It only shows black screen after turn it on, there is nothing appearing except sign of SAMSUNG and buzz every other 5secs. I can't turn it off easily, have to take the battery out instead. Connected with laptop and again shows nothing on both. I think I may deleted some important part by mistake, is it possible to re-download to repair it by myself? Please give me your advise, it will be very helpful. Thank you!
Contact Samsung

That sounds like a capacitor or maybe a mosfet died. Usually only capacitors 'sing'.
first you need to confirm it is the backlight section that died. simple visual inspection. You want the monitor plugged into a running booted computer. If you have anything that will do dual screen that lets you know what and where something should be on the screen being tested.If not anything will work. Let the computer boot up and then you will need to get close and near an edge. What you are looking for is a ghost image of the normal desktop. You may even be able to see the mouse move around. This is the actual picture produced by the lcd. It is very faint. The backlight acts somehwat like a projector bulb and shines through the lcd panel. So if you can see anything then your backlight or the backlight power are the problem. I'm in BC so its hard to reccomend any place for parts. Most of the ones I have fixed the parts were out of California.Cost should be about $70-$100.
If the backlight isn't the problem then it is usually a power section problem. The parts are cheap but the time to find the bad one can cost a bit. If you can find a place to fix it get an estimate. Then check out the replacement price of a new monitor. The prices have dropped and sometimes it isn;t cost effective to repair even a backlight on some models.

hi,
your phone software crashes or corrupted. we can do nothing about it unless we have a special gadget used to fix mobile phones and buying it cost so much for that purpose only.
To save time and money, I recommend to have it reformat at your nearest service center or dealer if it still has the warranty or to trusted mobile phone repair shop.
Hope I helped you in some other ways.
Don't forget to rate me. Thanks...
Best regards,
John

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 off and 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 some time and then try again.
If you aren't tech savvy, don't worry, read the rest of this solution 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 the same 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 blue screen is known as the screen of death for a reason. You can try getting it fixed but most likely you'll need to replace it.
