Not familiar with the specific monitor but , sounds like it may be a "thermal" issue? ---may be try using a component cooler on the circuit? In general, the "no signal" message is triggered when there is no video synch detected &/or lost from the detection circuitry which can be inside of a signal process IC. Anything from a connection issue or malfunction in synch. processing can cause it. If you can find a schematic & scope the signal, should give you some ideas. |

There is a fault in your monitor- it could be anything- the point is that you are seeking a simple answer to a complicated question(as do many)- the bottom line is that experience & knowledge are needed to fix the fault- you don't have- find a good tv tech. |
