MJD44H11 has significant lower gain and transition frequency, better get the genuine part. Regards, Dieter

My LCD monitor died. (Continuously attempts to power up, fails, and restarts the power up attempt.) Naturally I have no schematic for it. That said, I found a shorted SCR (overvoltage circuit is my assumption) and a shorted



2SC5707 Sanyo NPN. Any idea of what to substitute for the
2SC5707? I'm clueless as to what it does in the monitor without a schematic.

If it matters, the best I can come up with on paper by searching through Mouser, Digikey, Onsemi, Fairchild is a D44H11.



Thanks, Ed


Why not get the correct part?

Hi ! Ed,

We do have stock of the 2SC5707 from warehouse. For this repair job, I cannot sure, if you replace the 2SC5707 is OK or not.

We cannot sure your idea price for this component. But our shipping cost may be around US$25.00

Thanks !

Thanks to those who replied. I'll use one of the links posted to buy a 2SC5707 - or scrounge one from a defective LCD monitor. Turns out we have "recycling day" scheduled for Nov. 4 and I may be able to get a broken monitor there.

Hi ! Ed,

Can you tell us which package you request ?

As there is several package of the 2SC5707, we cannot sure our warehouse's package is right package.

Waiting for your idea !

Thanks !

Hi Patrick,

I do not know if 2SC5707-TL-E is the same. If you can send me a sample, I can tell. But then I won't need to buy one.

Your call.

Thanks, Ed

Nope. Couldn't get a monitor, so I'll order the part.

Ed

The parts *finally* arrived this afternoon. The package was marked "returned for postage" so that explains the delay. I may get a chance to install the transistor & scr this weekend.

Ed

Finally got the 2SC5707 and installed it. Monitor works fine now. Thanks to all who replied! :-)
