Common Symptoms:

• Console powers on but no video output
• No audio output
• TV or monitor displays "No Signal"
• Console's light remains green but screen stays black
• HDMI or AV cables are properly connected but no display

Solutions:

1. Check and Reset Video Output Settings:
   • Hold down the power button for about 10 seconds until you hear a second beep, resetting the video output settings to default.
2. Replace HDMI/AV Cables:
   • Try using new or different HDMI or AV cables to ensure the issue isn't caused by faulty cables.
3. Clean HDMI/AV Ports:
   • Clean the HDMI and AV ports on both the console and TV/monitor to ensure proper connection.
4. Test with Different TV/Monitor:
   • Connect the PS3 to a different TV or monitor to rule out display issues.
5. Check and Reseat Internal Connections:
   • Disassemble the console and ensure all internal connections, such as the HDMI port and internal video cables, are secure and properly seated.
6. Replace the GPU/CPU Thermal Paste:
   • Overheating can cause no display issues. Replacing the thermal paste on the GPU and CPU can improve heat management.
7. Reflow/Reball GPU:
   • Reflowing or reballing the GPU can re-establish proper connections if the solder joints have cracked or become loose.
8. Replace Faulty Components:
   • Identify and replace any faulty components on the motherboard or video output circuitry that might be causing the issue.
