LG TV 37LC45 goes black with slight flickering on top, sound working.

Usually it will work for a while until it goes black with the said flickering on top. Sound works and the image for a random amount of time. Any tip to fix it/ broken component(s)?

The first image its the tv working normally, the second when it goes black and the third an odd angle of the back of the tv.

FYI the image got better as I played around with the tv, before there were a lot of colored stripes and the image quality was awfull.

First: There are no pictures posted for this. Post them if you can.

Second: There are a number of reasons for a black screen. What is needed though, is whether or not there is still a picture on the screen when it goes black. Hold a flashlight close to the screen and see whether or not there is an image. Report the results here.

Since this happens on a random basis, it can indicate a failing component or even a bad connection somewhere. Open up the back and remove and reattach each cable. Sometimes this can resolve the problem. Take a few pictures of the boards and post them here as well. We may be able to identify a component that is failing from the picture.

Start with the re-seating of the cables and the flashlight test and update this. We will continue from there.
