afer changed out 3 burned tubes with 3 new ones, of my G90 RGBHV input was lost . i did everything complying the service manual with te remote, but showed " NO RGBHV INPUT" on the screen without exception, but HDMI V3 input still worked perfectly.
before ,both RGBHV and HDMI V3 worked , after,(i had done nothing to any electronic board, only restored system to factory setting with the new tubes installed ), only HDMI V3 input worked, RGBHV input was dead, any idea?
any helpful information would be greatly appreciated.

Have you checked all the connectors and reseated the board? Hard to imagine how you could damage the board by just replacing the tubes.

Do you mean that you cannot select the BNC input A, or that you can select input A and have no picture?
Try the "sys set" button on the remote. I wonder if your G90 thinks it's on a switcher...
