Hello,

I want install a led lamp to my Panasonic pt-ax200. I need to bypass the lamp check.

I found in the service manual the circuit for what Panasonic calls "photo isolators'". See the attachment.

So how can i fool it?

 

What does it say in the service manual for lamp detection, is it monitoring current or illumination?

 

It used to be that people were short circuiting one of three the optocouplers in these led projectors to fool them think that lamp was on

Maybe these attachments will help

 

The service manual can be found here:
