My LG TV red light won't turn on. although the plug fuse and the remote OK


Try manually pressing the power/standby button on the tv (side or bottom) the red light should appear, most modern tv's will turn on simply by pressing the channel up or down on the tv itself.. But unfortunately in most cases, this seems to be an internal surge and needs a professional to inspect..

First: service manuals http://elektrotanya.com/?q=showresult&megnev=lg&megnev2=32lc2du-u3%20&kategoria=tv&kat2=all
Second: most failure in power supply module is due to bad caps with domed top, you should inspect for that first, main AC fuse for main power.
Did you take out or look at the power supply yet?

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.
