Question about Samsung HT-DM550 System
The home cinema system keeps cuttin out after 10-15 mins and says protection and goes on standby
Protect mode will kicking whenever a fault is detected.
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 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.

Protection Error means that there is a malfunctioning component inside your unit. It will go into protection mode and immediately shut down to protect your system from any further damage. Unfortunately you would have to bring it to a dealer or repair shop to diagnose the exact malfunction and that could be expensive.
