Hi Bruce and thanks, suspected might be the case, my diagrams were horribly difficult to read.
Just for fun, tried read Eeprom on a CV109H MB where set was doing odd things. Took maybe 40 attempts with the clip to get a reading - seemed OK compared with a held bin, but then found set was stuck in S/by.
Later discovered I'd knocked off L11(SMD) attempting read the chip, guess any SMD chip inductor might do, as shematics aren't to be had.
All fun - Chris.
Later - Replaced L11 with something off another board, found things the same, so changed Eeprom for a similar model - All OK apart from solarisation - Murphy C3298F from Cello C3298F - same panels and screen - So it goes.
