They have no intention (the engineers) of making them hold up. We should be grateful.

If they look melted, from too much heat, a new one will drop the temperature slightly, but no matter what you do,...they will still run too hot. I think it's a just a poorly engineered design. They should have put larger heatsinks on them to start with. IMHO. LLW LeRoy Westlund Westlund TV & Electronics 97 North Main "Where there's a will,...
