Hi john
yes I have got away with just changing the chip on several occasions, you usually find the fets measure short when the chip is in circuit but are fine once the faulty ic is removed, be wary of boards that don’t have a blown ic as the fault where the pic appears for a second can be caused by the lamps them self’s, got stuck with a couple of inverters due to this  on similar sets, but suppose will use them eventually.

Hi daz
Thanks for the info- will need to consider that possibility if another one comes in with no signs of distress on the inverter boards. The one I repaired with no apparent damage had the same symptom as maff99s set - half a picture, but it didn`t trip off.
Cheers
John.
