Check your OPTION BYTE:
Whenever you are called in to service a Tulip chassis (61/65/66 series) always
check the Option Byte settings in the service menu. It's a good idea to get into the
habit of verifying that the Option Bytes are correct even before you remove the back
cover (it might be possible to view the service menu even if there is no video or
