My Samsung TV got stuck in the service menu and as I was trying to back out somehow a MiCOM upgrade began. The TV then froze so I pulled the power and after a little bit, plugged it back in and TV still won’t power on. Contacted Samsung support and they had no advice whatsoever. The TV does have power going through it as the USB dongle with the TV’s updated firmware on it is connected and in bit to e screen itself is off. And the red sensor in the bottom right corner is off as well. Any ideas on how to restore this?

LCD TV's have a known problem with capacitors going bad. If your Samsung LCD TV won't turn on, or makes repeated clicking sounds, there is a very good chance that you can save hundreds of dollars doing this simple repair yourself.

I know, I know. You're thinking, "Tinker inside my LCD HDTV. Are you crazy?" No, I'm not crazy. This is a repair almost anyone can do.

Don't have a Samsung? The steps below will work for you as well

You sit down and get comfortable, ready to watch your favorite TV show or movie. You turn on your TV and...nothing! Unsure if you hit the power button, you try again...again, nothing! But you do notice a clicking sound emanating from your TV.

"What the heck? No...Oh, crap!"

HDTV's aren't cheap. Most of us have to save, or at least be prepared to spend $800-$1000 on new one. Heck, I'm sure many of you don't savor the idea of spending a few hundred on repairs. Well, I have bad news and good news.

The bad news is that you're the lucky owner of a Samsung LCD HDTV that has a known problem with capacitors going bad after 2 to 3 years, and If you did not purchase an extended warranty, then you might be headed for a $200-$400 repair bill.
