SOURCE: I have a LG plasma TV. The picture won't come on but the sound does. It's a 52" model# 50pc50-ul. Production code 50pc50-ul AusYLSJR. Power 100-240v~50/60 Hz 4.5. Pcc ID: BEH50Pc5DUL.

This TV is 2007-2008 vintage. If you've had it this long without losing the picture, you've been lucky. Plasma and LCD panels are excited electrically to generate images, but they do not produce adequate light on their own to make the image visible. Thus, manufacturers install a backlight circuit which treats the LCD/Plasma panel much like a slide in a slide projector. When this backlight fails, you lose the visible image, even though the image is still on the panel. Older sets such as yours used florescent bulbs to light the screen. The use high-voltage inverters (ballast) that are the usual failure culprits. Newer sets use LED lighting. These use far less current and tend to last longer, but the jury is still out on their longevity as they are fairly new to the market. Inverters can be replaced, but be advised, as the florescent bulb ages, its color will change and it will affect image quality. So you may want to consider upgrading to a newer set.

My girlfriends LG wm3987hw just lost its power. the outlet is fine. there is absolutely no power getting to the machine. No lights, nothing. Anyone else have or had this problem? Fixable or DOA?

the wm3987hw has an internal fuse located on the "power connection noise filter", It's a transformer or something which cleans up the wall-supplied voltage a bit before it touches the expensive electronics.
You might just be able to replace just the fuse, otherwise the whole unit is part#6201EC1006T, about $50.
take the top off the unit (two philips screws on the top back) you will find the power noise filter on the top inside right wall of the unit. it's not terribly involved to do this fix yourself. 20minute job tops.

Few months old WM3987HW won't turn on - seems dead, unplugging and replugging won't work; outlet has power

Hi Rick,

I found your answer to another person's problem with the LG washer/dryer not turning on. We have the same problem. My husband found a piece of plastic near one set of the fuses that looks warped - like it got too hot. Is there any advice you can give? It's a piece next to the box by the main power cord with a metal coil.

My phone went dead, It wont even turn on. Even when it is plugged into the charger

It could be the power on switch that may be bad. You cant throw away a phone like this. So, show it to the LG Service Center and let them decide as we cant replace the switch (if need be) without special tools that most of us do not have.
