Problem with Panasonic PT-105/ 106


Standard Member
I habe a Panasonic PT-106.
The problem is that the Tubes don't start. So I don't see anything. I guess that there is some problem with the power.
When I switch it on everything looks fine - except that there is no picture (test pattern)
The Fan is going the red LED on the D and E-Board is on and the end of the Tubes are glowing.

I know that this model is similar to the PT-105 so I already downloaded the Techguide and Servicemanual from
Panasonic 1083/1085 Tips and Manuals

I checked the parts from the service manual on page 19 but this seems ok.
How it happend:
The crt was on and working fine. I left the room for a moment and when i came back the tubes were off...

I'm not so familar with crt Projectors so I hope sombody can help me to fix this great pice of technic.

Many thanks in advance
