Question about JVC TH-A25 System

Protection flashing and the system turns off

Hi, I've insert a cd with movie clips taken from camera. When I tryed to play the contnet, the dvd showd it as unknown format. And when I pushed the play button, the dvd turned off. After that I tried to turn on the system, but then I get only the word PROTECTION on the display and the system shuts down in 2 sec.

I unplug the system from the power outlet, and took out the cables from the speakers, left if for 2 days, but still have the same problem.

Could someone, help. Or should I take it to the service. Thanks.

You need to take it in for service. I work at an authorized JVC service center and can tell you that you now have a serious problem. It could be the amplifier or the power supply causing it. The protect circuit will activate for several different reasons and only a properly trained technician with the right tools can determain just what the problem is. I don't berlieve that trying to play the disc you mentioned would have any relation to the cause of the problem, it is most likely just a coincidence that it happened at the same time.

Before you take it in, try this.

Unplug all the speakers and then see if it will turn on and stay on. If it does stay on you may have a bad speaker. Turn it back off again and then connect one speaker at a time and turn it back on. If it shuts off in protect when you connect the first speaker, unplug that speaker and try another. If it still shuts off and goes to protect with a different speaker you have an amplifier problem. If it stays on with another speaker it may be the previous speaker is causing the problem, so take it in to be checked. Whenever you connect a speaker and then the unit goes to protect, it may be the speaker that was just connected that is causing the problem. This is not 100% all the time, but it is a pretty good indicator that is worth trying before spending money on a repair.

If the unit goes to protect even with no speakers connected you have an internal power supply or amplifier problem for sure.

Le tme know if you need any more help.

Hi there! I was using my hts3357 for 2 years with no problem. Now i have one: when i insert DVD/CD, it can list the files (divx) in it, but doesn't play. On the other hand, when i copy the "same" movies...


I would try a disc cleaner and using a can of compressed air. be careful not to let the device receive any of the actual propellant by using small bursts of air. otherwise if u hold the nozzle down to long u could do damage to the device other than good. sometimes the eye is strong enough or not dirty enough to read just the file portion but not good enough to read the movie portion. It can read the Usb part due to the reader using the microchip part in the player not the eye of the dvd player. A usb port and a optical drive work entirely independant. usually if it won't read it means it is either the eye dirty or the eye is not working anymore. independant electronic / tv repair shops can replace the eye for approx. $50.00. But if the cleaner doesn't help letting the player read the movies again. Then I would suggest taking it to a shop and having the eye replaced or just do a "tune up" on it.

On one particular DVD (UP from Disney/Pixar) a certain section keeps repeating. When I stop the DVD to try accessing the root menu it freezes up and the entire sound bar locks. The only way to resolve this...


Those discs have a very strong copy protection mechanism to avoid making digital copies on PC systems but some DVD players won't play them because of that, if you have the original movie, download a copy from the internet, burn it to a dvd-r disc and play it. It's perfectly legal because you already bought the movie. The downloaded copies have no copy protection and will play better than the original.
The PHILIPS DVD-Home theater players are specially picky about non-standar disk like the one you're trying to watch.
