How Long Can I Keep My LCD TV On At One Time Without Overheating Or Other Problems Arising?

Question

There is a problem with my Samsung LN-46A650 Flatscreen LCD TV's Power supply which I have read is a chronic reoccuring problem with samsung owners due to cheap power capacitors that were used to build these tv's.

When I turn it on it clicks but wont power up. As per my research it takes longer and longer to turn on until it doesnt anymore. It took 10 minutes just now and it IS taking longer and longer. I dont want to turn it off becuase I dont want it to NOT turn back on.

HOW LONG CAN I KEEP IT ON WITHOUT OVERHEATING?

I am thinking about pointing my air conditoner at it to keep it cool.

Opinions?

Answer 1

Let me point out this, my dealership (Toyota and Scion) has a Pioneer Plasma monitor that is running 24/7 since 2005 and have not has one trouble. In the same token you don't have to worry about the tv over heating, as a car would. I would email Sumsang and explain the situation to them and can recommend a solution, if it's under factory warranty they will repair it. I have a 58" Sumsang Plasma tv for over a year and half and don't have problem of turn on and off instantly.

Answer 2

I would not do the plug, unplug exercise. As for keeping it on, there generally is no limit. You can leave it on until the backlight burns out, maybe a few years. This assumes that your set is adequately vented so that heat can escape from the top, as yours probably is. But leaving it on for long periods serves no useful purpose except to run up your electric bill. The typical LCD set draws about the same current as a 3-way light bulb turned up full, or more for the larger ones. As to your problem, I don't believe there is a difference between turning it off for 5 minutes or 5 hours. If you can't turn it on with neither the remote nor the power button on the set, you have an obvious repair issue (hopefully, it's in warranty).

If your TV is under warranty, simply fix it now for free.

If not, this is a good time to fix it before more damage is done. If it is a known problem, Samsung may even fix it for free even if you are past your warranty.
