Home/TV Repairs/TV Keeps Restarting or Boot Looping
TV Repairs
A television trapped in an endless cycle of logo, black screen, logo again has one of two illnesses: corrupted software or collapsing power. Telling them apart is the whole game.
The details
A restarting television is uniquely infuriating because it almost works. The logo appears, hope rises, the screen goes dark, and the cycle begins again, sometimes every few seconds, sometimes minutes apart. Underneath, two unrelated failure families produce this identical behaviour. In the first, the operating system is damaged and crashes partway through booting, forcing the restart. In the second, the power supply establishes its voltage rails, sags under the load of the boot process, collapses, and triggers a restart the moment it recovers.
Guessing wrongly between those two wastes money, which is why Falcon TV Repairs measures instead of guessing. Watching the supply rails on a scope during the boot cycle answers the question within minutes: rails that dip as the set loads point to tired capacitors or a failing regulator, while rock-steady rails through a restart put the blame on corrupted firmware or a failing storage chip. Only after that measurement do we prepare your fixed quote, aimed at the actual disease rather than the symptom.
Both cures are well within our daily work. Power-side boot loops respond to component-level PSU repair, and software-side loops to firmware recovery through USB or the service interface. Either way you receive a written guarantee on the workmanship and a set that boots once, properly, and stays on.
What we cover
The specifics, in plain language.
SYMPTOMS
Restarts every few seconds before the logo completes, cycles that only start once the set has warmed up, loops that began right after an update, or restarts that coincide with load-shedding recovery. Each detail steers the diagnosis.
POWER SIDE
Tired capacitors deliver enough voltage to start booting but sag when the backlight and processor load up, collapsing the rails and forcing a restart. We watch this happen on the scope, then rebuild the supply stage.
SOFTWARE SIDE
Corrupted firmware from a failed update or an ageing storage chip crashes the boot sequence at the same point every cycle. Recovery flashing through USB or the service port rebuilds the platform cleanly.
CLUES
Tell us whether the loop started after an update, a storm or an outage, whether the timing is regular, and how far boot gets. Those observations often halve the bench time your set needs.
MEASUREMENT
We monitor the supply rails through several boot cycles before naming a culprit. That discipline means the fixed price you approve targets the genuine fault, not the more convenient theory.
OUTCOME
Whichever side the fault fell on, the repair ends with extended soak testing through dozens of boot cycles and hours of running. Restart faults do not leave our bench on good behaviour alone.

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 photoThe timing strongly suggests software: an update that installed incompletely or corrupted the storage will crash the boot sequence repeatedly. We still verify the power rails first because coincidences happen, but most post-update loops are cured with a recovery flash of official firmware, which is quick, economical work once the set is on the bench.
Heat-dependence points towards the power side, typically capacitors or a regulator that behave until temperature degrades them, though a storage chip failing when warm can imitate it. This is exactly the ambiguity our scope measurements resolve. Mention the warm-up pattern when you book, because it tells us to run thermal testing from the start.
Both common cures are affordable relative to replacement. Firmware recovery is among the least expensive jobs we do, and power supply rebuilds involve standard components rather than scarce boards, keeping them to a small fraction of a new television's price. The fixed quote follows diagnosis, so the figure you approve reflects your actual fault.
The classic unplug-and-hold-power trick discharges the set and occasionally clears a one-off glitch, and it costs nothing to try once. A loop that survives that ritual has a real underlying fault which repeated unplugging will not heal and may be aggravating, particularly on the power side. At that point measurement by a technician is the economical next step.
Same-day collection is standard across our Gauteng coverage. Boot loop diagnosis is usually quick because the fault demonstrates itself continuously, unlike intermittent problems that hide. Many restarting sets are diagnosed on the day of collection and returned within a couple of days of quote approval, subject to parts for your model.
Not if the true cause was addressed, which our scope-first diagnosis and post-repair soak testing are designed to ensure. The workmanship carries our written guarantee, so a recurrence within the cover period returns to the bench at our expense. Power-side repairs also get our practical advice on surge protection, since Gauteng's grid caused many of them.
