Home/TV Repairs/TV Power Supply Board Repair
TV Repairs
The power supply is the hardest-working board in your television and the first casualty of Gauteng's unstable mains. Component-level PSU repair is where our workshop earns its keep.
The details
Every volt your television uses passes through its power supply board, which converts raw mains into the clean, regulated rails the backlight, mainboard and panel require. It absorbs every surge, brownout and switch-on spike the grid delivers, and in Gauteng that is a serious workload. Load-shedding has multiplied PSU failures in our workshop because each restoration of power sends a voltage spike through the neighbourhood, and televisions left plugged in take that hit dozens of times a month.
The encouraging news is that power supply boards fail in predictable, repairable ways. Electrolytic capacitors swell and lose capacity, visible as domed tops on inspection. Rectifier diodes and MOSFETs short under surge stress. Fuses do their sacrificial duty. Falcon TV Repairs diagnoses these boards component by component, replaces what has failed with quality parts rated above the originals where the design allows, and load-tests every output rail before the board goes back into the set.
Component-level repair keeps costs down and turnaround short, since we are replacing parts rather than hunting scarce complete boards. Where a board genuinely is beyond saving, we source a tested replacement and say so in the fixed quote. Either route ends with a written workmanship guarantee and practical advice on protecting the repaired set from the next round of outages.
What we cover
The specifics, in plain language.
SYMPTOMS
A set that clicks but never starts, takes several attempts to power up, dies randomly during viewing, hums audibly, or went dark the moment power returned after load-shedding. Each pattern implicates the supply board.
CAPACITORS
Electrolytic capacitors dry out with heat and years, showing domed tops and leaking rings. They cause slow starts, restarts and ripple faults, and replacing the aged set of them rejuvenates many otherwise healthy televisions.
SURGES
The spike when power returns punches through rectifiers, varistors and switching transistors. We see the same pattern of blackened components weekly, and we repair it at component level rather than condemning the board.
TESTING
A PSU that measures fine unloaded can still collapse in use, so we test every output rail at realistic current with bench loads before declaring the repair complete. It is the difference between fixed and probably fixed.
UPGRADES
Where the layout allows, we fit capacitors with higher temperature ratings and semiconductors with more headroom than the cost-engineered originals, giving the repaired board a better chance against the next surge.
PROTECTION
We advise on worthwhile surge protection and the habit of unplugging during outages, honest guidance included with every job, because we would rather your set never needs us for the same fault twice.

FAQs
What people ask us before they book.
Send a photo of your dish, decoder or TV on WhatsApp. We can often tell you what's wrong before we get in the van.
WhatsApp a photoAlmost certainly not. The moment power returns, the grid delivers a spike that stresses every supply connected to it, and televisions in standby are connected. Failed rectifiers, varistors and fuses from restoration surges are the most common single fault category in our workshop. The repair is routine for us and usually very worthwhile on any reasonably modern set.
Usually, and often substantially. Component-level repair means paying for a handful of quality parts and skilled labour instead of a complete board that may be scarce for your model. Where a board is too far gone we say so and quote the replacement route instead. Either way you approve one fixed figure before any work happens.
Most power supply repairs move quickly because the components involved are standard parts we keep in stock. Sets collected same-day are frequently diagnosed the same evening, with the repair and load-testing completed over the following day or so. The fixed quote comes with a realistic return date for your particular model.
Diagnosis often starts on-site with rail measurements that confirm the supply is at fault. The actual repair involves desoldering and load-testing, which needs the bench, so we take the set in and return it finished. Collection and redelivery across Gauteng are handled by our own team as part of the job.
Not if we can help it. We fit replacement components with more headroom where the design allows, and we give straightforward advice on surge protectors worth buying and habits worth adopting during load-shedding. Combined with our written guarantee on the workmanship, the repaired board typically ends up more resilient than the factory original.
That symptom is a strong pointer to ageing capacitors on the supply board struggling to establish stable rails on the first try. It rarely improves on its own and usually progresses to a completely dead set. Repairing it early is sensible, and the fix generally involves inexpensive components, which the fixed quote will reflect.
