We’re looking in to getting solar on our house and I wondered if anyone had used anyone good in or around Epsom?

Edit: I have found someone via my facebook post who is able to do sone diagnostics for me and point me in the right direction.

As the title asks
(I am local to Spelthorne/Elmbridge but willing to travel anywhere in Surrey to drop it off)
Bought one at a car boot last week and it would appear that it is hard bricked. This was unexpected as I had been told it was in working condition (I trust people too easily and have now learned my lesson). The repair service CEX use are unable to help.
There is a place I can post it into as a backup option but I’d rather explore local options first.

I am not confident enough in making myself a bayron sweeper nor fiddling with the internals of batteries to try and do it myself, nor can I find an already made unbricking kit online. Have checked everything else I can with the PSP and all signs point to it being hard bricked and I’d say I’m 90% confident in that being the issue.
The PSP is a PSP1000 so an original.
