Hey haven't been around in a while but have a quest about my LCD monitor hope this is the right place or someonen can help. I bought a monitor a while ago and about 8 months after getting it it started turning off. The power light was still on but the display goes black. I turn it off and then back on and it will work for a bit....never more then 20 minutes usually only about 2 minutes. What could be the cause of this and is it fixable or do i need to just tup and buy a new monitor...which i dont have money to do haah.
