Question about Televison & Video
There could be many problems associated with the same.The main problems are :-
1. Inverter has developed a problem
2. Powerpack that feeds the inverter has developed a problem
3. Their may be software problems to do with the mainboard
4. The backlight itself is at fault, or connections to the backlight are fragile.
It could be any of the 4 suspects in the list,the favourite is the inverter but it can only be diagnosed with specialist tools,oscilloscope volt meter temperature control solder station specialist semiconductors and passive devices and their is a device available now to check the backlight in situ.
A simple, but not 100% test to verify if it is the inverter, is to shine a flashlight into the darkened screen and see if you see faint images where the light shines - dim or darkened room. If you have some mechanical and electrical knowledge, you should be able to replace it

This is a classic switchmode power supply, shutting down to avoid a fire, explosion, or both. This set had developed a problem, that is so severe that the set must be shut down, This set should be removed from the Power, and in my professional recommendation, you should get a "Quote" for repair, from, an, Approved Service Center, this point is very important for a good result, Always contact, their local, "Head Office" Now, when you get the information you want, then you can decide as to repair of replacement. The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand.
Above is an LG, similar unit, training manual, this will give you an understanding of how it all goes together and works and how to approach servicing.
