Plug [Q] tv screen turns off after unplugging MHL adapter

Hello, i have a problem with my mhl adapter causing my tv screen to switch off....
To get my phone appearing on the screen i have to connect the wires in a certain way for it to work.... Here is the order...
1. Put the tv on normal tv channels
2. Connect the mhl adapter to the hdmi cable
3. Turn the tv onto the HDMI source
4. Plug power cable into the adapter
5. Plug adapter into phone

Then the phone screen appears on the tv. But when i unplug the adapter from the phone, the tv screen will randomly turn off on its own, but the tv says it is on, by this i mean..
When my tv in on standby its led is red,
when the tv is on the led is green.
So after the mhl is unplugged for my phone, the tv screen turns off but the led on the tv is green as if the screen is on.
What is happening and how do i fix it?
