Indeed, so hook up your source and use it, let's see if it stays on longer with just the back cover off, if possible.

It went into sleep/standby mode due to no video signal detected. LCD_ON signal should also go away to turn off the backlight during sleep/standby mode.

I am picking up a thinner set of probes tomorrow and will post all the voltages in on state and shutdown state. And put all of the info together in one post to prevent the thread getting too bloated and confusing.

Update :

While I was waiting for a new set of thinner probes for my DM I decided to look at the back of the power supply board (see pic attached). As suggested by some of you guys earlier on I resoldered all the areas outlined in red. So far the monitor has been running for 4 hours without going into shutdown. Will run a longer test tomorrow and update if this has indeed solved the issue.

This was only possible because of you guys contributing to the thread with your wealth of experience.

I'd like to thank every single one of you guys who chimed in. This is a truly awesome forum and community. I'm amazed how some of you guys can look at some lowish resolution JPEG pics of the boards and diagnose whats going on.

Thank you guys.

I get lucky sometimes, fortunately you didn't have a complicated fault just bad joints.
