Thanks for the replies....
The KX155A/165A display is now over $715.00. YIKES.
Labor isn't too bad at around $120.00
Not sure where to go with this but to the bank with a big sack...:(
1999 Cessna 172S
Came out to find the display partially out then suddenly in-op but the radio seemed to worked for a bit... then nothing.
Local shop says it is a common failure on these radios.
The FBO had says their 172R did the same and they had to replace the radio.
I am an old school...
