Samsung HT-TX72 Home theater system shutting off

After a few minutes of viewing it flashes "protection" and then shuts off. I've had the system for over a year and it never did it. i moved recently and since then it does it every few minutes.

Protection is caused by a short , a bad voltage, or a component that has blown.

Unplug power cable, if you still get protection, then the unit is faulty.

    If the system goes on protection when yopu move it then it is likely a bad wiring (broken solder joint on board usually) or a short iside the unit.

    When you get protection, that means that there is an internal fault, in this case the manual suggests to send the unit for repair.

SOURCE: Samsung home theater

After having my unit for a year, it now reads this PROTECTION message. I tried to restore factory settings also before calling Samsung & they said something wrong with the cooling fan. Haven't tore into it yet, but does the units come with a fuse that might be blown. I'm tring to find free schematics on the net but hard to track down. If you just got yours, take it back to the store & get a new one!

My samsung ht-tx75 home theater system shuts off for no reason, any ideas of what it could be?


It sounds like you have either a thermal problem , or an electronic component fault in the power amp section. If the protection circuit is being activated, which disconnects the speakers so you have no sound, this is like to be the problem. Unless you are a trained technician, you should take it to a repair center. If the repair estimate is larger than you are prepared to pay (unlikely, unless it is a snobby shop) you have to decide whether to replace it with a new or used one.

I have a samsung ht-tx75 and it keeps shutting down every 10 minutes saying protection.the fan is working


Protection is very likely caused by an over heat condition, even with the fan working if the receiver is in a very enclosed place that warms up and is not ventilated it will cause the problem. The solution is to provide more ventilation so that the receiver can cool itself properly.
