WebApr 5, 2024 · A new inverter may be needed to power the LEDs, costing $7 to $75 before labor, or an average of $40. In some cases, a repair shop can convert a CCFL backlight to LED without installing a new inverter. Backlight failure in a TV may also be due to failure of the power inverter that supplies power to the backlight. WebJan 20, 2012 · The book’s Figure 32 shows the schematic diagram for a low-cost, variable-voltage PMT power supply based on a BXA-12579 inverter module that is originally designed as a power supply for cold-cathode fluorescent lamps. This under-$20 module produces 1,500VAC at around 30kHz from a 12VDC input. WebMost Cold Cathode Fluorescent Lamp (CCFL) circuits require an input supply of 5V to 30V and are optimized for bulb currents of 5mA or more. This precludes lower power operation from 2- or 3-cell batteries often used in palmtop computers and portable apparatus. A CCFL power supply that operates from 2V to 6V is detailed in Figure 35.9.
