If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent.

Try checking the fuses in the back of the tv

To turn on the Samsung HM3700 headset, slide the power switch up. (You can see it's location on the image below). The indicator light below the power switch will blink blue 4 times (purple or red means your battery is low). If it stays blue it is ready to sync with your phone.There are 3 ways to sync this device to your phone:

1. Once the headset is on, hold down the talk button for 3 seconds. (the blue light will stay lit for 3 minutes once you enter pairing/syncing mode).
   

• Activate Bluetooth on your phone and search for the hm3700 (keep them close to each other).
• Select the headset and enter a PIN number if asked.

2.) Active Pairing: Once you have held down the talk button for 3 seconds and the blue light is on, press and hold the talk button again to make the blue light purple.

• The device will try to automatically connect to your phone for 20 seconds. Your phone should not be connected to other Bluetooth devices during this process.

3.) FreeSync is an application you can download if you have an Android (from the Android Marketplace). It allows you to access your headset settings and I believe it can read your text messages for you (text to speech).
For more information the user manual for your Samsung HM3700 Bluetooth headset can be found here: http://downloadcenter.samsung.com/content/UM/201111/20111116163119314/HM3700_UM_America_B_Rev.1.0_110923_screen.pdf

Check the Blue button on your remote which says Psize right below the sleep button. That should change your size.

most likely you have a bad power supply look for bubbled caps on the power supply if you don't see any then I would replace the power supply. if you do then I would just replace the caps and that should take care of your problem

At this point it appears that your main board is probably bad. You most likely have a 5 volt scource going to the main board but its not powering up the set. The main board is part number BN94-00796A.
You might want to have a technician look at the TV to verify this as the issue before purchasing it. Please take a few moments to rate my answer. Thank you.

It's normally a power failure/surge on the main board. Most common with LG tv's of this type. Samsung tv's of this type don't actually turn off, they only go on standby, which is why you can turn the Blue Eye off in the menu. One solution to try (if you haven't already), is to disconnect it from the mains (this is also the only way of actually turning the tv off), leave it for 24 hours, and try again.
