Either a problem in the power supply or with the main board that controls all functions---if you have to unplug it that points to a control issue of some kind.

Most likely a shop repair----find and replace the board causing this.



Google the model number with "parts"---there is a seller who sells all the boards listed by model number---you can see what boards it uses and the cost of each.

SOURCE: Powers on, screen flashes Akai screensaver and then shuts off

Take the unit into the service center - have the service center diagnosed the problem - they will order the part - but the parts are not available - DONT WAIT - The manufacturer must exchanged the unit because the the manufacturer must provide the parts for up to 5 years by law after the the tv is manufactured. Have the service center provide you with a workorder stating the television is not repairable because the parts are not available - then call 800-726-4405 - they will start hte process to exchange the televsion - LONG PROCESS to get an exchanged television

SOURCE: LG 47" LCD shuts down several times w/ blinking red light.

Granger1212 we had the same problem. We called LG and although our LG was out of warranty by 4 months, we were asked to supply our proof of purchase and LG sent a serviceman to our home and in 2 days we had our television back working wonderfully. It's the power supply, call LG and BE NICE, I'm sure they will fix it.

SOURCE: My 47' LG HD television

I had the same situation with my 47" LG. I opened the back and found 3 bad capacitors (bubbled on top). I replaced them at a cost of $1.20 ea at Radio Shack. I'm no expert at replacing these, so I let you tube be my teacher. I saved myself over $200 by doing it myself, not to mention there are some dishonest people out there that'll lead you to believe your TV is shot.. See the pics below of the "bubbled/bad" capacitors. These shoud have flat tops..Hope this helps....01b92fd.jpg

Hi Jamie, welcome to fixya

I have here a procedure that works well on Sylvania tv`s , since both brands/models are made by FUNAI , it may work on yours as well.
With the tv`s original remote control and in one sequence, press the arrow left then right and power.
As i said this works with sylvania but will it work on yours ????
Nothing to loose by trying i guess :)
I`d like some feedback on this if it does.

By the way this problem is known to occur after a power blackout or if the power cord or power bar is turned off while the set is playing.

Hope this help and good luck.

LG shows it will lose display in 3 seconds


hi the tv has detected a fault with the back lighting, now it could be a problem with the voltage to the back light or some of the leds in the back light have failed, it will turn off the back light when it finds a fault. behind the screen there is rows of leds on strips and they all light up when the screen is in use. and the main board knows they are lighting up by the voltage its using. when to many leds go out the voltage is too high so it will turn the back lights off to save them. also the same if the power board is not supplying the right volts. say the volts need to light the back screen is 64 volts and its only giving 62 volts the power is not right so it shuts down. same for if the volts go up to 64.5 volts it will do the same. hope this helps you under stand.

LG 47LE5400 loud POP, shuts down, immediately comes back on OK. Happened 4 times on two months. Dangerous?pman407@


That is interesting.

Only thing I can think of is electrolytic or other non-essential filter capacitors bursting.

It is hardly dangerous for you, but it is most likely dangerous to the TV itself.

I'd open and inspect the boards for signs of bust components.
