Question about LG 42LC2D 42 in. LCD HDTV

1 Answer

37LC7D LG LCD tv turn's on but remote keys and tv side keys unresponsive.

I turn on the tv and the led light blinks green and stays green. However, when I press the tv function and then the input button, it doesn't take me
to the input menu where I could choose tv input. The night before, I had the
input on av1 when I was watching a dvd. Now I don't even get a picture.

Please help. I only had this tv for a little over a year.

Thanks,

Lito

MY dstv DSDD 1132 decoder is flashing red and green lights but yellow light is steady. tv is black and remote not responding


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

My sony wega kf-50E200A tv keeps turning off. during each cycle the green light blinks 42 times and the tv comes on again for about 3 minutes and it happens all over again


More than likely the power supply is defective, but without testing and the repair manual that is just a guess, you make the decision to replace or repair the TV.

Veon tv manual


The eject button on the remote appears as an upward-pointing arrow with an underline - see below image. The eject button on the TV has a similar symbol.

However, I suspect that in your case, you might not be having a Remote.

This link says that your TV doesn't come with a Remote and DVD cannot be ejected without the remote :
