Yes, most meters will be like this.

I wouldn't worry too much about the possibility of losing traces in the multilayer board here, the analogue stuff before the ADC should be reasonably straightforward. What might be slightly more tricky is the rotary switch; some of the traces from that might be quite sneaky, you might have to use one of the various "tricks" like a frayed test lead with your continuity tester to get broad coverage over a part of the board.

Don't give up hope, even if you have to put it to the back of a drawer occasionally. If you have some luck you might find a scrap one with a broken screen that can be used as a donor.

If the asic is solid then there is only one possibility, the MSP main IC is faulty.
Is the device still under warranty? Because the warranty of these devices is LLTW (limited lifetime warranty), you can get support from an authorized service.

I bought the meter second hand (even tho was brand new) so no documents came with it. I've called an authorized repair center in my country and they told me that without some receipt / invoice when and where I bought it, they can't take a look at it.

I'll leave it in a drawer and check on it again when I'll have more time, for now I'm aiming towards an 87-V.

Yeah, they will look to protect their bottom line. It would be nice if there was a service manual/schematic available. It's beyond my skills and patience to reverse engineer one.
