Sony VAIO E Series (VPCEJ15FG) notebook

I've had my vaio for just under a year now and have had to have the keyboard replaced becuase a key broke. The tech said this was a common problem. I just recently had the screen replaced becuase there was a section on the right side of my screen that would get this strip of colored lines. Sometimes it would be a steady color and other times it would flicker through the screen. After my screen was replaced I went to try and use my Vaio and it wouldn't stay powered on. I don't know if the tech broke something in trying to replace my screen or if its a completely different problem altogether but after calling sony yet again..they are making me send my laptop in to be repaired. It has been a nightmare. And what's worse is that my factory warranty is about to expire. I dont know if I can continue with all these problems. I might wait till its fixed and try to trade it in to cut my losses now. My suggestion if you HAVE to get a vaio is to make sure you buy that extended warranty!! You WILL need it! Trust me.
