LG L2LC55 HDTV

My LG 42" HDTV (Model L2LC55-ZA.AECYLJ) has suddenly stopped working. I have power going into the unit but the red standby led is not lit. Any Ideas please? Could it be the internal power supply unit?
Thanks

If you do not get any light on the front panel, it means the 5vdc standby power supply is not working or failed main logic board, you will have to do the power supply inspection first.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

    Since the power supply and the processors will be running 24/7 the minute the TV is plugged into the outlet, any spikes, surges that come along will be fed into your TV and can cause the processor to get scrambled, I would suggest you to get good surge suppressor/AC filter unit such as PANAMAX, Belkins.

Does the screen quickly blink on and then off? Does the standby light slowly blink twice and then go out?If these are the symptoms then it is probably a bad led backlight strip.This was the fault with my lg 47ln540v led lcd tv.I have written this up in a previous post more comprehensively.Hope this helps..

No display issue


Red means it is going into shutdown because something is wrong.

It will not come on again until problem is found and corrected.

What is model number and do you have a warranty?

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.

LG 42in LCD Television - turning unit off


The amount of standyby power consumtion is minimal. The only way to turn it off completly is to disconnect the power from the TV. This will however increase your start up time when you want to use the TV.
