Sorry only just seen this, yes SN board shorted. If you go to eBay My TNPA5349 refurbished board can be found there my user name on ebay is robssupra . message me though there if you want, I would not recommend an ebay listed board repair service as there are no guarantees that the repairs will work and eBay will not give you any money back should this happen or if your board is lost in the post, this is why I sell the way I do Pluss you are up and running faster Regards John
