1995 subaru legacy speedo not working my fix

[gros ventre]

ok so i purchased a 1995 legacy for 500 bucks from a friend that he was sick of dumping money in he spend an obscene amount of cash anyway the speedometer did not work and the shop kept changing sensors  after i spent time on forums and this particular forum i was able to bug out the issue so i thought i would share my process as to help others 

beginning with a generic scan tool  i received code P0500 and after some research it led me to speed sensors and how to test with a multimeter they seemed to work properly then i decided to buy a much better code reader and it gave me one specific word that changed my direction of solving this issue it stated fault on sensor "A" circuit that one word told me it was not a sensor so i decided that it was losing signal to the speedo i connected to the plug in the dash and the one at the sensor and determined that the wires were in fact good then i connected the sensor and connected it to a drill and found that it was sending the signal and it narrowed my search to the actual speedometer i took out apart the speedo and found a burnt board pictures below hope this helps someone else solve there issue. i purchased a used speedo from shopearl for 65 bucks also sorry i work with my hand i am not good at typing so please forgive my punctuation or lack there of
