Samsung HT-DB120 System - Answered Questions & Fixed issues


i had the same problem a prot display then it would shut down. turns out i had the sub disconnected(noise complaint from the shaking at my apartment complex) but the speaker wires for the sub connected to the amp or central unit. when i disconnected the sub i left the wires on the floor behind the sub separating the pos. and neg. somehow the wires got moved around and the pos was touching the neg. as soon as i noticed and fixed this problem the system was working fine. my samsung hometheater model is HT-BD1250

Disconnect all speakers and turn the system on. If protection turns on immediately, there is an internal problem. You will have to open up the main unit and check for defective components and poor solder joints. Keep checking operation without the speakers connected until protection stays off on startup

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections as a root cause for intermittent shutdown.

your cooling fan has failed. Check the back of the unit for exhaust air coming out. If not replace fan.

the player's amplifier is blown and needs to be repaired or replaced.

are all the speakers good?? discont all the speakers and see if all the lites come on. Then shut off and start to connect one at a time untill the unit shuts down and then you know you have a shorted speaker. If the same thing happens you probably have a power supply or an output stage falure and this should be serviced by someone who is quilified to work on stereos

Protection means the unit is detecting a short somewhere. Disconnect speakers and components and attempt to power on the unit again. If it will power on with nothing connected, repeat the process (turn off, connect something, then power on) until you find the bad component or speaker.

Surely you can find an NTE580 equivilant in the UK. This is just a 600v 3a silicon diode. I would think you could find a substitute for this at any electronic part supplier in the UK. The NTE numbering system is the same as the ECG system and everyone subs by these numbering systems. Good luck.

The surest way is to get a schematic and get the value from there if you can't get a number off the diode itself.

i have the same problem. was playing a cd for my son for about 20 mins. CD started skipping then froze up and shut off. When trying to power on the word "PROTECTION" comes on then shuts right off. Is there any solution for this problem? My husband bought this when it first came out over 6 years ago at $400. I bearly even use it. It's a waste to throw away. Please someone help. Thanks.

I assume it DID work at one time. You need to take it apart and see how the tray is driven... belt or gear. If belt driven you could replace the belt.
