Re: Samsung / Hansol BN44-00428b

I recently had the same issue with my UN55D6420 after 2 years and 3 months. The television would intermittently reboot while watching and symptoms progressively got worse over the course of 4 months until the television would not turn on at all. I did unplug the TV for about 2 days and after plugging it back in, it seemed to work for about a day.

After reading multiple forums, I decided to replace the SMPS, which seems to have fixed the problem. There were no visible signs the board failed. If I get some free time, I may try to diagnose...
