My bet is your power supply board has gone bad and some capacitors need to be replaced. If it's under warranty, take it to the shop for repair. If it's not, then you can replace them yourself or if you know some one who solders electronics they could do it also. To keep this from happening again buy a ups backup power supply which will condition the power to the tv and other components and save you alot of time and trouble later.

I have 47" LG LCD TV (47LD450-AU) and when I try to turn it on the red LED just blinks slowly. So I took it apart to check the power supply panel (P/N: EAX61289601/12) and it seems fine, at least all the...


These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy.

LG 47" TV takes about an hour to turn on. When you try to turn it on the light flashes green and red.


This means that the bulb is bad, and is taking forever to heat up. You need to get the bulb replaced to fix it.

This is usually caused by dirt trapped between the lcd filter layers and appears when the screen is pressed, pressing the layers togehter producing an internal dust smear..This can only be removed by stripping the lcd down and cleaning the filter layers

LG's are known for having bad capacitors in the power supply. These components will cause all kinds of problems like not turning on, no backlight or no video and are known to do this after the TV has been off for a few hours or days. You will need service on this TV.
