The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main 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. Pull up older posts. http://electronicshelponline.blogspot.com/ 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. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

SOURCE: 42 inch LG Plasma TV Lost Picture

Hi it sounds like it has had an elctric fault like a resistor failing.
The click you heard would be a internal switch that cuts off the elctric supply to the screen to stop furthe damage hapening.
It could even be something simple like a bad solder and in that case will need locating and resoldering.
How old is the telly and how often is it used.
When you switch it off leave it off for about an hour then try again if you have allready done this then it probably is a blown resistor are you sure nothing has been pressed on controll have you tried seeing if you can acess the menu screen via the remote and see if that comes up on the screen let me know ok

  • please go to LG service centre rather than going to local repair centre.
  • as i think that they give first service at some concession rate.
  • i do not think it is much.
  • as no part in tv is that  costly
  •  except crt which is rarely fails in two years time.
  • please call them they will come to your home and will do that.
  • it is not major problem.
  • hope this will help
  • good luck.

Funny noise on LG TV


This is a problem with alot of TV sets. Most of the time, women can hear this alot better then men because they have better hearing then men. There is what we call in the buisness, a "singing coil". The problem could be simply the coil is singing and will need to be replaced because the windings of wire that makes up the coil is not wrapped tight enough or this noise could be the sign of future problems to come as a bad switching power supply capacitor or a capacitor going bad. I am sorry to say there is not alot an end user can do except call out a tech to have a look. Good Luck
