Question about Samsung HT-DB120 System
I have the same problem on my unit. One day whilst playing for @ 20 min. the system stopped with "PROTECTION" displayed. On opening the unit I could not see any symptoms of the failure, like shorted cap or component and I checked all the power transistor modules with a multimeter and they did no indicate a short. After keeping it for 3 weks I powered it on yesterday only to notice a small whiff of smoke come out near the middle (biggest) power module. However no burning smell, nothing. This tells me that one of the output modules or transistor in the module is shorted. I did not have the time to desolder this and try powering on but this is the cause of the auto PROTECTION trip. Cause: Shorted power output stage that drives the speakers. I will update this as i have time (and patience) to desolder each module and test which one is fired up. Then the next thing will be to get an equivalent replacement transisitor to repair it. Anyone who can add more value to this is welcome to share their "repair" experience.
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.
