Question about LG 47SL80 LCD TV

1 Answer

My new LG LCD won't turn on

I have a 47'' LG LCD tv that I bought new anlmost 3 months ago. Yesterday my landlord was checking the voltage in the outlets with a multi-meter and now my tv won't turn on. Normally when you press the power button it lights up a series of lights at the bottom and the clicks on. Now the lights at the bottom light up in sequence and the its like it powers down again. It also makes this clicking noise and the screen flashes grey for a second every once in a while. If there are any electricans out there that may know what the problem is, I'd appreciate any advice. I'm really wondering if the tv was damaged by my landlord or if its just a faulty tv.
Also as soon as I plug the tv in (right now its not plugged into the outlet) its automatically starts trying to power up even if I don't press the power button and it just tries to turn on over and over again, hence why its unplugged.

How can I fix my 42' lg it is stuck in standby mode.

I had the same issue with my 47' LG. If it's under warranty just have someone look at it. Mine wasn't so I took off the back panel, checked the power supply for the correct voltages coming out, which were unfortunately were correct. Which only left the main PCB, which was more expensive than a new TV and could only be installed by a "technician." However, the blinks could be a fault code. Here's the link to my question. have 47 LG LCD TV 47LD450 AU and when try to turn it on the red LED...

My 47' LG HD television worked fine yesterday and this morning the red light is just flashing. I just bought this television.

I had the same situation with my 47" LG. I opened the back and found 3 bad capacitors (bubbled on top). I replaced them at a cost of $1.20 ea at Radio Shack. I'm no expert at replacing these, so I let you tube be my teacher. I saved myself over $200 by doing it myself, not to mention there are some dishonest people out there that'll lead you to believe your TV is shot.. See the pics below of the "bubbled/bad" capacitors. These shoud have flat tops..Hope this helps....01b92fd.jpg

Sky code - LG 47" TV Model Code47LG5020ZB

If there is no code, then there is no code.

The only other option would be to buy a 3rd party remote that is compatible with both devices. Unfortunately there is no way to know if it will actually work until you try it.

Lg 47 inch tv sound

We had the same problem of pathetic sound quality and volume with a sony brava. Thats just the way they make tv's these days because most people buy a surround sound system as well. We bought logitec computer surround sound speakers for about $140 and plugged into the ear jack, problem solved, we have heaps of volume and stacks of bass.

42'' LG Plasma bought in Australia doesn't work in UK?

Find out if Australia uses a different standard of HD programming than Guernsey or not since it's not picking up any channels at all with an attenna. Does the skybox use only scart connections and that's how your small lcd is connected to it?
