I used google on the issue and in the end had to re-install XP SP3 along with all the drivers. Fortunately for me I keep notes on that last XP machine on how to do that. The exact steps vary with each PC.

Replacement monitor Philips type 246V5LHAB. Current monitor is a Dell P991 (as we say - "on the blink") with a Radeon 256 MByte Hypermemory X600 graphics card. Have used the drivers from the CD supplied and from the Philips support site - I have used the Windows 7 drivers (all the implications for the drivers are that XP is supported) - all the the attempted installations fail with a message "A service installation section of the .inf is invalid" Any thoughts?
