Question about Televison & Video
Possible that when the MOSFET'S were changed the Switch mode oscillations were not proper and so the drivers were driven too much to fail.
It will be best to replace the whole power supply if the mosfets are heating up more than required.
Also replace all the electrolytics and check the SM transformer after the mosfets are replaced and before switch on. Check also the load on the output , if there is any short or leakage on the drive output .
