Dead PC flat panels, mainly HP

[photonic]

Hi all.
I have a few of these, mainly 17" but some 19" panels.
Any ideas where I might obtain replacement BT31xx series drive chips. as these seem to be the problem.

tested all the inverter transformers and they seem fine, transistors are OK.

some of them are the 3105 not 3105A, tried swapping but no go.
Already did the capacitor replacement..

Any ideas please?
