I have a Toshiba tecra A2 that has a display problem. The display brakes up, it also does this on the a external moniter and the tv output.
I have been to replace the motherboard is this true?
It sounds like you have a graphics problem. Have you contacted Toshiba about the problem? If it's still under warranty they could fix it. It is possible to replace the motherboard if you can get another one. It's not easy though.
