SOURCE: tv keeps clicking but won't turn on

Over time TVs can dry out and then stop working. Switch it on and pour some water in the pack. About 2 pints should do the trick. You'll be back watching 100 channels of diarrhoea in no time.

SOURCE: my tv turns off by itself and makes a clicking noise

Most likely it has some bad capacitors in the power supply. Flat--panel sets are VERY hard on capacitors, due to the fact that the "rising heat' from the set "cooks" the caps and they fail VERY early.

SOURCE: Samsung LN-T4661F - When I turn the T.V. on, it

In this case, I believe it is the power supply board; more specifically the capacitors are failing. When you have the clicking problem and the long boot up times this has generally been the issue.

When you have video display problems such as shadows and lines that go away after warming up it is usually the LVDS cable and T CONN board going bad.

I had the shadow and line problem and replaced both the cable and board for $120 and that fixed my problem. Since I had the TV apart, I went ahead and replaced the capacitors so I wouldn't run into that later. You can find the parts numbers for the LNT4661F cable and board below. You can find links to you tube ( Part 1 & 2) to show how to replace the capacitors. Good luck.

Samsung PS42Q97HD TV clicking


Its a capacitor on the back of the tv, apparently they dry out and can explode. Our clicked for about a week before breaking, so i'd get it checked out before it breaks. Ours is being replaced under warranty.

TV shuts itself off


Something is overheating or you've got leaking capacitors somewhere. I'd start with the ballast board. Its directly underneath the lamp housing. You can access and remove it through the lamp door. Replace that and if that doesn't solve the problem, comment again, and we'll move on to more complicated repairs. You haven't noticed any weird noises, humming, screeching or similar oddities from the set? Turn the set on with the lamp door open and bypass the switch with a piece of tape, if you hear something like a hum, you may have a bad color wheel motor.
