I have a samsung 64 inch plasma. Problem with power board. One thermister blew, but beside it is, what I believe, a fusible resistor(it has an orange stripe at one end and a green stripe on the other end. On the board there are 2 of them identified on the board with the following number: RA801S and RA802S. I am more concerned with the RA801S as that is the one that has a broken lead wire In order to provide a replacement I need the schematic for this board unless someone has a data sheet for these 2 components or a schematic for the board. A schematic for any of the BN44 boards shown in the attachments would be acceptable as I believe those 2 components are on all those boards Any help would be appreciated. As an FYI, I spoke to a tv repair shop and they indicated there are problems with these tv's stemming from the panel which in turn messes with the power board. Picture of the power board is attached which also shows other BN44 boards that, I believe, are considered, compatible. The original board with the TV blew and when I could not find anything that stood out that was wrong with the board and after doing some testing on some components I purchased another board from Samsung at a cost in excess of $250 it lasted for only 2 months before it blew. Purchasing another board is not an option considering the cost and the length of time that they last, so my intent is to do anything I can to repair the existing one and if all fails I will just junk it. Parts are very inexpensive through Mouser.com vs purchasing a new or refurbished board, but this also provides me with a learning experience. I will, if keep this post updated as to my sucdesses and/or failures(hopefully no failures). The most annoying thing is in trying to do any DIY repairs is why schematics are such a proprietary held secret and not readily available. I remember purchasing electronics in the past(a good number of years ago) a schematic was always provided with your purchase.
