You should always post the model number too but we at least know it is an LCD set so the below-pasted information applies.

If it's failing to turn on, the main power supply is probably at fault and without some technical background and a couple of test instruments, you will not be able to do the repair yourself.
What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for a separate board with mostly larger components on it; it will have a ferrite core (no laminations as with a line-frequency part) transformer on it and several larger capacitors which are cylindrical and mounted vertically to the board.

Before touching anything inside, especially on that board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.

If you see signs of overheating such as discoloration of the board material, the PSU may not be repairable but if you can find a part number on the board, you might be able to buy the power supply from the mfr. and install it yourself but it will likely have the same problem eventually unless they have altered the design or improved component quality.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the main power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload and the power supply for the backlight may be at fault.

Why does my Sony Google TV NSX-46GT1 46 in. HDTV LCD TV powers up, displays application screen on bottom, makes a computer chime and shuts off completely, and starts the same process over and over aga


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

My emerson tv standby light is on the power light flashes twice


Mine stayed in stanby mode and all I had to do was to switch the plug to a different outlet. The power strip it was on wasn't providing enough power. It worked fine for a month before I had a problem.
