Why does my LCD screen flicker?

Episode 1147 (1:14:00)

Roger from Pasadena, CA
LCD monitor

Roger's LCD monitor is "flashing" after about a minute and then settles down and works again. Leo says that it may be a bad cable, which would be an easy fix. But it's more likely that the monitor is aging and the transformer or power supply is starting to fail, requiring it to "warm up" before use. It's not really worth fixing. Monitors are so cheap now, Roger should probably just get a new one.
