Question about Televison & Video

3 Answers

My Samsung Home Theater System is having problem with its cooling fan. When I turn it on, it stays on for about 20 minutes and turns itself off as if I pressed power button on the remote. (So it is not a sudden power-outage type of situation) When I try to turn it back on, it now stays for only 5 minutes before the same thing happens. When I try again, it stays less than 1 minutes and turns off by itself. Then it happens again and again. I assume there is a problem with its cooling fan, and it cannot remove the heat properly. Is there a way to fix this by myself without having to repair it by professionals and pay $$$?

Its better to place a heat sync or replace the fan to much higher cooling capability. Try to unplug the power of the unit for few hours.

My samsung home theater system plays about 15 minutes and then just shuts off.


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Error fan check message always appear when you turn the DVD on

Cooling Fan


The cooling fan supplies cool air to the unit to prevent overheating.

Please observe the following cautions for your safety.

Make sure the unit is well-ventilated. If the unit has poor ventilation, the temperature inside the unit may rise

and may damage it.

Do not obstruct the cooling fan or ventilation holes. (If the cooling fan or ventilation holes are covered with a
newspaper or cloth, heat may build up inside the unit and fire may result.)


So look at the fan and make sure it's turning. Pick out the dust balls. Give the system room to breath (Page 13: 4" clearance from the fan)

I turn on my system and it works ok for a couple of minutes. Then it started showing "fan check" for another minute, then shuts itself down. Is it the fan? How can I check that?


To answer your question, yes, it is the fan. There will be screws holding the top cover onto the unit; remove these, and find the fan(also remove any dust you find inside, as this also could render the fan useless due to airflow problems). Make sure it's not jammed or clogged or anything such, and plug the unit in, turn it on, and make sure the fan turns on(in some cases, it waits a maximum of one minute to do so.) If it does not turn on after one minute, then a new fan is needed. Any fan with the same size and power connector will do.

I have a samsung HT-Q100 and its plays well but it will turn off itself after 45 minutes of playing time. I've check the back of the player and it heats up really hot( on the right of the fan at the back)...


If the fan is not providing sufficient cooling (it could be that the fan needs replacement), try placing a portable fan where it blows on the back of the unit. If the unit continues to work, you'll know you need to replace the fan within the unit.

Fan chk problem too


it means the home theater is over heating and the unit will shut down to prevent any damage. This can happen if the unit is stacked along with other electronic devices or the unit is in an enclosed area that prevents the unit from cooling properly. To decrease the chance of overheating, relocate your home theater to a more open area.

If the home theater display reads PROTECTION every time you turn it on, no matter where or how the unit is placed, it needs service. To set up service call Samsung Customer Care at 1-800-SAMSUNG (1-800-726-7864). Have your model number and serial number on hand to set up service.

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.

System turns off by itself


My unit said "protection", "goodbye" so I opened it up and found a capacitor to one of the speakers had blown, right by the fan. It's a 35 cent part and a simple solder job. The hardest part was getting the face plate off the dvd tray so I could get to the circuit board.
