Grant XL...dead

I have a Grant XL (Philly) and it is DEAD. The green light, lights up, but no channel indicator....nothing. D44 is toast. I used to run a CB shop 20 years ago...but that was a long time ago, and I no longer have any equipment. Does anyone have any ideas as to the cause of this particular diode to toast out? I don't want to get rid of this radio..always been great. I've considered buying another one...but shoot....by the time I shell out the money for that...this one could have been fixed.
At any rate...any ideas?
Worse case scenario......a GOOD shop recommendation would be appreciated.

Thanks for the input...
Fuse doesn't blow......and radio does receive some power. I am thinking the 8-volt side of the regulator took a crap. I've found some parts I need...but not all...so I found a shop that will fix me up for about 40 bucks. I think I'm going that route....at least they have the equipment to see what is causing the short.

 

What kind of price?

 

.....I'm looking at dodgem250's shop.
