Chosen Solution
When I turn on my TV a blue box appears and says dmspc power save mode
This can have multiple solutions so heres a few: The graphics port went bad, try hooking to a monitor known to work **If the port is bad most desktops have several options for PCI slots to install a new graphics card The input on the monitor is wrong , for example if you’re connecting HDMI bur the monitor is on VGAThe power supply or other internal component could be bad I would first try hooking it up to a 2nd monitor/TV.
try checking the computer and seeing if it iis awake or if the monitor is connected to the right port.
