help to debug thermometer circuit
ICL7107 datasheet here

Bigger and well focused photos will help.
 Having left and right not reversed will help. 

Some solder joints look "blobby". They should be shiny (if lead based solder isused) and flow smoothly onto pads.

Set meter to continuuty or "beeper" mode if available.
 Otherwise use lowest ohms range.
 Check for shorts between all adjacent (side by side ) pins with meter.
 Any that are joined - check if they are meant to be.

IC's in correct orientation?

All diodes and capacitors with correct polarity?  

What is small TO92 pg device at bottom of picture slightly off centre to left?
