The most likely cause of this problem is the power board.

Take the cover off, make two-three good high-resolution up-close shots from different angles and send them so we can tell you if there are visible issues with it.

For more detailed troubleshooting you'll need a voltemeter and tons of patience.

These 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 stage 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, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

With no stand by light, you are not getting power.Unplug TV and check fuse on power supply. You will need a meter to look for shorted components and possibly leaky/bulged capacitors that are killing your power supply. flickering could be part of the bad power supply or possibly a problem with YSustain area of your TV

Tried to turn on tv and the green light switches to red and flashes 3 times...it is only 6 months old , would that be under warranty


Sets usually come with a 1 year warranty. It should be under warranty. Check the owners manual. It states it in there.

I have an LG 17LX1R LCD TV/monitor that won't go on. The power light on the TV flashed red . . . but that's it.


My LG 17LX1R had a almost the same problem. Red standby went to green for 1-2 seconds then back to red standy. Turned out to be bad caps on the power supply board. Yours is definately going to need to be opened up. Not a generic fix. You gotta ask yourself if its worth fiixing a 6-7 year old LCD tv with limited LCD life. New ones can be had for about $130-150.

Sky remote code for LG 42LC46 tv


After spending hours on this I found that code 0206 worked on my sky+ remote(with LG 42LC46). On an old sky remote, prior to version 4 (inside the battery compartment), just use 206.
This code was actually for a LG 42PX5D but it works perfectly on my tv.
