format is 2400-2 as far as I understand. The message only contains a couple of bits, and as these Beograms don't even have a microcontroller, is

[quote user="tournedos"] Google for "datalink.zip". There used to be a broken link for it in Beotech - might actually be on site somewhere nowadays. The IR remotes use the exactly same data format (but obviously L level on bus = 455 kHz carrier on). EDIT: Yes it's on site - rather confusingly as the MCL2 technical service manual

Hi all, Since a few years I'm in possession of a Beomaster 2000 receiver and accompanying Beocord cassette deck. The unit was originally owned by my parents and was put aside as being defective due to a lightning strike several years ago, and I got the whole set for free. (Unfortunately, the matching Beogram was trashed because of a wasted pickup

Tiny update: My first hunch was correct. Getting the service manual online, and after disconnecting the AF outputs on the receiver board (second flat cable on the number 1 PCB) and the unit gave brilliant silence on all of the inputs. The AF lines must have been leaking HF noise as well and messing up the entire AF signal path. The external inputs work

Our Beomaster 2000 suffered a lightning stike a while back. The unit powers up and all of the touch panel functions work properly, as well as the power amplifier. But... it suffers from a lot of noise on the speaker outputs. My guess is that the lightning strike may have blown some capacitors which filter noise from the tuner stage to the power circuits
