Bearcat Display Problem
 

I have a Bearcat 8500 model receiver and the orange display quite working a
while back.
I decided to order four grain of wheat bulbs from Uniden and replaced the
old ones... still no lights.

I heard that there is a transistor controlling that circuit, does anyone
know where is it located on the board and what type it is, I would like to
solder one in and have my display back working.

Thanks
