Does anyone have any tips to get the 3 color lines (Red, Green and Blue) to converge?

Maybe, there’s a reason you paid $20 for it.
See if any repair places will take it in.

Get the model number from your tv and do a google search for that problem. If it was sold at a garage sale for $20, it’s probably seriously damaged and will cost a lot to repair.

@asmonet Yeah, you get what you pay for! It’s really not worth fixing…we’re just going to put it upstairs for the kids to play their video games on, and who cares what the video games look like?!

@The Compassionate Heretic It’s not too bad actually…it’s watchable. And I did google it—that’s where I came up with the owner’s manual. I was just wondering if anyone had any secrets to share with me, for free! :)
