The blinking red light signals the fact that the power source is in protected mode - it's fully functional (as the green light also shows) but has been shut down by it protection system.
The protection system of the source is engaged when 2 things happen: either there's a short on one of it outputs (you will have to test the output voltages to identify the failing board and from there if the board can be repaired - start with the inverter) or if the processor can't load the firmware - this is almost always caused by a hardware failure of the processor and in that case the mainboard will have to be replaced.
In that case it will cost you around $200 to get a replacement board, plus the labor. Now you must decide if the tv is worth that amount of money - in my opinion it doesn't.

Lennygunsch,

You have a bad mainboard. This is a common problem with LG and sister Vizio models. I guess they are cheap though! You can get a new board at http://www.encompass.com or http://www.shopjimmy.com . Be prepared to wait though as there are so many problems with these units that they are trying to get the boards from the factory.

Thanks for using FixYa and for the great rating.

Replace capacitors c520 and c126 to get your power working again.
Also make sure that you don't have a broken green 3 inch jumper wire broke that lies under the heat shield in the top right corner. The wire should be glued to the board for stability. It sometimes breaks loose and will cause the TV screen to stay off.

The front LED flashes red & blue when I turn it on. What does this mean?


LED Indicators - LaCie 2big Network
The LED indicators above the drive bays and the front LED indicate drive status and activity.
During Startup
  • Front LED – blinks red/blue until both disks are powered on, then turns solid blue.
  • Rear LEDs – blinks red/blue until corresponding disk is powered on, then turns solid blue.
NOTE: If the device is not able to initiate the boot process following disk startup, the front is solid red.
During Bootup
  • Front LED – solid blue
  • Rear LEDs – solid blue
NOTE: If a disk is failing, both the disk’s corresponding rear LED and the front LED will be solid red.
During RAID Synchronization
  • Front LED – solid red
  • Rear LEDs – The LED corresponding to the original disk will be blinking blue and the one being synchronized is blinking red
  • Once both disks are synchronized, their corresponding rear LED and the front LED will be solid blue.

LG 26lx1d tv will not turn on. Power supply is fine. Remote control is working. Also tried on/off button on tv and tv does not turn on. Red light blinking on front bottom of tv near remote receiver.


Have an LG26Lx1D for about 3 years, dropped off by my son.(Figures).Power light just blinking, but went back to red.Removed back panel, and metal cover. Just above antenna/cable input, its a small fan,mine was full of dirt. Blow off dirt, and make sure its turning freely.
Install back the covers, an voila....its a miracle...its working again.
Good luck

LG 26LX1D won't turn on.


My LG 26LX1D is the UA Version.

The solution for my problem was unclogging the Small Fan by the Main Panel, on the opposite side of the TV as the Power Board.

This is My Story.

The TV I found at the dump seemed good, but would not turn on.

Two LED's showed up on the front panel of the Television. First, the Red LED (on, off), then the Green LED (ON), then the Red LED (blinked) while the Green was still on.

I removed the back panel and saw that there were NO SIGNS OF BAD CAPACITORS on the Power Board. I plugged in the TV once more to see what would happen.

I noticed that there was a SMALL FAN which did not move when I plugged the power source to the outlet. This Fan was CLOGGED WITH DIRT.

I unscrewed the Fan from it's place and set it on a dish to act as a buffer against the main board. I then proceeded to clean it with a Vacuum Cleaner and a small Flathead Screwdriver.

I now own a FUNCTIONING LG 26LX1D-UA, RESSURRECTED!

LG LCD TV Standby Light Flashing Red Continuously


I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.
