Hv490fhb-n80 Datasheet -
The "N80" suffix usually designates the specific model revision or series. In the context of industrial displays, a 49-inch panel is a popular form factor for:
The datasheet emphasizes strict power sequencing:

While 4K input is not supported natively, the panel can display a downscaled 4K signal if the system's GPU or a dedicated scaler chip is used. The "N80" suffix usually designates the specific model
Do not exceed 50°C ambient without forced air cooling. The panel may experience image retention or permanent "mura" (uneven brightness) if overheated.
Because the HV490FHB-N80 is an open cell, it is often found in the repair market as a replacement part for popular TV brands like LG and Philips . Its 12V typical power supply and standard 51-pin LVDS interface make it highly compatible with various third-party T-CON boards and mainboards. It is designed to operate in temperatures ranging from , making it suitable for most indoor environments. HV490FHB-N80 - AG Displays The panel may experience image retention or permanent
| Symptom | Possible Cause | Datasheet Solution | |---------|----------------|---------------------| | No display, backlight on | No LVDS clock or incorrect polarity | Check LVDS differential pair termination (100Ω) | | Flickering image | PWM frequency too low or ground loop | Increase PWM to >240Hz; separate analog/digital grounds | | Vertical lines | Broken LVDS cable or loose connector | Replace cable; re-seat with locking mechanism | | Dim corners | LED strip aging | Replace backlight LEDs (requires cleanroom) | | Image retention | Excessive temperature or static image | Reduce brightness; implement screen saver |
