Hi @roel1 ,
I can’t find a service manual or schematic for the power board online but it seems as though there may be some known issues with it as there is a repair kit available for the board.
If changing this many (or type) of components doesn’t appeal, search online for a replacement power board. Just search for BN44-00625C L55X1QV_DSM to get results for suppliers that suit you.
Given the number of components in the repair kit it looks like a section of the board has been redesigned (components may have different specifications, I don’t know), unless they are just replacing all the components that may lead to the failure of QP801C or QP802CS, as all the components have board designations in the same range which usually indicates the same general area on a board

The ~100 and ~200V outputs towards the backlight work.
The 13V output delivers 9,7V
Any ideas?
Anybody tried fixing the power board themselves?

It looks like this is a technical issue. I even don't know much about it.
