I am looking for a price to replace the g board in a Sony KP-46WT520. Is this part available at all?

I haven't seen the G board available for sale for awhile now, but I do know there is someone on Ebay that repairs the G Boards for these sets at a cost of $40. You simply need to ship them the board and they will repair it and ship it back to you. The link to the repair service is below:
If you need further assistance let me know.
