Description

HV430FHB-F90 DCBHM-B268B_14 TCON Board

The part numbers you provided correspond to a Timing Control (T-Con) board specifically designed for a 43-inch BOE Full HD (FHD) LED/LCD TV panel.

• HV430FHB-F90: This is the model number of the 43-inch, 1920×1080 resolution (FHD) open-cell LCD display panel manufactured by BOE. It operates at a 60Hz refresh rate and uses ADS (IPS-like) technology.
• DCBHM-B268B_14: This is the specific manufacturing part number or PCB identifier printed on the T-Con board that interfaces with that exact BOE panel.

• Interface: Usually utilizes dual 68-pin Flexible Flat Cables (FFC) or mini-LVDS interface to transmit video data directly into the panel’s source scaler boards.
• Input Voltage: Operates on a typical 12.0V rail from the TV main motherboard.

• No Display / Black Screen: The TV turns on, and the backlight glows, but no image or menu shows up. This often points to a blown T-Con fuse or a failed power management IC (PMIC) on the T-Con board.
• Double Image or Horizontal Flickering: A common issue with this BOE panel layout. It can sometimes be bypassed by skilled technicians using a “CKV line cutting” method on the side COF (Chip-on-Film) or using jumpers, though replacing the T-Con is often the first non-invasive step. 
• Vertical Lines: Frequently caused by loose FFC ribbon cables. Try cleaning the ribbon cable gold pins with an eraser and reseating them securely into the DCBHM-B268B_14 board sockets.
