Your set uses 3 STK391-020 and are on the heat sink to the side. Do not confuse these with the more common STK392 series chips. Buy them from a reputable supplier such as one that I recommended above. There are other problems beyond the chips in these sets sometimes. Often one of the pico fuses blows when the chips fail.
