Haier L26B1120
This latest roadside find was totally dead. Haier is a Brandsmart brand. Its a 26 inch CCFL built in 2011. The fuses and caps all checked good but an FET was shorted. It was an AP4511GH which is a surface mount TO-220 style on the bottom side of the circuit board. That's an unusual FET in that its really 2 FETs in one package, an N-channel and a P-channel. It was unobtainable stateside but I found 2 for $5 out of China on Ebay. It was an easy repair if you're careful.

Sometimes a zener will go bad and take out mosfets it’s rare I feel that a mosfet would just short for no reason unless something else is going or maybe a defect.

With any luck, all it will need is the mosfet, but sometimes you lose the gate driver as well. John |
