Question about Samsung Ht-d5500 5.1 Channel Home Theater System With Blu-ray Player
Nothing is connected to it. not even speakers.. immediately goes into Protect mode and powers off...
Probably power supply board. Remove and inspect for burns - front and back. Can be purchased for $50-60 on line. Google the part number.

If this happens only when connecting the receiver, chech the receiver cable. If the cable is fine, receiver connector at the back of receiver is faulty.
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 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.

sounds like one or more speaker cables are either shorting or not connecting...I know you have checked all cables, but if it was defo ok in the other room, theres not much more that can be wrong. (i'm assuming that you turned the device off before dicsonnecting everything).
If you are using the same speakers, did a speaker get damaged in transit?
you can test your speaker cables and speakers with a basic Ohm meter..disconnect each speaker connection from the unit and test for resistance..should read similar ohms to what your speakers are (usually 6-12 ohms in home hifi). if any connection gives a significantly higher or lower reading, thats that culprit.

The amplifier has a bad channel, the power supply is bad, or the amplifier is drawing too much power.The speakers could also be wrong, if they are not the speakers that came ith th unit, they will need to be replaced. (Any speakers within the specs of the amplifier will work, so to that end the system is customizable. You can go to Samsung.com to find the amplifier's wattage per channel, but the speakers you get MUST be 3 ohms impedance.) I have an article/tip/how-to as to wiring multiple speakers to one channel.
