No sound or picture, cannot turn tv off, samsung 32" flat screen

SOURCE: Closed Caption

Yeah, I'm now believing it's the tv. The captions on the other tv in the house work great. My samsung is only 2 yrs old. This model was 1080 i...Kinda of costly. Still no solution???? CR. LEE

I lived with it for about six weeks, then took the back off the TV. Just now it seems to be fixed, but I don't know if it will last.

I disconnected the wire leading to the channel up/down, volume up/down and source board, turned on the tv, turned it back off, reconnected the cable, and everything seems fine now.

Most likely the set has lost vertical sweep or the feedback from that circuit. This will shut the set down to prevent a horizontal line from burning the face of the CRT. This will have to be looked at by a technician.

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for 5 mins, then try.

If you aren't tech savvy, this unit needs to go in for repair.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for different brand, but same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.
