| I'm looking a Optiquest Q7 LCD monitor schematic. The numbers on the mainboard are: 790391200600, WB4BR, these are written on the component side.
The following numbers are on a bar code on the circuit side: 790391200601, Y706LAB6067H2. The problem is on the CCFL part of the board. I get NO backlighting. I suspect the OZ9910GN (Dual Forward PWM controller) or both of the AOP605 Complementary Enhancement Mode Field Effect Transistors. I need a schematic to confirm. Thanks for any help. |
