Power Supply Repair Service UK for AV Power, Processing & Distribution
A failed power supply, unstable processor or faulty distribution unit can take a much bigger part of an AV system offline than the box itself suggests. Complete Pixel Solutions diagnoses and repairs power supplies, receiving cards, processors and distribution equipment used across live-event AV systems. Our power supply repair service UK approach starts with finding where the fault actually sits, then repairing and testing the affected equipment before it goes back into service.
Our approach
Power Supply Repairs Done at Component Level, Not by Swapping Boards
Fault finding
Board-Level Fault Finding
A failed power unit does not always mean the whole assembly needs replacing. We investigate the electronics and identify the section responsible for the fault before recommending the repair.
Testing
Power Supply Testing
Power equipment can appear normal until it is operating as part of the wider system. After repair, we test each unit under conditions that match its equipment type and the original fault.
Processing
Processing and Receiving Cards
A display or AV system can show a symptom that starts further upstream. Receiving cards and processors are assessed alongside the surrounding system where required.
Report
Repair Report
Every completed repair comes back with a written report showing what was found and what work was carried out, giving you a useful record for your equipment inventory.
What we fix
- Switch mode power supplies for LED, lighting and audio equipment
- Receiving and sending cards
- Video processors and scalers
- Dimmers and power distribution units
- Cable testing, repair and certification
- Batch testing of spares so your backup stock actually works
Common symptoms
- Equipment dead on arrival at the gig
- Random resets and brownouts under load
- A spares shelf full of unknowns
- Cards swapped show to show without ever being tested
- Cables that fail intermittently and get repatched around
A dark display, a processor that will not start or a distribution unit that has stopped supplying equipment can have several possible causes. Each unit is assessed individually before any repair is recommended.
Our power supply repair process
What Happens When You Send a Power or Processing Fault
Power faults are not always obvious from the outside. A unit may be completely dead, drop out intermittently, reset during operation, or cause problems further along the system. Our process is built around tracing the fault to the affected power, processing or distribution section before repair work begins.
01
Tell Us About the Unit and Fault
Tell us the make and model, and describe what the equipment is doing. Let us know if it will not power up, cuts out, resets, shows unstable output or affects connected equipment. Photos, fault codes and a short video can also help us understand the problem before the unit arrives.
02
Assess the Fault and Confirm the Repair
Once the equipment is with us, we assess the relevant power supply, board, processing or distribution sections to identify where the fault sits. Where the unit is suitable for repair, we confirm the work required, cost and expected turnaround before proceeding.
03
Repair the Affected Section and Test It
We repair the faulty section at the level the equipment requires, whether that means a component, power supply board, processing board or another repairable part. The unit is then tested to check that the repair has resolved the original fault and that it is operating as expected.
04
Document the Repair and Return the Unit
Every repaired unit leaves with a written report covering the fault found and the work carried out. This gives you a clear record of the repair and helps with future servicing or equipment inventory before the unit goes back into use.
Questions we hear a lot
Is repair worth it on cheap parts?
Often yes at volume. Repairing a batch of power supplies or cards usually costs a fraction of replacement, and you get a tested, reported unit rather than an unknown.
Can you test our spares stock?
Yes. Send in the shelf of maybes and we return it sorted: passed, repaired or beyond economic repair, each unit labelled and reported.
Do you handle cabling?
Yes, testing, repair and end replacement across power, data and signal cabling used in live production.

Rental houses
Stock that is broken is stock that is not earning. We run repair loops for rental houses so damaged tiles and fixtures come back into the hire fleet instead of stacking up in a corner of the warehouse.

Have a Faulty Power Supply? Let's Get It Assessed
A failed power supply, processing unit, or distribution component can look like a much larger AV problem. Send us the make, model and symptoms, and we can assess where the fault actually sits.
If the equipment is suitable for repair, we'll confirm the work, cost and turnaround before anything starts. You get the repair and a written report back with the unit.
