Hello Everyone, I have an issue with my Sony STR-AV310. I think I fried mine 
. I would plug in my Sony Turntable to the PHONO jacks along with the ground wire to the ground screw and it would play well. Sometimes the buzzing would gradually get louder until it got so loud that the protection circuit goes on and an orange "P" would light up on the LCD. After I unplug the turntable, it goes back to normal. The last time I plugged it in, the buzzing got louder again until I heard a pop from the speakers. The receiver froze and it would not respond to the power button. Both the DBFB and Mute light was on and the LCD which said PHONO showed only parts of the letters lit. The "P" symbol didn't light. After a few seconds I saw a small amount of "Magic Smoke" coming from the receiver top. 
I quickly unplugged it after. I opened the top cover and looked for "fried" components. I didn't find any capacitors or resistors burnt or other burn marks on the PCB. The fuses near the transformer weren't blown. However I found the leads on what appears to be a Table Rectifier Diode burnt/charred. What I realized after is that the RCA plugs on the turntable seem to be frayed as when I plugged them into my computer, I also heard buzzing and crackling which was the same as I heard on the receiver before it broke. Is this receiver now completely broken? I have not plugged it back in because I am afraid I will damage it more. What I believe is that the shorted cables from the turntable caused too much power to be drawn from the rectifier and made it burn.
If I replace that table rectifier diode will it work again? I have found similar table rectifier diodes online rated at 8A and 400V. Based on a spec sheet I found online, the Bridge Rectifier on the receiver is rated at 200V 4A. Can I replace the old bridge rectifier with the 8A 400V rated one?
Here is where the broken part is:
This is how the replacement part should look like:
