【Junk】AMD Ryzen 5 5600X No Video Output (Power Confirmed)

I purchased this item recently on another flea market site as a used item described as tested and working.
I installed it in my system, but I was unable to confirm video output, so I am listing it for sale.
​[Current Condition]
​Operation: Power to the motherboard was confirmed, the CPU fan spins, and background startup was confirmed, but no image (BIOS) is displayed.
​Pin Condition: As shown in the photos, to the best of my amateur observation, there are no bent or broken pins, and it fits smoothly into the socket.
​Exterior: There are grease marks on the heat spreader and scuffs from use.
​I cannot determine whether the cause is incompatibility with my components (motherboard, BIOS version, etc.) or a CPU failure. As I cannot perform further testing, I am listing this item as **junk.**
​[Notes]
​This is a **junk item (treated as defective).**
​No operation guarantee whatsoever. Please refrain from returns, refunds, or complaints.
​Only purchase if you intend to attempt repairs, or for research or parts harvesting purposes.
​I will take anti-static precautions and pack it securely to prevent damage during shipping.
