I have a chassis that keeps blowing resistor at location R456 (Metal film resistor .39ohm, 1/2 Watt, +/-5%). Has anyone come across this issue before? The chassis looks in mint condition.

Any help is appreciated. Thanks
 
?

What other parts are tie to it?
you using the schematic?
i got one but its hard to read the part location.
if you need it pm me and i will send it over.

did you read the ohms to ground on both sides of resistor
is it low?
