Well I just joined in the world of broken Samsung's. Died Feb. 1st. I had three month additional warranty, but of course it died the day after. Same problem, no video, just audio.
However if you call 1-800-522-7341. This is the number for Executive Customer Relations. They extended my warranty and contacted the repair center for me. Probably won't be fixed by Superbowl Sunday though. I expressed my disbelief that after 15 months a 2400 set can die. I have to call back on Monday for additional help.

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.

Best send repair manual.
I have pics to show / identify problem but I cannot attach to my reply. Parts defective are: 4532M x 2 (UC2 & 3), diode next to diode RC22 & cap C35 and IC6 (cannot see part number). Board number is YPNL-M007B r1.0, also recognized L.G. Phillips part number: LC230W01-A2
My hands are not as steady as years ago to do surface mount solerering but my wife can as she has done this before being electronic equipment assembler.
As stated before I need to find source of what I suspect is short that had blown these components.
I bet a replacement board is more expencive than a new LCD TV!, but I want to resolve this prob and maybe help others...LG too.
Thanks Heaps Jaime867!

The flashing light indicates a short circuit inside the power supply circuitry. This type of repair is not a DIY without a multimeter, desoldering iron and hand soldering skills. I repair these power supplies, if you need further info write to firstname.lastname@example.org

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
Please post back what you find.

CLIP: red, to the left of each Gain control.
Normal indication: illuminates whenever the amplifier is driven beyond full power. The LED's brightness indicates the amount of distortion. Distortion that causes only brief flashing may not be audible.
During muting, the indicator fully illuminates. This occurs during normal "On-Off" muting.
•Bright red illumination while the amp is being used indicates either thermal muting or a shorted output.
•If the amplifier overheats, the fan will run at full speed, and operation should resume within one minute. Allow the fan to run, and make sure the amplifier ventilation is adequate.
•A shorted or overloaded output circuit will cause excessive Clip flashing and possible overheating.
•If distortion is audible without a Clip indication, the problem is either before or after the amplifier. Check for damaged speakers or overloaded signal source. The amplifier Gain control should be in the upper half of its range to prevent input overload.
