Hello, I am not try to give you guys A hard time.
I am troubleshooting A INSIGNIA NS-29D310NA15, One board TV (PCB: TP.MS3393.PB703), under $100 TV, I ordered the PCB at US $34.42.
Yes, I can change the PCB and fix this TV in 5 mins, but I want to fix the original problem otherwise Im gonna learn nothing.
Question : HY9 is a Zener for ? voltage
I use Haier 32" service manual fix this INSIGNIA 29" TV. From pic2, my guess is (HY9) a sot-23 9v Zener!
PS: I can use poormans LED tester to test another good parts (zener).............
