Weird dashboard problem

This morning as soon as I started the car, the speedometer dash turned completely scrambled and the rest of the lights keep blinking/flashing. The car does turn on and drive. Upon drive the Maint Reqd and Low temp icons keep flashing. I think I smell something burning as well but I not sure.
I have seen threads describe the dead dash but cannot find one with similar problem. In the video below you can see the scrambling. Ocassionally it will just turn off. I tried the battery disconnect but did not help. I definitely think something is burning around dash but cannot be sure.

 

I checked the threads but none describe scramble or burnt smell. I too think that is it but scramble is weird and the intermittent flashing of Maint req and low temp is also throwing me off.

In terms of age, the 12 volt may be old but I checked voltage from MFD and it was 12.4 at rest and 12 at ACC

 

It has ~160K miles.

 

I Know it has worked great so far except for needing the 3-way coolant controller change last year. No codes thrown at all.
Unfortunately, it is 2005 Prius and beyond the 9-year extended warranty time.

 

That's what I trying to figure out before sending it for repair as some other suggested. The other odd feature is the blinking freezing temp light or even headlights if I turn it on

 

An update on the situation. It turns out that the instrument combo meter did burn out. I have attached a couple of pics of the burnt out sites. It is square chip on the left of the front image and a another small area if you look closely at the back. I have ordered a replacement meter from ebay with close enough speedometer reading. I am hoping it was just the meter and not something else that caused it to burn out.
