Hi Hak,
At the end I sent the wrong PJ to the address given by Linna and now received the apparently ordered one. This one came with remote control in the box and has microphone built in, but does not work.
I mean the 1st wrong PJ (RG) started autoshow after power was on and key switch turned 90°. In this one the key switch can be turned several times 360° in any direction and looks not fixed to the body at all. Fan is making noise and I would say that I can hear the sound of mirror motors but it seems that no lasers are inside (they do not turn on).
As the 1st one this PJ does not have serial number, nor any inscription on panels stating that it is LK-3D.
Have you really managed to get working things from this supplier in the past?
Edit: OK the reason for lasers not switching on was Interlock connector also had to be in place, so 2 safety features in this device!
Now I see all 3 RGB colours and rotating 3D figures projected.
Can anyone advise me what do I have to buy to check DMX feature? Is it a kind of hardware interface to computer with DMX software in a bundle (like Soundblaster with its software was for HiFi)?
And the Key switch had no washer behind - I opened back panel and tightened it . Now it is OK. Anyway I am going to dismantle it one day...
