    Solved the problem. Previous owner had changed the LiIon battery underneath, but had failed to clean the pcb for the acid leftovers - see the rust on the cover, must have some leak ! Replaced (invisible) broken track with a piece of wire - and everything works perfectly again :-)

    Just tested the blank IR diodes: no output

  • Beolink 7000 repair

    Hello oracles (!) Have been refurbishing quite a few Beolink 7000's with great success until now. Got a unit in mint visual condition. Changed the batteries and button battery underneath the pcb. Changed all the capacitors too. Desoldered the chip next to the two SMD-capacitors but no sign of any leaking capacitors. PCB looks clean and neat But the damn thing still doesn't work! Display, touch, programming etc. all works, but it simply will not communicate with the Beomaster 7000 - not even

  • Re: Beolab Penta Mk I with Mk II display

    Finally problem solved: Pin6 on the display (audio/video signal) - When audio signal is fed via the RCA plug, this pin is grounded - must be high to turn on display. Removed pin6 on the plug resolved my problems :-) Has anyone modified the resistors/LDR resistor on the Mk II display - output is pretty low and hard to see when the acrylic covers are fitted.

    Well... not quite true! This one is really bugging me..... Scenario: Beolab Penta Mk I with refurbished Penta Mk II displays. Display is connected via the 2 pins on the DIN plug. Audio is connected via the RCA plug. Source is BeoMaster 7000 using the Powerlink output. (Please recall the the Penta Mk I does not have the Powerlink plug - only DIN, RCA and speaker terminals) No display when the 2 parts are connected. When audio RCA is pulled out, the display works as it should! I am beginning to suspect

    Problem solved: Display data input ground wire was missing. Now all is working fine :-)

    Yup, tried that switch too - no difference. Is there a way to test the display if it works at all?

    That switch is included on the pcb (goes to the audio/video input on IC2). I believe I have tried to switch that one too.....
