Hi: My BG 4002 AC motor has developed a "knocking" sound as it rotates. I can make it go away by holding/lifting the spindle as it turns but eventually it comes back. Does anyone know what's going on? Perhaps it needs lubrication after all these years? Derek

Gerhard: This is a beautiful picture. Your photography skills clearly exceed mine! Perhaps you can take a picture of one of your faulty leds? You are absolutley correct about the molded SMT Leds being more rugged. I don't think the LEDs actually "burn out." It's that wire that you show that becomes disconnected. One less invasive solution

Hi Martin: The belt is quite loose and actually chould be changed because it slips a bit so it is not pulling the platter over. The front most leaf spring won't adjust enough to compensate. I can get it to lift but it also lifts the part in the front transport lock to the point where it touches the roof of the collar. The question the begs, well

Hi: Does anyone have an idea how to "center" the platter on the BG4002 so that the platter is equidistant from edges of the deck plate? Also I haven't been able to get the platter completely level with the deck plate in that it is on a bit of an incline. The edge of the platter is nearly flush towards the back but dips a bit up front.

Hi Laurence: I think you have to be more "creative" than simple capacitor replacement; the task requires much greater skill and dexterity. First you must disassemble the LED modules which requires desoldering multi pin devices! The B&O pcbs are not very high quality and so you must be very careful because you can damage the traces!

Well John... there are no Guiness book of world records here as far as I'm concerned, only sharing information that may help others keep these wonderful products around and functioning. Member "Dillen" (Martin) has also come up with his proprietary technique (before I attempted my repair) to fix these displays. He reported success and

Hi Laurence: Yes the problem with this solution is that it requires placing at least a pair of LEDs because of the strobing. 2 LEDs share one current dropping resistor. Also to match old LED with new requires selection of current value of current dropping LED so that the new segment will match closely with the old. Thus for practical purposes it makes

Hi Gerhard: Since it is unlikely that ALL segements would go bad on your volume display, I would suggest that you look at the decoder IC to make sure that it is not dead. Or simply measure the voltage across each segement to check for power. Let me know how you make out! Oh I also used a higher value resistor on the decimal segement of the volume display

If you swap the entire composite frame, please be aware that the molded catridge compartment is different between BG 8002 and BG 8000. BG 8000 is molded for MMC 20 series BG 8002 is molded for MMC 1 series Derek

BM 8000 Display Fully Restored. A few things to note here. The top row of the display has been completely rebuilt. The "Balance" segment did not have any bad segments and so I elected not to swap out the LEDs. The true color of the original display is the ">" arrow segment of the Balance display. The digit of the Balance display
