Hi, I had the same problem on my Samsung.

I removed the rear cover and cleaned the cooling fans, there were (2), it has worked fine ever since.

Be careful of course working with electrical boards.

The problem is most likely the fuse connected to the power wires. You have to take apart the TV and follow the power wire to the fuse. Fuse number is T4AL/ 250v. It will be labeled above the fuse. We had the same problem. Also, check to see if the metal around the tops and bottoms of fuse are loose.
The way we fixed it was to wrap aluminum foil around the fuse and put it back in. It is only a temporary fix until we can get a fuse. Hope this helps.

LE40M87BD lcd tv will not switch on.it just repeatedly clicks but does not start


If you have soem expertise, and at your own risk, it may be a faulty electrolitic capacitor inside the unit. If a capacitor is bulgling or emitting black/brown gunge from a raised dome, (like a faulty tin of food) this is a likely culprit unless the switch itself is faulty. Doing this yourself with probabaly invalidate any remaining guarantee. With care, the most difficult thing is not to break the plastic surround.

Samsung dlp hdtv turns itself off


I worked on one of these for a few weeks. if you dont mind a little inconvenience you can remove the back lower cover and defeat the bulb door switch and it will run. the last one i had like this we could not find the problem even with samsung tech support. changed many parts in the mean time. its heat related but the lamp heat sensor in our case was not the problem.

Sharp TV switches to "input 2"


Mine does the exact same thing. I've had it for a few years no, and it just started doing this. It's so annoying. I don't think the weather has anything to do with it, though. It started switching itself just every once in a while, not it is almost every time I turn it on. Sometimes it takes an hour or so to start doing this, other times it's right away. Help!!
