LG 32LB75 TV stuck in stand by and won't switch on!!

It has very old components and is in need of repairs and some tlc.
Take it to an old fashioned TV repair shop, find an engineer who is over 50 years old and you should stand a chance of success.
You can then look forward to large electricity bills from using it.

If you mean the original stand, place the TV LCD panel down on a table that is covered with a soft cloth. Look at the bottom center of the back of the TV and remove the 4 Philips head screws. Once the screws are removed, pull the stand away from the TV. The base can be removed from the stand body by removing another 4 screws that are at the top of the stand body.

See page 12 of the user manual available from the LG support page: https://www.lg.com/us/support/product/lg-42LG50.AUS . The current link to the manual is https://gscs-b2c.lge.com/downloadFile?fileId=KROWM000196216.pdf .

I hope this helps. If you have put a third party VESA stand on the 42LG50, you may have to remove the TV from the stand to reach the mounting plate.

Television is not the main remote control from behind or the side

Hello rogerstanila,
if you have tried unplugging it for a while and if there is still no change then it could be your main board. Unfortunately to fix this could be costly. See if you can find a repair tech that will do a diagnosis for free. But there has quite a bit of problem LG tv's being stuck on standby especially the LCD tv's, Other than this there is not much you can, maybe changing the battery of the remote and just keep trying to click on and off. If it is plugged into a cable box, try unplugging all of that for a while. Leaving it unplugged for a day won't hurt. If nothing else then it could be your main board. You could replace it but as I said before it could you couple hundred dollars. Hope this some what helps.

it is more likely that it detects shorted or overload, so it goes inti shutdown to protect the set from futher damages.
You will have to do in-depth troubleshooting, starting at the power supply module first.

My TV done this one week ago. I unplugged it for 10 seconds and then plugged it back in. Turned it on and it worked fine. Guess it reset itself.

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.

Try unplugging it, and then plug it back in, see if that resets the TV

There are four screws in the back of the TV above where the stand is. Inbetween the screws is a metal handle that pulls out. These four screws need to be removed and the metal handle pulled out. Then the TV will come off the stand.
