  • Ouverture Tuner Board Type

    I recently purchased an Ouverture. Everthing appears to work except the radio. The person I bought it from said that the radio suddenly stopped working. It will only tune from 76.0 to 89.0 Mhz. Hmmm that looks like freq for Japan. Type number on back of the unit is 2636 (EU) However, when placing the unit in test mode and query tuner type it displays 2639 (Japan) Not sure who or what to believe now. Is it possible to have an EU unit but with a tuner for Japan? Or can the tuner type be "lost"

  • Re: What Are You Working On Now

    Great job. I have a number of these Beolinks, all have dead pixels. I've disassembled one and removed the metal shield. However, in this case the issue appears to be in the crease of the ribbon cable ie. if the cable is bent or straightened, I can get pixels to show up or disappear. Applying pressure on where the cable is glued to the pcb or lcd makes no difference. Applying pressure to the bend in the cable does. Has anyone found a suitable replacement for the ribbon cable or some other way

    I would say It's the DIN connector and crossover of a CX50 speaker

  • Beocord 7000 Capstan Motor issue

    I have a Beocord 7000 where the capstan motor often fails to spin when pressing play. If you give the spindle a gentle flick, it will start to spin. The unit plays ok. Even with no drive belt in place the same fault occurs. Applying very light pressure to the motor spindle (with no belt attached) causes it to stall. A light flick is required to get it spinning again. I've measured voltage to motor at 12.2 volts. Anyone serviced one of these motors before or better to replace it?

  • Re: BM7000 issue after Lithium battery replacement

    I can confirm that point is indeed TP1 . BM indicates 88 when test mode is initiated. I've gone through the different test functions. Test 5 (RAM/ROM test) produces code 37. That is not in the list of codes in the service manual. Any idea on this one? I've erased the RAM. I still get status 37 on test 5 though.

    Here is a photo looking at the back of the CPU module. Lithium battery is located directly on the other side. Is TP1 in the upper left corner surrounded by the ground plane ( just above where the metal shield would cover?)

  • Re: BM7000 issue after Lithium battery replacement

    Thanks. That worked. However, I'm still wanting to get the BM into Testmode. I cannot identify from the drawing which pin to short as it only shows the area and not which pin to short. Here is the article that I'm looking at: http://archivedforum.beoworld.org/forums/p/31732/256614.aspx#256614

  • Re: BM7000 issue after Lithium battery replacement

    With a scope on CPU pin 12, IR input, I can see data when pressing a key on the remote. So I'm hoping that your suggestion of setting the option is on the right track. However, I'm having trouble identifying TP1. The circuit layout of the BM7000 CPU module looks a little different to the BM6500. I've tried with the BM on radio, pressing sound 1 store, but no response. My circuit diagram shows Test is on pin 7 of IC3 which is a 4021. I don't see this in the CPU module that I have.

  • BM7000 issue after Lithium battery replacement

    I have a Beomaster 7000 that would not keep correct time after the power was disconnected. I removed the CPU module and discovered that the Lithium battery (CR2450) was leaking. After having replaced the battery with one of the same type the Beomaster now will not respond to any commands from the remote. The Timer Off light is on and if the Mute/Power button on the right is pressed, the display indicates 7. Successive presses changes the number from 7 to11 to 22 and back to 7 again. Not sure if these

  • Beogram CD50 Display segments not working

    I have recently restored a Beogram CD50 to working condition again. However, there is one issue left that I've not come up against before and am not sure on how to go about solving. A couple of the LED segments are not working. I've removed the display board and red number cover. The surface mount LEDS look like something I've seen out of the Beomaster 8000. Anyone repaired (replacement surface mount LEDs?) one of these before?
