Anthony Pr :

Hello Welcome

Do you have any soldering skills at all?
This problem is usually failure of bad electrolytic capacitors on the powerboard

Let me know

Anthony

Customer:

unfortunately not. Should we get someone to come repair it then?

Anthony Pr :

Hello again

Anthony Pr :

OK this is an australian set so I cant give you another option that is to replace the whole powerboard as I dont know of any suppliers in oz

What you could do is have a look at the part number on the powerboard and google it, the powerboard will be easy to find as it has the powercord going to it, on that board with a sticky label should be a number that may start BP**-*****

Anthony Pr :

The powerboard is very easy to replace a few plugs and sockets and screws holding it to the chassis

Anthony Pr :

If you dont want to do this i'm afraid a technician is your only option here

Anthony Pr :

Hope this helps
