Hey everyone, crt noob here. I picked this up last week thinking I was getting a plug and play crt for movies and gaming. When I initially tried plugging anything into the composite I could get audio but no video. The remote that came with the tv is branded and it works to turn on and mute but otherwise it seemed useless. There are no indicators on screen no volume, no channel, no menu. All I got was static. 

I found a universal remote and programmed it. Now with the tv/vid button I can get the movie and sound to work. Volume works and the channel button takes it back to static. But there are still no indicators of volume or channel number and no menu will display. I looked up the service menu codes and when I input them it takes the screen from the movie to static but other than that I can’t tell if it’s doing anything. I’ve tried the buttons on the front and only some seem to work: power, volume down, and channel. I

The next problem is that the picture is dark, canted clockwise, and the right side shows some reflection during bright scenes. 

I have not been able to find much information on this tv online and even though I grew up with these tvs I have no idea how to adjust or work on them. 

My questions are 

1) are these problems diy fixable or is this thing a lost cause?  
2) Can I take the back off and peek inside without blowing myself up?
