TV dead after lightning. Line fuse OK. Diode (board number) 6560
shorted. That's all I have found so far.

Replaced the diode with ECG598. Pushed the power button and heard the
click of death. Replacement diode again shorted.

6560 is the main supply (140V) rectifier. Check 7460 HOT and
other stuff on the main supply. Schematic is available only
on the Philips service CD, unless you can sweet-talk someone
into sending it to their printer.
