How many miles until the Instrument Cluster Circuit Board starting malfunctioning?

I have 110,000 miles on my 1994 LS400 and only the gas gauge is slow to show the correct level.

 

I also have a 94' LS and mine started being slow on the fuel gauge possibly.. oh about 50K miles ago, so at 150K miles.

At around 195k miles the entire cluster started having time even lighting up.

 

My '94 LS400 had a little over 60K miles on it when the problems began. It doesn't get any better. I live in the SF Bay area (CA) where the weather's not extreme, and I may go days without seeing my speedometer. I have to make sure my gas tank's always at least 1/2 full because my gas gauge doesn't register either when the dash is out.

 

around 70k when it had problems lighting up. i don't even use my gas gauge n e more. it goes PAST empty. when i fill up to a full tank i think it goes up a bit and actually hits the "empty"
