At Tricity LED TV Repair, we specialize in advanced screen bypass and COF bonding machine work for LED and Smart TVs that have display issues at the panel level. These are highly technical repairs that most local shops cannot perform, but we are fully equipped with industrial-grade panel bonding machines, making us one of the most trusted repair labs in Chandigarh, Mohali, and Panchkula.
If your TV display shows vertical lines, half screen, dead rows/columns, or is completely white or black, the problem often lies in the COF strip (Chip on Film) or panel gate driver IC. That’s where our bonding machine and screen bypass expertise come in.
💡 What is Screen Bypass?
Screen bypass refers to a process where we reroute or deactivate a damaged part of the display circuit – usually due to a faulty gate line, shorted IC, or dead section on the panel – to restore partial or full screen functionality. It’s commonly used when panel replacement is too costly or unavailable.
While it doesn’t always restore the original quality 100%, screen bypass is a practical, budget-friendly option to keep your TV running, especially if the defect is isolated.
🔧 What is Bonding Machine Work?
Modern LED TV panels use COF (Chip on Film) technology – a set of delicate ribbons that carry signals from the T-CON board to the screen. When these connections are damaged (often from heat, pressure, or aging), you’ll see screen distortion, dead lines, or flickering.
Our bonding machine setup includes:
✅ Professional COF bonding machine
✅ Preheating & cooling temperature control
✅ Precision alignment fixtures
✅ High-quality COF strip inventory
We can rebond original COF ICs or replace them with new ones, depending on the damage, giving your screen a second life without needing a full panel replacement.
