Does anyone have a schematic for connecting a DVD recorder to record shows from a tivo? I'm trying to connect a pioneer dvd recorder to record shows from my series 2 tivo, but I can't figure it out & the schematic from the dvd manual isn't real helpful. The dvd & my tv both have front inputs, if there are any shortcuts using those. If anyone has a schematic, to go along with any written directions, that would be helpful. Also, my tivo is already connected to my cable box & another dvd player, so if I can connect the dvd recorder without having to change too much or any of those existing connections, that would great

How do I replace the flyback on a RCA D52W14 rear projection TV? I have electrical and soldering knowledge, plus I already have the part. I just can't find any schematics online.

Need help fixing my Projection tv? I have a Sony projection tv KP-48V75. My son hit the screen and now there is a double image with shadows of green and purple. You can hit the back of TV and it would be straight again but it always goes back to the distorted picture. The menu is distorted too, doubled lettering. We adjusted the convergence which helps but it pretty much stays distorted. Anyone know what the problem is and what I can do to fix it. If I had the schematics of the inside of TV with what to do I can try to fix it myself. I called a TV repair place and they are wanting $115 to point me in the right direction Forgot to mention that the picture looks curved in on the top and bottom, the curve is solid purple
