philips 32pt66 turned into a monitor only
 

I have this 32pt66 philips that has no audio and no tuner functions. No
channel indicator onscreen. Video input is the only thing that works. I
can get the customer menu and adjust the video but can't do anything
with the audio. Closed caption works.

Is there a service menu on this model? I read somewhere that philips
use onboard jumpers?
I just found the code for magnovox to get into service menu but don't
know if that will work on this model, the date code 062595 menu, is
magnovox service menu code.

Reminds me of the sony's that you can change the ID code and get them
to operate like monitors instead of tv's.
