Screen goes Dark + Replaced Inverter and Backlight Already

The screen on my laptop would sometimes go dark and I could see the ghost images. It was happening for a couple of months. I was getting around this by switching to sleep mode and back which seemed to do the trick. Recently, the screen wouldn't light up at all, so for the moment I am using an external screen which worked. I did some research and the problem seemed to either be the inverter or the backlight. I replaced the inverter first which didn't seem to make any difference, then I replaced the backlight. It sometimes works and other times does not, switching to sleep mode and back seems to work now. However I'm sure it will stop working again. I'm thinking now it could be the inverter cables. Is it worth the hassle to replace this aswell? It would nearly have been cheaper to replace the whole screen at this point. Whats your advice?

I would Definitely replace the inverter cables before doing anything else, but first check their connections to the board and the logic board.
