Hello everyone.
All projectors have continuity between base and ground DC; if USB sound card is connected.
I have done some test ... the problem of the line that is seen between the circles, is due to the red diode driver (I will have to replace it). This problem is identified.
But smaller on the center ... I can not identify the problem.
There are some instants that the image appears correct (only a moment), I think it is not galvos adjustment (I have not touched any adjustment potentiometer!).
I have connected ILDA 25 to projector base (Norty 303); problem is the same (smaller on the center). When connecting DC ground to base, some noise appears in the speakers.
Smaller on the image center... I'm worried it's a problem in galvos. ?
Please if you know any solution, let me know.
Thank you.
Thank you very much for your help and excuse my expression, I use a translator because I do not know their language. Sorry!
Best regards.
