FBT's fail all the time due to the HV stress. etc. Even if the freq's did
get scrambled, it wont do anything much more than an out of sync pix
(internal defaults that can't sync up).
Besides, monitors often have a discrete H deflection driver to accomodate
the various operating frequencies and the FBT runs at it's own multiple.
If you want to check the settings beforehand, restart the computer in "safe
mode" by hitting "F8" duing reboot. This will set the monitor to a very low
resolution mode. Then check the display settings.

was way off. After much problems trying to change the display settings, the
drivers were deleted and re-installed and the computer works. Is it possible
the drivers got corrupted at turn on and zapped the flyback? I would think
it was more likly a spike zapped the drivers. Please tell me in what order
this thing went down? It does seem strange that both went out at the same
time with nothing related. It is probably the old saying "which came
first...the chicken or the egg".
