Home/TV Repairs/TV Backlight Repair and LED Strip Replacement
TV Repairs
From a dark half of the screen to total blackness with working sound, backlight faults are the most common major repair on modern LED televisions, and they are firmly our home ground.
The details
Behind every LED television's picture sits an array of light strips, and behind most backlight complaints sits the same story: diodes run hot, age, and eventually one fails in a way that takes its whole strip, or the entire array, down with it. The symptoms range from a screen dimmer than it used to be, to one half noticeably darker than the other, to patchy clouds of shadow, to the classic fully black picture with sound still playing. All of them end up on our bench, and all of them have well-established cures.
Our process is deliberate and thorough. The set is opened on a padded bench, the panel and diffuser layers are lifted with proper care, and every strip is tested diode by diode rather than eyeballed. We fit complete matched strip sets instead of soldering in lone replacement LEDs, because mixed old and new diodes differ in brightness and the remaining old ones are already living on borrowed time. Before reassembly we measure the driver board's output current and correct it where the design runs strips harder than they should be run.
That last step matters more than most people realise. Overdriven backlights are the reason so many televisions fail young, and simply installing new strips into an aggressive driver invites a repeat performance. Falcon TV Repairs quotes the whole job at a fixed price upfront, completes most backlight work quickly, and stands behind it with a written guarantee.
What we cover
The specifics, in plain language.
SYMPTOMS
Sound with a black screen, one dim half, dark horizontal zones, visible bright spots where lenses have fallen, or brightness that drops suddenly during viewing. Each is a recognised stage of LED array failure.
TORCH TEST
Shine a phone torch at the dark screen while the set plays. If shadowy images appear under the beam, your panel is alive and the backlight is the fault, which is precisely the repair this page describes.
STRIPS
Strips age together, so when one diode fails its siblings are close behind. Fitting complete matched sets costs slightly more than a single strip but prevents the frustrating cycle of repeat failures every few months.
CURRENT
Many manufacturers run their LEDs near thermal limits for showroom brightness. We measure and, where appropriate, trim the drive current so the replacement strips live a far longer life than the originals managed.
QUALITY
We source strips matched to your panel's specification rather than the cheapest generic rolls, because lens geometry and diode binning affect picture uniformity. The difference shows in even lighting across the screen.
TURNAROUND
Same-day collection across Gauteng is standard, common strip sets are often on the shelf, and most backlight jobs move through the bench promptly. You get a firm return date with your fixed quote.

WhatsApp a photoThe torch test settles it in most cases. With the television on and playing, shine a bright light at the dark screen from a sharp angle. Faint moving pictures under the beam mean the panel is drawing images and only the lighting behind it has failed. No image under strong light suggests a different fault, which our diagnosis will identify instead.
Yes, a dim half or dark band means some strips have failed while others still light, and the fix is the same strip replacement described on this page. Do not wait too long though; the surviving strips are usually being driven harder to compensate, and full blackout tends to follow within weeks or months.
It is consistently one of the best-value major repairs in this trade, coming in at a small fraction of replacing the set. You are effectively renewing the component that wears fastest while keeping a panel, mainboard and power supply that still have years in them. The fixed quote we give before starting lets you judge the value directly.
For popular models whose strips we stock, the bench work is typically done within a day or two of collection. Less common sets wait on strip delivery, and we tell you honestly at quote stage rather than promising dates we cannot keep. Collection itself is same-day across our Gauteng service area in most cases.
In untrained hands, very; the panel is thin glass and the diffuser films scratch easily. This is exactly why backlight work belongs on a proper bench with padded supports and dust control, not on a lounge floor. Our accredited technicians do this daily, and our written workmanship guarantee covers the job, which tells you how confident we are in the process.
Yes, and uniformity is part of our final inspection. Because we fit matched strip sets with correct lens geometry and set the drive current properly, the restored picture is even across the screen and fully comparable to the set when new, sometimes with better longevity thanks to the current adjustment.
