|No, I didn't mean it would "permanently" clear the problem but just help you get a better handle on whereabouts the trouble was. If you can beg or borrow a cable and that doesn't cause issues when the cable is waggled then most likely the problem is solved. |
There is also the possibility of a bad pin in the monitor socket, or even a faulty soldered joint behind behind it in the monitor.
Always pop back and let us know the outcome - thanks
