Hi, first check all speaker cables for damaged insulation or exposed conductors that could short together especially if the wires have been extended. make sure all joins.or connections cannot short together. if the problem persists, then try disconnecting the speakers & powering up the unit. if the problem still persists then the amplifier has most probably failed

SAMSUNG HT-Q9 displays PROTECT and then switches off?


hello,
Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Usually a protect fault will indicate a bad transistor in the amplification section. I suspect that the control circuit is sensing a fluctuation in the power supply and going in to protect mode. (assuming that the protect circuit itself is working properly) If a voltage is too high the unit will go in to protect mode to prevent damage to the speakers and the rest of the unit. Expect a 60 to 80 dollar repair charge depending on how many parts need to be replaced and what the repair labor rate is in your area.Hope this will help........

I have a sumsung dvd home cinema system ht.thx25 when I put a dvd in it says disc unknown but when I put a free dvd in from the newspaper it plays.


Is the disc just a regular disc, not HD or blu ray?
Is the disc a region 1 coded disc?

If it is, the unit should play it fine.

Audio


Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

Samsung dvd/disc protection


Try a hard reset: unplug from power source, remove all cabling and wait for 5 minutes before recabling.

If that fails, it is a logic board error, in which case you are probably better off buying a new device..
