Oh my, the infamous D7 32" flyback. I thought all those would have failed
by now.

Philips had a serious problem with the flyback failing on these. Lots of
parts would fail all over the place, including tons of surface mount ones.
You really just need to troubleshoot all the way back. I have even seen
corrupted eeproms from the flyback fail on this one so any failure is
possible.

You did replace the ENTIRE lot of parts that was included on the sheet with
the upgraded flyback from Philips as a starting point????
