If you have read the thread you will see it could be the main board however
we can look at it with you.
Welcome to the forum-
We can help a lot more if you please post good clear pictures of the whole chassis, and then pictures of each board, front and back and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.

Please do not post inline and offsite as they slow down the loading of pages.

It will be useful if you can say what the supposed fault was and a bit about yourself - skills tools etc.


Please update your profile with country and mains voltage.

We need to have pictures of YOUR boards - it is no good looking at problems on other boards.
