[quote user="Step1"] Now switch the unit on and allow the arm to move to the start and drop (although remember it won't actually drop without a cartridge!) - move the arm manually with a push from your finger to the left, as if advancing along the record - at this point the carriage assembly should move with your finger - I then move my

Hey, You (deliberately?) forgot to tell us what deck you use! Here you know you won't be laughed at by $500 cable guys!!

Hi, On my Beogram the arm was stuck at the main bearing of the lowering mechanism. See here: http://forum.beoworld.org/forums/t/37107.aspx It is a bit tricky but it could be your final problem! Does the arm pop up swiftly when you press STOP or does it take some time? Make sure the carriage moves when you push the arm to the left by hand! (as a reference

[quote user="chartz"] It should light up actually, as soon as you press "START"! It should show the B&o logo in red too... Gently slide the black extremity of this detector arm out of the arm and test the bulb... [/quote] ... with an ohmmeter of course!

Again yes, but this is missing the point, since we were wondering about the detector lamp, and the shutter lamp in the first place, weren't we?(sorry if I'm being thick here!) Jfrancis told us he did have this LED fitted and that it was working anyway! I doubt the LEDs in the detector arm and the shutter would work at all! Oh well.

Yes Menahem, but we were discussing about the detector arm and shutter lamps. I saw somewhere (not in one of your posts) that it was possible to fit LED's in those places, but I couldn't achieve normal behaviour. So if you have a reliable solution it will be useful to everybody here. I already have the SM for my 4002 and yes it shows the IR

Dear Menahem, Yes I know, my 4002 has a LED but it is infrared, not white light. However, I would be interested to have a diagram of a 4002 or 4004 with a LED in the shutter or in the detector arm. If such mods are possible, please let us know how B&O did them. On later Beograms (6006, 8000, 8002) there aren't any LED's to be found. Is the

If the SO switch works then there should be no power supply at all because it grounds the command of the first power transistor. Are you positive that the switch operates?

Hi, There is no link between the two bulbs. But as I told you, on PCB 4, there is a leaf switch for the shutter bulb which turns it off when the arm is in its resting position. Either the switch is dirty or more probably it is misaligned. You normally clearly hear it when it triggers.

[quote user="jfrancis"] One other thing of note is that the end of the sensor arm does not light up as the arm travels which may mean nothing but I am mentioning it anyway. [/quote] Oh that's good news! It should light up actually, as soon as you press "START"! It should show the B&o logo in red too... Gently slide the black
