Question about Olevia LT37HV 37 in. HD-Ready LCD Television
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, please read to the end, and watch the videos !
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, and even then, you should go OVER, not under the uF rating).
Most of the caps that go are 10V 1000uF or 3300uF.
I found some great videos of the procedure (for many Samsungs with similar 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.
the girl in video 3 had never even soldered before and was able to do this repair!

Hi, to be sure that the TV is on stand by mode you will need to operate the TV direct from the TV itself. To know if the remotes are still working or not..
After testing that if it doesn't function at all, that means the TV is experiencing Power problem...
You will need to contact your local repair man to checkit out for you..
Or if the TV is still on guanrantee, you couldd simplytake it back to where you purchase it from and they will fix it for free or replace it with another TV
