Thank you for that info.
This is a time when the main control board has failed and needs to be replaced.
They do fail like this and they do not like to have the power cut after being live for a long time. The parts inside flex from the power being removed and then they crack and this is what can happen. Its the same for most electronic devices.
I will help you replace that part, if you are just a little handy and have a few basic hand tools you can do this, there is no soldering required, it all plugs into the control board simple;-)
The best place to get a new main control board is: http://www.ransomspares.co.uk/
Since there are so many different ones out there, I advise you to call them and let them pick the part for you so you get the correct one the first time for certain;-)
Also if you call, your order usually ships the same day you call. (not Sundays lol)
