Question about Televison & Video
Tv will turn on and off, but does not display any picture or sound through the tv itself. (sound will work through external source, surround sound bar)
It sounds that the digital video processor section circuit has the fault. You haven't provided more details about your TV; brand name, model number etc; so it is not possible to post a solution to this problem. Visit the site named 'Electro-help' for more details.

Well I just joined in the world of broken Samsung's. Died Feb. 1st. I had three month additional warranty, but of course it died the day after. Same problem, no video, just audio.
However if you call 1-800-522-7341. This is the number for Executive Customer Relations. They extended my warranty and contacted the repair center for me. Probably won't be fixed by Superbowl Sunday though. I expressed my disbelief that after 15 months a 2400 set can die. I have to call back on Monday for additional help.

SOURCE: Samsung LCD tv wont turn on
what the full model number of your tv?
the clicking sound is the result of a faulty power supply, some capacitors(blown heads) on the power supply for the output voltage rail of the mains board need to be replaced.
pls rate me!

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

Not sure if this is the same problem, but I just moved and set up my Samsung 40" LCD and it has been going off and on by itself with the worst yesterday every 2-3 minutes. After speaking with a friend of mine who is not in the Tv business but just has good common sense, I determined it was likely a bad power strip. The bottom line is I replaced the crappy power strip (which was fully loaded with all 6 outlets in use) with the higher quality one I had in the other room. The problem is gone. I suspect the power strip was failing or real bad quality........try plugging the tv directly into the wall outlet first. hope this helped.

B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
