3. **Accessibility** These boards are relatively easy to find on eBay, AliExpress, or specialized TV repair marketplaces, with prices typically ranging between $100 $200 depending on condition and seller.
4. **Potential Longevity** If the TV s display and backlight are functional, a new board can extend its usable life for several more years.
