My 6PG Xtra's blue tube lit up very brightly then shut down with an Fd error code flashing.

I realise that the Fd error is related with the HV circuit, So I checked the following.

Checked the CRT faces and there are no cracks.

Led light on def board does not stay on.

Checked the HV board and the protect 1&2 buttons were in the out position.

I also tried re-seating all the boards.


When I disconnected the blue HV lead the projector functioned normally with the red and green projecting an image with no Fd error code.

I tried reducing the con/bright, but when I re-connected the blue HV lead, the blue tube lit up brightly again and then shut down with the dreaded Fd error.


Any ideas anyone. Please!

Anyone!

Either a bad CRT driver that's turning the blue CRT on full, or a shorted CRT. I've seen both. What's happening is that the high current draw is shutting the HV section down.

Thanks Curt.

Hopefully its the CRT driver and not the damn tube!
