I have the 46in Samsung LN46A650. I have had the tv for about 6 months and one day it just started to do the same thing you stated. It will stay on for about 30 secs and then reboot itself. I have applied the latest firmware but it did not help. The technician is coming out in a day or 2 to check it out. Is there anything specific I need to mention to him. Did you ever get yours fixed? This is very frustrating because as you know, these tv's are not cheap. Previously I had a Sony projection tv that lasted us 10 years and is still working perfectly. Guess I should have went with another Sony.....
Hi, we're going crazy. After 3 attempts to repair the LN32A450, the TV will still decide to shutdown on its own and restart. The technician replaced all the cards. But again as we know they may send you some refurbished hardware, no wonder the problem is back.
One of the attempt was to flash the firmware with the latest code from the Samsung web site, to no success.
I wonder if anyone has been experiencing the same problem, and if so what was the conclusion or resolution (if any).
The TV is 6 months old, if this does not get fix soon, we'll apply the store "lemon" warranty and get a new set. But this time, even if it means putting my hands in my wallet, I'll have to change brand.... We lost faith that Samsung knows what the problem is and are not ready to restart the story with just another set.
If anyone can help.... tks in advance,
