SOURCE: Have LG 42LD450-UA lcd tv that has no picture or sound. When plugged in the red power light comes on but when it's turned on the red light flashes very slowly continuously. Thanks in advance

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 section 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 procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details of many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

My 42 in lg tv model number 42ld450-ua went off


Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

LG tv is in protection mode, I guess. Can get it to work sometimes for a few hours, but always turns itself off and power light blinks red after that


Hello People, I have today took the back off from my LG 42LD450 TV. I had problem like screen goes from picture to like white or green lines. The tv has no functions then auto shuts off with red blinking light. I was concern and I notice my main power supply cord. The several gray little cords bind together are badly chewed. plus a black cord that is chew too. a more thicker cord. I indicated that if I replace these wires, perhaps my tv will start working correctly.. Yes we have little mice issue and this tv sucks cause there a small space were the stand goes at. can't close it either. Here's some pictures I took. sorry if blur. battery was low at the time. couldn't get flash or phone to focus.

20170522_212905 copy-n1wp1d2yjqbukp0mguo5hfo5-3-5.jpg Anyways I would try to look at these wires if you are having same issue.. I found the gray wire only cost $25. So I'm guessing the larger wire be around $25 or $30+ I hope this helps anyone that having this issue. Good luck and hopefully good luck to me.

When I power on the TV, the blue light comes on then a red blinking light comes on. The TV has no sound or picture.


You need to troubleshoot it to narrow down the problem. It may be in the shutdown/restart mode because it senses shorted circuits, or it may have failed power supply.

Lg 42ld450 is not turning on. It keeps flashing "red" in what appears to be the power saving mode. Any ideas??


The power board or power supply could be the likely cause of the problem. Have that checked out.
