The original resistor appears as shown, and I have observed that it consistently burns R7914 and cracks IC7905. Additionally, I have replaced the 3x power boards over the past four years.

weiyann83 could be that as JWx suggested the MOSFET is stuck ON. One thing you could do (a little nuts) 2.2Ω 5W 5% fusible resistor. and mount it off the board maybe even bend a small aluminum into a U-shape and clamp it to the resistor. personly you could use a hose clamp BYW heat compound is used as well. You realize that this is OVERKILL ~~ Cris
