AS15-F Gamma IC QFP-48 T-CON TV LCD LED – Negative Image Repair

Does your TV display a negative image, inverted colors, a whitish haze, or a solarized image while the sound remains intact? The gamma correction circuit on the T-CON board may be the cause. This datasheet is exclusively for the AS15-F.

Symptoms that may be associated with the gamma circuit

• Negative image or inverted colors
• Solarized or posterized image
• White haze or milky appearance
• Abnormal color cast

These symptoms may also be caused by another component on the T-CON board or the panel: replacing the circuit alone does not constitute a diagnosis.

Essential check before ordering

Read the marking engraved directly on the chip of your T-CON board. It must indicate exactly AS15-F. The references AS15-G, AS15-F, AS15-HG, and AS15-HF are not presented as interchangeable: order the suffix that is strictly identical to that of the original component.

Choose your quantity

• 1 piece — for a single repair
• 3 pieces — to have spares
• 5 pieces — workshop or repairer format
