Wavetek Meterman 27xt not working

I used this meter for many years with no Problems than one day it just stopped working
I am not getting any measurement When I touch the leads on the resistance scale or any other scale for That Matter
It's like there is no connection from the leads to the meter
I took it apart but I do not see anything Obvious on the board
The contact area looks Somewhat worn out but Even so it Should show something Even if it's not accurate

I Measured the fuses with another meter and they'll are not blown and bottom Measured the leads up to the back of the pcb and they'll have continuity
Is there anything else I can find out WHERE to measure the problem in May?
