Xbox One FAT HDMI Port Replacement
Complete Soldering Guide to Replace a Damaged or Broken HDMI Port
A broken HDMI port is one of the most common hardware failures on the original Xbox One FAT (model 1540). Whether caused by a bent cable, accidental yanking, or repeated plugging and unplugging over years of use, the result is the same: no video output, flickering signal, or intermittent display dropouts. This repair requires soldering experience, but with the right tools and technique, a new HDMI port costs under $5 and takes about 45 minutes to install.

Open HDMI Diode Tester âWhat Causes HDMI Port Failure on Xbox One
The Xbox One FAT uses a standard Type-A HDMI connector soldered directly to the motherboard with 19 signal pins and 2 mounting tabs. Unlike DisplayPort connectors that have retention clips, HDMI relies entirely on friction to hold the cable in place. This makes the port vulnerable to lateral stress when cables are pulled at an angle.
đ§ Common HDMI Failure Modes
- Bent or broken pins inside the port (most common, caused by cable insertion at wrong angle)
- Cracked solder joints on mounting tabs (caused by cable yanking or console being moved with cable attached)
- Lifted PCB pads under signal pins (caused by excessive force or poor previous repair attempt)
- Damaged HDMI retimer chip (TDP158 on Xbox One S/X, not present on FAT model)
How to Confirm Your HDMI Port Needs Replacement
HDMI Failure Symptoms
- âNo video output at all (black screen, TV says 'No Signal')
- âVideo cuts in and out when HDMI cable is moved
- âPurple or green artifacts on screen
- âAudio works through HDMI but no video
- âConsole powers on normally (white light) but no display
- âHDMI cable sits loosely in the port or wiggles excessively
Before replacing the port, rule out cable and TV issues. Test with a known-good HDMI cable and a different TV input. If the problem persists across cables and displays, the port itself is the issue.

Before You Start: Important Warnings
â ī¸ Soldering Required
This repair involves soldering on a multi-layer PCB with fine-pitch pins. If you have never soldered before, practice on a junk board first. A botched HDMI replacement can lift pads, short signal traces, or damage the APU. If you are not confident in your soldering skills, take the console to a professional repair shop.
Step-by-Step HDMI Port Replacement
Xbox One FAT HDMI Port Replacement Procedure
Advanced repair requiring soldering station and hot air
Step 1: Disassemble the Console
Remove the side ventilation panel by prying it off carefully. Remove all T10 Torx screws from the rear panel and bottom. Separate the top and bottom shell halves. Disconnect the front panel ribbon cables and eject button connector. Remove the metal RF shield screws and lift the shield to expose the motherboard.
Step 2: Locate and Inspect the HDMI Port
The HDMI port is on the rear edge of the motherboard. Inspect the port under good lighting (a magnifying lamp helps). Look for bent pins, cracked solder joints on the mounting tabs, or any visible damage to the PCB pads around the port.
Step 3: Perform a Pre-Repair Diode Test
Set your multimeter to diode mode. Test each HDMI pin against ground. Record the values. This baseline tells you whether the problem is limited to the port or if the HDMI controller circuitry is also damaged. If all pin values read OL (open line) on the signal pins, the port is the only issue.
Step 4: Remove the Old HDMI Port
Apply flux to all solder joints. Using a hot air station at 380-400°C with medium airflow, heat the port evenly. Apply solder to the mounting tabs to increase thermal mass. Once the solder flows freely on all pins and tabs, gently lift the port straight up with tweezers. Do not rock or twist, as this can lift pads.
Step 5: Clean the PCB Pads
Once the old port is removed, clean all residual solder from the pads using solder wick and flux. The pads must be flat and clean for the new port to sit flush. Use IPA and a brush to remove all flux residue. Inspect each pad under magnification for lifted or damaged traces.
Step 6: Install the New HDMI Port
Align the new HDMI port on the pads. The port should sit perfectly flat with all pins centered on their pads. Solder the two large mounting tabs first to anchor the port in position. Then solder each signal pin individually, using thin solder wire (0.5mm) and flux. Work methodically from one end to the other.
Step 7: Inspect and Clean
Inspect every solder joint under magnification. Check for bridges between adjacent pins (most common error). If bridges exist, apply flux and drag a clean soldering iron tip across the bridged pins to separate them. Clean all flux residue with IPA.
Step 8: Post-Repair Diode Test
Repeat the diode test from Step 3. Compare values to your pre-repair baseline. All signal pins should show healthy diode readings. If any pin shows 0.000 (short to ground), you have a solder bridge that must be corrected before powering on.
How to Test If the Repair Worked
Post-Repair Verification
- Visual Inspection: All solder joints should be shiny and concave. No bridges between pins. Port sits flush with the PCB edge.
- Diode Test Pass: All HDMI pin diode values match expected readings for Xbox One FAT. No shorts to ground.
- Video Output Test: Reassemble enough to power on safely (connect power supply, controller). Connect HDMI cable to a TV. The Xbox One should display the boot animation. Test at 1080p and 4K (if applicable) to verify all signal lanes work.
- Cable Retention Test: The HDMI cable should click into the new port firmly. Wiggling the cable should not cause signal dropout.
How Long Will This Fix Last
A properly soldered HDMI port replacement is a permanent fix. The new port has fresh solder joints and undamaged pins, restoring the connection to factory-new condition. With normal use (not yanking cables or moving the console while connected), the replacement port should outlast the console itself.

Frequently Asked Questions
Q: Can I replace an Xbox One HDMI port without soldering?
No. The HDMI port is surface-mounted to the motherboard with 19 signal pins and 2 structural mounting tabs. There is no way to replace it without desoldering the old port and soldering a new one. Conductive adhesive or press-fit solutions do not exist for this component.
Q: How much does professional Xbox One HDMI repair cost?
Professional repair shops charge $60-120 for HDMI port replacement, including parts and labor. Mail-in services may charge additional shipping. Turn-around time is typically 1-5 business days. This is cost-effective compared to buying a replacement console if your soldering skills are limited.
Q: Can a damaged HDMI port damage my TV?
A physically damaged port (bent pins, broken housing) cannot damage your TV. A shorted HDMI port (where signal pins contact ground) could theoretically send incorrect voltage to the TV's HDMI input, but modern TVs have protection circuits against this. The risk is negligible.
Q: Is the Xbox One FAT HDMI port the same as the Xbox One S?
The physical HDMI port connector is the same standard Type-A form factor. The port itself is interchangeable. The difference is the Xbox One S and X have an additional HDMI retimer chip (TDP158) between the APU and the HDMI port. If the retimer chip fails on those models, replacing the port alone will not fix the issue.
Q: My Xbox One shows a green screen after HDMI repair. What went wrong?
A green screen after HDMI port replacement usually indicates a solder bridge between the TMDS data lanes. Remove the motherboard and inspect the HDMI pins under magnification. Apply flux and re-flow any suspicious joints. A single bridge between adjacent signal pins causes color channel corruption.
Xbox One FAT HDMI port replacement is a straightforward repair for anyone comfortable with soldering. The $5 part cost and 45-minute repair time make it one of the most cost-effective console fixes available.
