Do a factory reset to this set, and then check. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

On the TV's user menu (press "menu" button) look for "Captioning" or "Closed Caption" choice. If not immediately in view look in "set up" or "Audio"...it should be in the menu. Find it and then turn it off.
Your tv might be in showroom mode. Use the remote to open the main menu, go to picture, go to mode, go to power up and make sure that home is selected and not showroom. Many of the controls are disabled in showroom mode.
This the common problem for Olevia TV, open up the back cover, locate the power supply board, look for the electolytic capacitors top that is slightly domed, replace them, they usually 1 or 4 that is bad, buy your replacement's at Radio Shack
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. http://www.youtube.com/watch?v=Mm51C_RDIZE http://www.youtube.com/watch?v=BNHHrgX_6cs&feature=related http://www.youtube.com/watch?v=8l0AUj8QUkg&NR=1&feature=fvwp http://www.youtube.com/watch?v=Y7b_nTaZYcU&feature=related
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!
No,the LCD screen panel can't be repair only can to be replaced,but it is in a limited parts in the productions and 90% important to the whole tv,by replacing the LCD screen panel,will cost the same as a new tv.No the LCD screen panel internal radiation,will continue to leak and slowly getting bigger and bigger.Sorry this tv is not worth as a whole tv anymore.These problems involving with the tvs LCD screen panels or any other tvs screen panels for that mater damages or broken tvs with a screens panels.Will be end up as salvages tv for those electronic's boards for spare parts for other tvs,that it.
I assume your sure your panel is defective. I checked with all my parts providers and could not locate a panel. Normally the panels cost as much or more than a new set making it uneconomical to replace them. For instance a 40 sony panel will run 1100.00 and the tv around 850.00. Sometimes you can find used panels but always the risk they dont work. Most televisions on ebay that are selling for parts have defective screens. Sorry... If your not sure your panel is bad list the symptom and we can go from there..
When you have strange problem like this, power supply module will be the first thing to check for steady DC. Since this company is no longer around and parts are getting hard to come by, the repair shop will not even try to do component level repair on it due to time consuming process and no schmatic available.
There may be not much you can do.
check the TV power cord first., try to plug any other appliances on the same surge protector or outlet, like electric fan, electric iron., see if's work., if it does, probably the power supply of your TV is in trouble.
i am afraid you can't fix it at home, when the light goes on had came a current shock, if it is within the warranty period take him to the garage to repair, Maybe they will advise you how to request compensation from the supplier of electricity if it was their fault. good luck.
