Smart TV Repair Services (LED, LCD, OLED, QLED)
SR Technologies is a leading provider of out-of-warranty TV repairs in Kolkata and Howrah. We specialize in fixing modern display display systems and display boards. Instead of spending high amounts replacing complete screens, our engineers troubleshoot down to the component level.
TAB / COF Screen Panel Bonding Machine
High-precision bonding resolves horizontal/vertical line issues without screen replacement.
LED/LCD Panel Bonding
Vertical lines, horizontal bars, or half-screen blackouts? We use advanced COF/TAB bonding machines to precisely repair line connections on the glass substrate without screen replacements.
Backlight Failure Repair
Sound working but display stays completely dark? This is usually a backlight LED strip failure. Our technicians carry diagnostic gear and replace damaged LED arrays on-site.
Motherboard & Power Board Fix
TV not turning on at all, or red standby light blinking? We repair shorted transistors, capacitors, and memory ICs on the power boards and main boards.
Smart TV OS & HDMI issues
Faulty HDMI ports, WiFi connectivity issues, or OS boot loops? We repair inputs, re-solder board connections, and flash firmwares to get smart features working.
