Yes. The RROD is a serious hardware failure. It is the equivalent of an engine failure in a vehicle, and although there are many "repair kits" available on the internet, none of them work for very long. In order to properly fix an RROD, you need professional equipment, like an infra-red thermometer, hot-air rework station, X-ray machine, etc.
