Trip Computer/SRS Indicator Acting Up

[rootin'teuton]

Greetings, fellow members!

I have a 98 ML320 w/c has just passed the 70,000 mile mark.
Would appreciate advice on what could possibly be causing the overhead trip computer not to function at random times. The little screen is completely blank. It has become hit or miss. My wife and I in fact have fun betting on whether the thing will come on or not every time we start the truck.

A by-product of this malfunction is that the SRS indicator on the dash does not light up with the rest of the idiot lights when in ignition mode and the Bose receiver stays on even after the vehicle is shut off

Yet at times, when we start the truck, everything comes on and works perfectly!

I checked the fuses and they're all fine. Could it be a faulty relay?

I'm hoping it's just a loose electrical connection but it sounds more that that.

Any advice would be much appreciated. Thanks in advance.
