Question about LG 42LF2500 42 HDTV LCD TV

Open Question

My LG 42LF2500, when i pushed the remote to turn on the tv, the stand by light turned off and on again,(as usual), but after the third time it turned off and the tv does not turn on. Remotely and manually. I changed the power supply board, but nothing. Is it the AV board, or the controller?

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.

What if the tv is off and the red stand by light is not on what does that mean


The red "stand by" light shows power is getting to the TV. If it is off, you may have no house power being connected. If you can get the red light to come on but your TV still does not turn on the power supply may have failed

My 32LG350 wont turn on. I just pluged it for the first time i bought it like a month ago. it was working but suddenly it turned off by itself and wont turn on either by pushing the TV on/off boton neither...


Try unplugging the the TV from the power outlet for 30 seconds to a minute and plug back in again. Try to turn on again. Some TV's have to be in a "ready mode" to operate by remote - so besure it is in that mode - or use the power button on the TV.

Good luck!

Need Time Warner Remote code for LG 42LB5D HDTV


For Time Warner Cable digital remote controls to work with your 42" LG HDTV, do the following:

1. Press "TV" and "OK" simultaneously for 3 seconds, until the button "tv" light on the remote is on.

2. Enter the TV code. In this case, it's "113". With the right code, your component will turn off. Quickly press the power button on your digital cable remote to turn it back on. Press the "TV" button again so that the remote saves that code.

3. You should be done.

37'' LG lcd tv, no power


I just want to clear things here.
The stand by light will remain on whenever the tv set is turned on by a button on the side of the tv.

Then use your remote to turn on the tv, but wait as it can take 10secs before you get a picture.

LG 42 LCD no sound or picture


Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.
