Hi mykeie
This type of problem is usually caused by faulty electrolytic capacitors on the power board. The faulty ones usually have domed or split tops.

mykeie:
many thanks for the reply. what is the best way to repair this problem with the electrolytic capacitors on the power board and is it a simple fix?
thanks

Hi mykeie

The suspect capacitors are in one corner of the board and are usually 1000Mf 10Volt types. Remove the circuit board and de-solder them. Replace them with (solder in) 1000Mf 35Volt types observing correct polarity. Re-assemble and hopefully set should work.
Good Luck

John.
