Hello,

What is the best starting point to resolve the black lines?

Sorry, Not sure how to post Pict. on this site.

The screen will be perfectly clear at times and then black lines appear again. My kids jumping around causes the screen to bounce then clear up or back to picture with blk lines. Happy to send picture if I knew how. Thank you.[/img]

TV will not turn on. Did the black horizontal lines indicate a particular area on the power supply board?

I'd suspect vertical IC or convergence IC's.
