Question about Televison & Video

1 Answer

I have a samsung ht-x40 dvd home theater system that powers up briefly showing "hello" display, then the function it's on. Immediatly after that the display comes up saying "protection" and the unit immediatly powers down. I have pulled the electrical plug and replaced it into a different outlet, and even removed all the cable from the back and it continues to do this. Any help would be greatly appreicated! THANK YOU!

Check the components near the fan in the back to see if any caps are fried (looks like it exploded)causing the protection circuit to come on if this is fine then check the fan to see if it if freely moving.

I got ahtx-40 and after running for a while it displays protection and the power goes off. helppppppp!!!!!


I have the same HT-X40 home theater as you do, and my problem seems similar to yours. It'srelated to overheating. First check the fan and air flow from it. Ifit's OK, the problem can be inside the unit. In my case one of theoutput filter capacitors got broken - it had a crack on its body.Replacement of the capacitor fixed the shutdown on protection.
Anotherquestion is what damaged the cap. Preliminary I consider placement ofthe capacitors as a possible problem - they are too close to the outputinductors which can get relatively hot even at normal workingcondition.
