Gamma voltage fault.
Some repairers use the HV320WXC-200 schematic to create a “universal TCON” by bypassing the built-in TCON and using an external controller board. The schematic reveals: hv320wxc-200 schematic diagram
With the shift to 4K panels and integrated TCON (i-TCON where the main SoC drives the panel directly), the standalone schematic for legacy panels like the is becoming a collector’s item. However, because millions of 32-inch HD TVs remain in use, this knowledge will remain relevant for at least another decade. Gamma voltage fault
Always compare the ICs on your board to the schematic. If the main TCON IC matches (e.g., or CM2801A ), then 80% of the schematic applies. However, because millions of 32-inch HD TVs remain
You will not find a publicly released, factory-original schematic for the LCD panel itself. However, for troubleshooting and repair, you do not need one. Focus on:
If you cannot find the schematic, you can reference known donor boards that are compatible. These boards follow the same schematic as the HV320WXC-200.
