I have found:

'456 005-15 REV:8F
MFG:732 B0653

5102820015P
E13-7810M '

and

'WK.734'

on the 'heatsink' around the flyback transformer.
and

'452051-15 REV:4G
MFG:732 B0653'

on the circtuit board that plugs into the CRT.

maybe this can help somehow.
What is the process of replacing the flyback transformer ??

- thanks in advance,
