It could be a faulty eeprom.  Try checking the clk/data. Sounds like a fault I had a few months ago.

All the best

Hi Steph,
Thanks for your input,

On further investigation Ive found that the set will start up ok sometimes, maybe temp related? (waiting for new can of freezer to turn up)
and it does seem to be a data line fault as I get a very short burst of data at power on then nothing when it is in fault condition and steady clean data pulses when the set decides to work,

Is the eprom is standard & available?

Jon

Not sure where you can get one from. I might have a spare one, let me know the number of the memory ic and i'll see what I can do
