Black Bars and Power Issues

We just replaced the ICs in my Magnavox 51MP3964H/17, and when I turned on the tv, there were 2 thick black lines across the bottom half of the screen which only stayed on for a few seconds before the red power indicator light started blinking. Any ideas?

Sounds like a solder bridge bewtween the IC pins double check the solder for any pins accidentally bridged with solder.

Check the resistors around the amps. Many times one or more resistors are blown, but they may visually look fine.
Check all of the pico fuses.

Vertical black line on the screen of my 42" Magnavox flat panel lcd tv


I wish I could post a solution, but I don't have one. I too have a Magnavox. About 6 months ago, once every 2 weeks or so, the screen would just go black- all but an inch or two on either side. Now, it seems like it's a weekly thing, sometimes every hour or two. As of tonight, it has happened twice in a matter of thirty minutes. It usually repairs itself if I turn it on and then off again but that's just not working anymore. If anyone has a solution, let me know.
