Help on part

Hey Team,
Hope all are doing well, new at this and not sure what this part is. Transistor? have tried to reserach the numbers with not luck. Its on the driver board of a 52 LCD tv.

Thanks

A "D" is a diode. See

Typing in "kjh diode" in your favourite search engine leads to

Re: Help on part

It can be Dual Diode with either common Cathode or Common Anode at the middle pin or single Diode. Just test the other one by putting the meter in Diode mode, black lead to the middle pin then use the red lead to probe the outer legs, if it is common Cathode, the meter should show 0.5~0.6V between the middle pin and each outer pin. If it show OL, or 1 the reverse the leads, if it now show 0.5~0.6, then it is common Anode.
Other circuits may be shorted that is why it tool out the device.

I also got a BAV70 from google search.

Hey thanks, you guys are the best!!! I need to find some more time to learn what all the circuit board numbers/letters represent, that would help me a lot. Again Thanks

Re: Help on part

Just use two 1n4148 from Radio Shack for testing. But I think there are larger problem that cause the Diode to burn up like that.

It was my fault, 3 pins on the Flat cable wire from this board to TCON were peeled up when I put it back together. turned on and poof.
