PS5 HDMI repair in Ottawa.

This PS5 came in with a loose HDMI connection.

The console powered on, but the HDMI cable would not sit properly. If the cable was held tightly in place, signal would appear on the screen. Different cables, TVs, and monitors had already been tried before the console came in.

That kind of symptom usually points to a physical connection problem at the HDMI port, not a settings issue.

Once inspected, the HDMI pins were no longer making proper contact with the board.

The damaged HDMI port was removed and replaced using board-level microsoldering. The connector area was inspected before reassembly to make sure the pins were seated correctly and the surrounding area was clean.

Fresh liquid metal was also applied while the console was open.

After reassembly, the PS5 was tested and confirmed working properly. Network, Bluetooth, and disc drive operation were also checked before return.

A loose HDMI port is not something to keep forcing.

The more the cable is pushed, pulled, or angled to “make it work,” the higher the chance of damaging the port, pads, or surrounding board area.

HDMI repaired.
Signal restored.
System functions tested.

DualSense PS5 controller stick drift repair in Ottawa.

Two PS5 DualSense controllers came in with stick drift.

The white controller had drift on the left stick.
The cosmic red controller had drift on the right stick.

Instead of replacing only the failing stick on each controller, both controllers were upgraded with new TMR sticks on both sides.

That matters.

On a controller that already has drift on one side, the other original stick may still be working today, but it has the same wear-prone design. Upgrading both sticks gives the controller a more balanced long-term repair instead of only fixing the side that has already failed.

Both controllers were opened, the original analog stick modules were removed, and TMR sticks were installed.

After the repair, each controller was tested for input response, centering, range, and linearity.

Stick drift repaired.
Both sticks upgraded.
Linearity tested.

Custom mechanical keyboard diagnostic and connector repair in Ottawa.

This Aeris Studio Killer65 came in completely dead.

No lights. No key response. The computer would not recognize it. The customer had already tried a different cable and a different computer with no change.

Initial bench testing showed 0 mA current draw, which pointed to a power delivery issue rather than a normal USB detection problem.

This was a custom-built mechanical keyboard kit, and no manufacturer build guide was available, so the diagnostic had to be done properly: USB-C power verification, continuity and resistance testing, isolation testing between the daughterboard and mainboard, and microscope inspection of the internal connector path.

Once the case was opened, the issue started to make sense.

The internal daughterboard-to-mainboard JST cable was disconnected, several mounting screws were loose, and one screw had been installed in the wrong location.

The cable was also short for the case depth, creating tension at the connector. That kind of mechanical stress can cause an intermittent connection that works for a while, then suddenly fails.

The repair did not require replacing parts.

The connector was reseated, the incorrect screw was removed, the loose mounting hardware was addressed, and strain relief was added near the connector so cable tension is absorbed by the anchor point instead of the connector contacts.

After reassembly, the keyboard was recognized by the PC, the LEDs came back, and key input was restored.

The keyboard was then verified stable under extended real-use testing with the case fully closed.

This was not a parts-swap repair.

It was measurement, isolation, mechanical inspection, connector repair, strain relief, reassembly, and validation.

Diagnostics first. Parts second.

Xbox Series X HDMI repair in Ottawa.

This Xbox Series X came in with no signal caused by a damaged HDMI port.

The damaged port was removed and replaced using board-level microsoldering. Before reassembly, the HDMI pads and surrounding circuitry were inspected under magnification, and the repair area was cleaned properly.

That part matters.

A working HDMI repair is not just about getting an image back once. The connector needs to be aligned correctly, the pins need proper contact, and the surrounding area needs to be inspected before the console goes back together.

After the repair, the console was tested and confirmed outputting video at 4K resolution.

Wi-Fi, Bluetooth, and disc drive operation were also checked before return.

HDMI replaced.
4K video confirmed.
System functions tested.

PS5 thermal service and heavy contamination removal in Ottawa.

This PS5 came in shutting down during gameplay. After it shut down, the client had to unplug it from AC before it would restart.

Once the console was opened, the contamination level was heavy.

The top intake, fan shroud, fan blades, and heatsink airflow path were packed with matted fibre and lint. This was not loose dust that could be cleared properly with compressed air from the outside.

The fan had to be removed, and the contamination had to be manually extracted from the intake area, fan assembly, and heatsink fin stack.

That matters.

When airflow is blocked this heavily, the console can lose its ability to move heat out of the system under load. On a PS5, that can show up as overheating, shutdowns during gameplay, or unstable thermal behaviour.

The console received a full thermal service while it was open. The heatsink was removed, the cold plate and APU die were cleaned, fresh liquid metal was applied, the airflow path was cleared, and the thermal pads were inspected.

This was not just a quick fan cleaning.

It was full teardown, manual contamination removal, liquid metal service, and thermal validation before return.

Final testing included sustained load testing and thermal camera verification to confirm the console remained stable after service.

Heavy contamination removed.
Airflow restored.
Fresh liquid metal applied.
Thermals verified under load.

Ubiquiti UniFi Dream Machine Pro liquid damage assessment in Ottawa.

