Hi I’ve had my VB for about 6 months now and when I bought it it worked fine. Now its starting to have those vertical lines fade in and out at random. I’m not very handy so taking the system apart makes me nervous as I don’t want to ruin the system. Plus I don’t have any type of bit to unscrew with. My questions is that I’ve heard somewhere that if you leave the system on for a while it will heat itself and then melt the wires back into place. Is this true at all or will that end up just damaging the system more?
