Frequently Asked Questions
Q: What TV screen sizes is the CA-266S LED backlight driver board compatible with?
A: The CA-266S universal LED backlight constant current board is designed to work with LED TV and monitor panels ranging from 32 inches up to 65 inches. Its wide adjustable output range (80–480 mA, 18–88 V) makes it suitable for a broad variety of LED strip configurations found across this size range.
Q: What is the input voltage requirement for the CA-266S backlight board?
A: The board accepts an input voltage of 10–28 V DC, making it compatible with most standard LED TV power supply boards. The output voltage range is 18–88 V DC, which covers the forward voltage requirements of the majority of LED backlight strips found in 32–65 inch panels.
Q: Is this board suitable for a DIY TV repair at home?
A: Yes — the CA-266S is packaged in a standard DIP form factor, which simplifies installation and soldering for those with basic electronics repair experience. However, working with television internals involves high voltages. Always ensure the TV is fully unplugged and discharged before opening the cabinet, and consult a qualified technician if you are unsure.
Q: Does this board work as a direct replacement for branded OEM backlight inverter boards?
A: The CA-266S is a universal constant current driver board, meaning it is designed to function as a compatible replacement across many LED TV brands and models rather than being model-specific. Always verify that your panel's LED strip voltage and current requirements fall within the board's specification range before installation.
