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!

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.