This UDM Pro came in after basement water damage. The client needed to know whether the failure was related to the water exposure, whether the unit was repairable, and needed a written diagnostic report for an insurance claim.

The unit was not powered on during assessment.

That matters.

When a device has confirmed water exposure, especially around the power input or power supply, turning it on “just to see what happens” can create more damage or become a safety risk.

The inspection started from the outside in. Water ingress was traced through the IEC power connector area, where corrosion patterns matched the path of entry.

Once opened, the power supply board showed corrosion-driven failure. One component was destroyed/absent, another tested open circuit, and the board substrate showed scorching around the damaged area.

That power supply board was not economically repairable.

The main logic board was then removed and inspected separately on both sides under the microscope. No corrosion or conductive damage was found on the main board during inspection.

That changed the conclusion.

This was not a case where the entire unit was automatically considered destroyed. The failure was isolated to the power supply section, while the main logic board remained clean based on visual and microscope inspection.

The unit was reassembled with the damaged power supply disconnected from the main board as a safety precaution. No functional power-on test was performed because the damaged PSU was not safe to energize.

The client received a written diagnostic report with photo documentation, failure explanation, and repair/replacement pathway information for the insurance claim.

Liquid damage diagnostics are not about guessing.

You trace the entry point.
You document the damage.
You isolate the failed section.
You avoid unnecessary risk.
Then you give the client a clear written answer.

PS5 Slim thermal service in Ottawa.

This PS5 Slim came in with overheating issues.

Once it was opened, the problem was not just one thing. Airflow was being restricted, the liquid metal showed oxidation, and the heatsink contact area had existing pitting.

The pitting was documented and explained to the customer, but it was not severe enough to justify replacing the heatsink assembly at this stage.

That matters.

A proper thermal service is not just opening the console and adding new liquid metal. The cooling path needs to be inspected, the heatsink surface needs to be checked, and any existing damage needs to be documented before the console goes back together.

The service included cleaning the cooling path, removing the old liquid metal, preparing the APU contact area, and applying fresh liquid metal properly.

After reassembly, the console went through functionality testing, including disc drive, network, Bluetooth, fan behavior, and temperatures under load.

The PS5 was tested under load for 30 minutes with stable temperatures between 60–70°C and no overheating issues.

Airflow restored.
Fresh liquid metal applied.
Existing heatsink pitting documented.
Thermals verified under load.

PS5 fan connector board repair in Ottawa.

This PS5 came in after the fan connector was torn off the motherboard during a cleaning attempt.

The connector had not simply come loose. Under the microscope, it was clear that the connector had been physically pulled off the board, taking pads with it.

A previous repair attempt had also reheated and scraped the area. That left one pad completely gone, burned solder mask, and an internal ground layer exposed at the surface where it should not have been.

That matters.

Installing a new connector directly over damaged material and exposed ground is how you create a repair that works today and fails later.

Before quoting the repair, the connector was mapped against the boardview to confirm whether the missing lines could actually be rebuilt. The fan connector has five positions: three grounds, one 12V supply line, and one PWM control line.

The PWM line is important. A PS5 fan does not just need voltage. It also needs the control signal that tells the fan how to operate. Without that line, the fan can still stay dead even if 12V is present.

Both missing lines had accessible anchor points, so the repair was viable.

The damaged material was removed down to clean substrate. The exposed ground layer was insulated with UV solder mask. A new fan connector was installed, the missing 12V and PWM lines were rebuilt, and the connector body was mechanically anchored to the surrounding board so it was not relying on destroyed pads to hold it in place.

That mechanical part matters as much as the soldering.

With the original pads gone, the connector cannot be treated like a normal replacement. It has to be rebuilt and reinforced as a damaged-board repair.

The console was first tested with a known good reference fan to confirm the board was driving the connector correctly. After that, it was tested again with the customer’s original fan, which confirmed the fan itself was healthy.

No extra fan replacement was needed.

Fresh liquid metal was also applied as part of the procedure since the heatsink had already been removed.

Final assembly was completed, the fan operation was verified, and the console was returned with the repair limitations explained clearly.

This was not a simple connector swap.

It was pad damage, exposed internal layer, trace mapping, insulation, jumper reconstruction, mechanical reinforcement, and final validation.

Xbox Series X HDMI repair and thermal service in Ottawa.

This Xbox Series X came in with a damaged HDMI port and no proper video output.

Once it was opened, the HDMI port was not the only issue. The console also had heavy dust buildup obstructing the heatsink airflow.

That matters.

A console can get its HDMI port replaced and still come back later with overheating or shutdown problems if the cooling system is ignored while it is already open.

The damaged HDMI port was replaced, the connector area was cleaned, and the console received a thermal service with fresh MX4 thermal paste and thermal putty.

After reassembly, video output was restored and 4K was verified. The console was also tested under load, with temperatures staying around 55–60°C after 30 minutes.

This is why we inspect the full system, not just the obvious broken part.

HDMI repaired.
Airflow restored.
Thermals verified.
