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 panasonic dmr-eh75v won't stay on. It turns off after about two minutes. What could be wrong?


Check the cooling fan on the rear panel. If dust builds up on it the fan blades won't turn and the unit will overheat and shut itself off.

My Digital Home system shuts dowmn after 20


FANCHK sounds like a message saying the internal fan is not running. Open the unit and have a look to see if there is a fan and if it runs when the unit is on. You can also try to turn the fan and see if it will turn easily or if it is seized up.

My Samsung HT-40 home theater system throws itself into protection mode and shuts down. I put a new fan motor in but it insists on shutting down anywhere from 10 to 60 minutes of operation. No dust...


The fan is going bad and if you have replaced it try to open the case and remove the cover over all the capaciters and what not and replace that fan in the back then cut a hole in the top of the metal case directly about the cap's that warm up and install a aditional fan to act as a chimney a little noisy but i did this and the player had been runing in aux and radio mode for a few days stright now no problems at all it's alot of work and skill but for 2 5-15 dolar fans sure beats the 160 for repair or buying a new recever! make sure u turn on the recever for 10 min if the fan is not turning by then its still not good

I have a samsung DVD Home Theater System HT-WX70. My son put a cd copy in the DVD player and PROTECTION flashed on the player and it turned off. I turned the player back on and took the cd out. ...


If it is, the protection message usually meant either a speaker had blown, or more commonly a wire to a speaker had come disconnected or broken/shorted.

Try unplugging the speakers one at a time, and if you have a set of speakers of the same rating to try, try plugging them in as you remove the originals (obviously doesn't need to be done in the setup positions in the room, just have them beside the player to check it works.)

This might then identify which speaker or cable is the problem one for you to replace or repair.

If this is the speaker overload/short mesaage as I think it is and the above doesn't cure it, it would appear the amplifier board has a short somewhere and that's an electronics engineer job time
Hope it helps!

Make sure the TV is set to output audio to the digital optical port. Then make sure you have selected the proper output mode on the home theatre. Unplug the optical cable from the back of the home theatre and see if the red laser is on (don't shine it in your eyes! :))

Hello,
Protection mode on a Samsung player most likely means that the unit is overheating due to a non or low functioning fan. Before taking it somewhere to be serviced turn the unit on and see if the fan in the back is functioning (it should be on whenever the unit is on). If it is not you can try gently blowing it out with a can of compressed air.
I am sure that you can have it serviced but it might be cheaper to purchase a new player.
Good luck and take Care,
-WN
