The is a 49-inch a-Si TFT-LCD display panel manufactured by BOE Technology Group Co., Ltd.
: 1920 x 1080 (FHD) with a 16:9 aspect ratio. Active Area : 1073.78(H) x 604(V) mm.
The panel also boasts a contrast ratio of 1400:1. While modern high-end consumer TVs boast "dynamic" contrast ratios in the millions, a native contrast ratio of 1400:1 is excellent for commercial IPS panels, providing deep blacks and clear text legibility.
First, I should try to find the datasheet online. Let me do a quick search for "hv490fhb-n80 datasheet". Hmm, the results aren't showing up. Maybe the part doesn't exist under that exact naming, or it's a non-standard part. Perhaps it's a typo or a custom part. Alternatively, maybe it's from a less-known manufacturer or a newer component not widely indexed.
| Original Component | Replacement Action (using HV490FHB-N80) | | :--- | :--- | | | Used for repair of Skyworth 49E3500 (requires mainboard conversion). | | HV490FHB-N8A / N8D | Direct replacement potential, but pinouts and board firmware must be checked. |
Possible components: High-voltage MOSFET, IGBT, thyristor, or diode. Let's consider a high-voltage diode. If it's a diode, maybe a Zener or a high-voltage rectifier. For example, the 1N5346 is a Zener diode, but that doesn't match.
