Toshiba satellite no signal to external monitor

[mixalpix]

External monitor stopped working for Toshiba laptop. Monitor is working. But it seems that I'm having trouble properly booting and rebooting laptop to get signal to monitor. 2 orange lights on front when ac adapter installed. Monitor just has black screen. I played with it before turning off and on and was able to get it to work, but not now. Any help.
