Hi everyone,

I'm troubleshooting an Xbox 360 E (MFR Date: 2014-08-01, 9.6A Winchester board) and could use some expert advice.

The Situation:

Power: Solid green light on the power button. PSU light turns green when on.

Video: No output via HDMI. Tested on multiple screens/cables. (I do not have an AV cable to test).

Sync: Controllers (USB and wireless) flash indefinitely and never sync.

Mechanical: Disc tray ejects/closes perfectly.

History: Looks like the console was previously opened by a past owner.

What I've Done:

HDD: Removed a faulty internal HDD that was causing a short (orange light on PSU). Now it powers on but with no video.

Reset: Tried Y + RT display reset—no response.

The console isn't throwing a Red Dot, but it seems stuck in a boot loop or pre-BIOS stage. Since it was opened before, I suspect a botched repair or a failing component on the board.

Is this a known Winchester issue? I’m willing to buy Torx tools for a deep dive—should I focus on the RF module, HDMI encoder, or is this a likely CGPU failure?

Thanks!
