Sony KP-51WS500 repair help

[adundee]

I recently came into possetion of this set. My fathers neighbor offered it to him for free, as it was broken. Unwilling to fix it, he gave it to me. The person he got the tv from was quoted $300 to fix it, I would rather fix it myself if its somthing I can do. So I get the tv home, plug it in, and surpisingly I do see a picture, however there was about a 2" black bar at the bottom of the picture, and it looked as if there was a blue transparency laid ontop of it. As I mess around with it, the blue "transparency" gets more and more solid. Eventually it turned to a completly blue screen, with white arched lines running horizontaly. It also developed some sort of static look to it. Oddly enough, my menus still look fairly normal...I dont know what that means. I took pictures hoping it would help, and knowing it would be rather hard to acuratly describe how it looked. Thank you for any help you can offer.

I was able to turn down the blue knob on the focus block and now have picture. I still have pretty bad retrace lines that are horizontal and wavy, and the black bar at the bottom of the screen. Im not quite sure what this indicates but I thought it may help.
