Question about Samsung HT-DB120 System

1 Answer

Protection Hello, I have a Samsung HT-DB120. It's a nice unit, that is untill it quit working. When its in stand by, I go to turn it on and the display says protection. I have some experiance with electronics but I haven't figured this one out. I first checked the fuses, all seem to be ok. Could it be some thing in the IC, Power supply? I don't know, any suggestions would be great . Thanks in advance, Joe

Re: Protection

Try disconnecting the speakers one at a time. You may have a shorted speaker. If all are disconnected and it still does not come on, then, you probably have a shorted output.

When i switch on it will appear protection and goes off

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

HT-Z320 displays PROT code and then shuts down

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

Protection Error on power up

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

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.

cheapest and most logical start to the solution is to replace the optical block. looks like its focal point is drifting at a certain temp.almost impossible to pick up that problem without having that problem before. if i can advise,when you recieve the new part, unsolder the small bridgepiece that they put in for protection. if you dont, the unit will never work.
