SOURCE: 42 inch LG Plasma TV - Lost picture

Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

SOURCE: 42 inch LG Plasma TV - Lost picture

Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman

Try One of your working TVS and connect it to your cable outlet of the TV that is having problems. If that TV Does not work then there may be a degraded fitting or the Leg coming of the splitter to that outlet could have a Low Signal Problem
Next Take the First TV that was not working properly and put it on the cable outlet of one of the TVs that is working properly and if the TV set works on that Channel then you know it is not your TV that it must be the cable

Change the main board if you have good picture and sound. If you don't have picture and sound, the inverter will also need to be change.

SOURCE: LG RU-42PX11 42 plasma TV has black bar

it seems to be a bad connection somewhere but I disconnected the ribbon cable and got a verticle line of snow instead of a blank line. the line is about 34 mm wide and starts 285 mm from the left edge starts on the Blue and goes to the Red pixels. so if they are 1mm wide that would be 34 bands of color.

I would sure like to figure out the solution to this one or I got a TV I need to throw away cause the o'lady is gonna bust my balls if I can't fix this!

My 55inch LG 3D smart tv is not working properly. When you turn the tv on the LG home screen comes on for a few seconds, and then the screen goes black. What is causing this

it's set to the wrong input device ? the one you currently have it pointed to has no input

also it's possible that cable plugged into current input channel has gone bad or become disconnected from it's source
Hdmi cables are unfortunately famous for this as they have no Lock device to keep them inserted into ports

most TV's nowdays shut off if not provided an input for a few minutes

Lg plasma tv 42PA4500 no picture

1) Make sure it is plugged in
2) check the power cord to make sure it is tight on both ends
3) plug something else into the wall outlet to make sure that it is working properly
3) If the power light comes on than it is not a power problem, check the cords to the cable TV or to the DVD player, or whatever it is you are trying to watch
4) If the power light comes on but the screen is black, use your remote to make sure you are on the correct input channel to watch whatever you have hooked up to the TV. For instance, if you are watching cable, and it is plugged into input 4, you need to make sure that you have input 4 selected or else you will get a black screen.

We received an LG BD 330 blu-ray player as a christmas present since we own the LG 42LE5400. But whenever we go to watch either a DVD or a Blu-Ray disc, one of two things occurs: 1. The picture on the...

That does ring some bells. Does the tv ever do this when you are watching anything else on the HDMI input or any other inputs, apart from the DVD player as the input source?

The screen is black and a little box that says no signal is moving around on the screen

Check your inputs. The no signal box means exactly that - there's no incoming signal for the TV to decode. So you've either disconnected a cable somewhere or turned off your input device.
Try changing the inputs on the TV (this will be a button saying input or A/V)
Try changing the channels
Check that your cables are correctly connected and that whatever you are trying to use (dvd player, PS3, etc) is turned on.
Check that your TV is tuned to the corresponding input it is plugged in to (if you plugged your DVD player into HDMI input 8, tune your TV to input 8)
Hope this helps.

The LG symbol only runs across the tv screen with cable on not with DVD

Unplug,replug the cable box and the tv about an hour.The tv will reset itself,back to factory setting.The cable box should reboot itself and upgrade it softwares.The tv should work again.

The screen goes black on my lcd but the voulme

Usually a bad AV, Componet or HDMI cable from cable box to TV.

If DVD player or game system works with no issues the Tv is not at fault. (Usually)

If not TV needs service.

Problem is probably with your cable box as you have confirmed that the set is working by using the dvd player, that is unless you have a bad cable for the cable box.
