In September 2026 an Xbox Series X came into our Cambridge workshop with no picture. Its HDMI port had already been replaced by another repair shop about six months earlier, and the customer was sure the inside of the console was fine. It was not. This is what we found, what it took to repair it properly, and what to ask any repair shop before they touch your console.
Every photo in this post is from this one console.
An HDMI port that had already been “repaired”
The port had started to fail again. As most people do, the customer wiggled the cable to get a picture back, until one day there was no picture at all. He brought the console to us for a new port.
Once it was open, the story was different. The previous shop had soldered a new port onto the board, but had not repaired the damaged pads underneath it. It had not cleaned the console, and it had not replaced the thermal paste. The customer had not been told about any of this. He had collected a closed console and assumed the inside matched the outside.
What we found inside
- Torn pads and damaged tracks around the HDMI port. Some of the solder pads had come away from the board, and copper tracks under them were damaged. The second port had simply been soldered to what was left, which is why it did not last.
- The original thermal paste, dry and crumbling. Nobody had touched it.
- A heatsink blocked with dust. The console had never been cleaned, which is the first thing any proper console repair includes.
We sent the customer these photos before doing anything else and explained that this was now a motherboard repair, not a port swap. We also said what we always say about a board in this state: most can be saved, not all, and nobody can promise the result before the work is done.
Why wiggling a failing HDMI cable makes it worse
When a port starts to go, moving the cable can press a damaged contact back together for a moment and the picture returns. It feels like a fix. Every wiggle, though, puts force on the port and on the board under it. Over time that causes:
- cracked solder joints around the port,
- solder pads separating from the board,
- copper tracks breaking,
- damage to the small components next to the port,
- an intermittent connection that can heat up.
A port that only works with the cable held at an angle should come in straight away. Six months of wiggling turns a simple port replacement into the repair below.
The repair: six hours under the microscope
Our hardware specialist started the evening the console arrived and finished the next morning. In total it was about six hours of microscope work, roughly three times what a normal port replacement takes.
- Finding the tracks. The board was scraped back around the port to expose the copper tracks and trace every connection.
- Rebuilding the connections. The broken tracks were rebuilt with fine wire and new pads were bonded on top of them. The new port now sits on reinforced pads, a stronger anchor than the original pads alone.
- Fitting the new port. A new HDMI port was micro-soldered onto the rebuilt pads, every pin bonded and checked.
- The work the first repair skipped. Full deep clean, fresh MX-7 thermal paste on the processor, and reassembly.
- Testing. Picture through the new port, then the console ran on our bench before it went back to the customer the following morning.
What “rebuilding the tracks” actually means
The copper tracks that carry the HDMI signals across the board are about the width of a human hair, and they sit under a protective coating. When a pad tears off, the track behind it tears too. To rebuild one, the coating is scraped back under the microscope until clean copper shows, a hair-thin wire is laid along the track and soldered at both ends, the joint is sealed, and a new pad is built on top for the port to sit on. One slip and a neighbouring track is damaged. Done once, it takes minutes. Done for every damaged connection on an HDMI port, it takes the best part of a working day, which is why this repair took about six hours instead of two.
Like every repair we do, this one comes with a 12-month warranty. If anything is ever wrong, the console comes back to us in Cambridge or Dagenham.
What to ask before anyone touches your console
- Tell them about previous repairs. Had we known this port had been soldered before, we would have booked advanced diagnostics first and quoted on what we found.
- Ask for photos of the board under the port, before and after. A shop that works under a microscope has them.
- Ask whether cleaning and thermal paste are part of the job. A console that is open should never go back together dirty.
- Ask what happens if the pads are damaged. The honest answer is a track and pad rebuild, not a port soldered onto what is left.
- Ask about the warranty. Ours is 12 months.
Questions people ask us about Xbox HDMI repairs
Can an Xbox Series X HDMI port be repaired after a failed repair elsewhere?
Usually, yes. The damaged pads and tracks have to be rebuilt under the microscope before a new port can be fitted. We photograph the board and show you before we start, because a board in this state cannot be guaranteed in advance.
Why did the first repair fail after six months?
The port had been soldered onto damaged pads, so it had little to hold on to. Every plug and wiggle of the cable worked it loose again.
Is it bad to wiggle the HDMI cable?
Yes. It can bring the picture back for a moment, but it tears pads off the board and breaks tracks. Bring the console in as soon as the picture becomes unreliable.
Do you clean the console during an HDMI repair?
Yes. Every console we open gets a full clean, and the thermal paste is replaced when it needs it. On this Xbox the paste was the original, dried out, and the heatsink was blocked.
How long does an Xbox HDMI port repair take?
We order the port in for each Xbox, so allow a few days for delivery. The repair itself is normally three to four hours of work. This one took about six because of the track rebuild.
Is there a warranty?
Yes, 12 months on every repair, and you bring the console to us in Cambridge or Dagenham if anything is wrong.
