Why won't my lg tv turn on after I unplugged it and replugged it?

I unplugged my lg tv to switch out tv stands and then replugged everything back in. Now my tv won't turn on. I have checked the power supply several times and everything is plugged in correctly. Why won't my tv turn on?

the problem is in the power supply(they know about it good luck fighting them)but there is good news.you can remove the power supply and replace electrolytic caps,EC18,EC19,EC20 all of them are 1000mf at16 volt use 1000mf at25 volt.you can also go to shopjimmy.com enter model number you will see power supply part number MLT169B
it will be cheaper for you to replace the caps,the board cost about $80.00 from them

SOURCE: olevia 242fhd-t11 Has no power. Will not turn on

I am guessing that since you are checking other outlets that you are getting no STB light or anything. So you will want to start by looking at the SMPS on the unit and see if the 5A 250V fuse is blown or not. If it is blown then you can try replacing it but I would bet that it will just blow again. So you need to replace the SMPS

SOURCE: LG 32LH2000 My TV was turned of last night in the

most LG have a "vacation switch" on the bottom right hand side of the set very near that standby light.

it is placed poorly, where you can accidently click when grabbing the TV to move it or swivel it.

it is a toggle switch, a "master power" switch.

you may have bumped it to the off position. flip the switch, your standby light will come back on.

Lg tv does not turn on


The 55lh90 has a vacation switch on the bottom right corner. It's a toggle switch that interrupts power to the power supply. Should just need to toggle that switch to the "on" position, and everything should be back to normal.

I have a 50 inch LG plasma tv that is less than 2 years old. It use to turn on by itself throughout the night, and now it's completely not working???


Hi there
Try doing a system reset on the TV, by unplugging everything from it, then wait 3 minutes and plug the power lead in only. If it works, then plug everything back in one by one. If the problem persists it may be that the software has been corrupted in an update process, which can be performed at night via the aerial signal (this may be why it was turning on at night). In which case contact the TV manufacturer.
Hope this helps

Hi, i just purchased two LG LCD TV's the 26LD350 and the 32LD350 I'm worried that it does not have an off switch and only goes on to standby mode. you here alot about tv"s catching on fire because of this....


I have never heard of any LG TVs having a fire issue.
LG added this switch to help save electricity. "Going Green".
You see, this On/Off switch was added to kill the power to the TV when not in use. This switch stops the TV from consuming power by not giving it power to be in a “Stand-By” mode.
If your TV does not have this switch, you could simply unplug your TV to give you the added satisfaction it won’t catch fire.
I hope this information has helped.
Good Luck.
