This PlayStation 5 Nagashock custom controller came in with an L1 button that could not be pressed. Diagnostic testing found a faulty L1 microswitch.

We carefully opened the controller, working around the UV-mask-secured custom wiring and existing modifications, replaced the defective L1 microswitch, and reassembled it with the existing wiring preserved.

Post-repair testing confirmed L1 registered consistently, with proper mechanical response.

A button that stops responding is not always a board fault. Diagnostics first can show whether the switch itself is the problem. OHMX Repair Lab, Barrhaven, Ottawa.

This GameCube could read discs, but only after about 20 minutes warming up.

We reproduced the cold-start fault and replaced all 10 electrolytic capacitors on the optical-drive board. After several days powered off, it read discs on the first attempt in three separate cold-start tests, followed by five additional successful reads.

No laser adjustment was made. We checked the repair against the same conditions that caused the original failure.

A PS5 came in with no normal startup behavior. There was no beep or status light. The fan spun briefly, sounded like it was contacting something, then the console shut down.

Inspection found evidence of an earlier HDMI port repair, liquid metal spread around the APU retention area, and a torn 50-pin flex connecting the main board to the front power/status light board. The connector’s retention tab was also missing.

We replaced the damaged HDMI port at board level using microsoldering and installed a new 50-pin flex. After the repair, we checked connector seating and tested the power button and status light assembly.

Final testing confirmed video and audio output, Wi-Fi and wired network, Bluetooth controller pairing, and disc drive read. The console also ran under load with no faults observed during that test.

The controller arrived with a customer report that the right trigger was sticking, causing repeat presses and incomplete releases. Arrival condition was documented with photos.

During disassembly we found the L2 (left trigger) support post partially displaced. The support post is the small peg that locates and supports the trigger assembly. That displacement explained the intermittent sticking, incomplete release, and erratic trigger behavior even though the customer had flagged the right trigger.

We reseated the displaced support post into its proper position during the Standard Diagnostic. No replacement parts or additional repairs were required.

After reassembly we manually actuated the trigger repeatedly to verify mechanical movement and return. Post-test observation: the L2 trigger moves freely, returns correctly, and no longer exhibits the previously reported sticking or binding. Diagnostic outcome recorded as: no repair needed after testing.

The console arrived powering on but producing no HDMI video to the TV. We documented the arrival condition with photos and began a visual diagnosis.

Disassembly revealed a physically damaged HDMI port and severe dust and adhered residue throughout the cooling system fan, heatsink and ventilation channels. The motherboard was inspected after port removal and showed no additional visible physical damage. We noted that additional electrical faults could not be ruled out prior to replacing the HDMI port and completing functional testing.

We removed the damaged HDMI port, inspected the HDMI pads, PCB traces and surrounding components, and installed a replacement port. A comprehensive thermal service was completed with a deep clean of the fan, heatsink and vents and fresh thermal paste applied during reassembly.

After reassembly we verified successful power-on and restored HDMI video and audio output. Post-repair verification recorded PASS. Gaming load and thermal stability tests passed with no crashes, unexpected shutdowns, signal loss or abnormal fan behavior.

The customer brought a desktop that would boot to Windows but then suddenly shut down after several minutes and restarted while launching a game. During a diagnostic session we reproduced the instability and saw an unexpected shutdown that produced Event Viewer entries (Kernel‑Power Event 41 and EventLog 6008). After the restart the display showed brief instability and an HDMI signal loss.

BIOS-level monitoring showed stable CPU and motherboard temperatures and ATX rail voltages for more than 35 minutes, so we ran memory diagnostics next. MemTest86, which checks RAM for read/write errors, produced multiple errors when all four 16 GB DDR4 modules were tested together. Isolating modules revealed DIMM 1 failed on two separate tests while DIMM 2, 3 and 4 passed.

We removed the defective DIMM and validated the system with two verified-good 16 GB modules installed in A2/B2 for 32 GB dual-channel operation. A 15‑minute CPU stress test, a 15‑minute GPU stress test (no artifacts or signal loss), combined CPU/GPU power testing, five consecutive Windows restarts, and an overnight cold-start check all completed with no further hardware faults reproduced.

Removing the failed memory module eliminated the reproduced shutdowns during our validation and restored stable boot and gaming behavior under the tests we recorded. Diagnostics first. Parts second.

Customer reported games closing abruptly and, less frequently, full console shutdowns during gameplay. We ran an extended diagnostic session of about five hours. During that testing the console did not fully power off, but the reported symptom reproduced once when a running title closed to the dashboard.

Internal inspection showed heavy dust, pet hair and debris restricting airflow. Measured internal temperature during testing was about 60°C and existing thermal putty was in poor condition.

We completed a full thermal service and heavy debris cleaning. Old thermal putty was removed and replaced, and the APU thermal paste was cleaned off and refreshed with Arctic MX-4. Four missing internal screws were replaced.

We also found evidence of a prior HDMI repair with significant residual flux. The HDMI port was functional and excess flux was thoroughly cleaned before reassembly. Post-service testing used the customer title NHL 27; the session ran without crashes, dashboard returns, or shutdowns during the completed test periods.

The owner reported the PS5 was overheating and shutting off. On arrival we found heavy dust throughout the console, with ventilation grilles and airflow paths compacted and restricting airflow.

These findings were consistent with a thermal-management issue that could contribute to the reported overheating and shutdowns. We also noted minor pitting on one corner of the heatsink contact surface; the pitting was judged superficial and not severe enough to require heatsink replacement at this time.

We completed a PS5 Thermal Service. Existing liquid metal was removed and fresh liquid metal was applied to the APU/heatsink contact surfaces. We re-inspected the heatsink and recorded no visible exposure or damage to the v***r chamber before reassembly.

After reassembly we ran final functional and thermal testing, including approximately 30 minutes of sustained gaming (Madden NFL 27). The system remained stable with normal fan operation and no overheating, unexpected shutdowns, or abnormal behavior. Thermal imaging showed stable thermal behavior, and HDMI, controller, disc drive, network and general functions tested normally.

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.
