Toshiba REGZA 4K UHD & QLED TV Repair in Ghaziabad
Searching for Toshiba REGZA 4K TV repair in Ghaziabad? Toshiba REGZA 4K models (C350, M550 series, 43" to 65") feature the REGZA Engine 4K and Quantum Dot color technology. A frequent fault reported in Indirapuram and Vaishali is that the TV powers on with audio playing clearly from set-top boxes, but the picture stays pitch dark. This occurs when an LED burns out on the backlight array, opening the power loop. Our technician measures backlight voltages, fits brand-new aluminum-backed LED strips, and calibrates driver current. Repairs typically range from ₹1,550 to ₹2,950.
