I have ordered a power board for my 32AV520R form eBay. The seller said that it was removed from a similar TV and indicated the PK101V0981. After the purchase I looked at the ID of the board in my TV and it is PK101V10701. They look very similar, that's why i placed the order, but now I wonder whether I bought the wrong item from eBay. Does anybody know whether these two boards are interchangeable?
