Hello all,
I have limited understanding of this kind of stuff, so please bear with me.
I have an issue with a back light on an LCD monitor out of a car. I believe I've found the cause of the problem, a burnt diode and a burnt transistor (I think that's what they are anyway). Here is a photo of the suspect parts .
I've found someone that can de-solder the old bits and solder the new bits for me, but he was unable to find the replacement parts! I think I found the correct transistor here, not sure if the 2S prefix makes it different, or the fact that on the bottom right of the part my one has "23" and the one pictured has "67" (what does this actually represent? Revision number?). Would that transistor work as a replacement?
But I and a few other places have had no luck finding a replacement for the diode, J4S 23. The guy I spoke to who will be doing the soldering for me said that it wasn't an issue, and that he can find a similar diode that "should work". I'm a bit hesitant to just go by something that "should work".
I found another thread here that has been the most helpful of all. From what I can gather when putting the site through a translator, this guy describes the same symptoms as my problem, he has the same two burnt parts, and he himself replaced them which fixed his problem. But he too had trouble finding J4S 23 (again, what does the 23 represent?), but in the end he said he used F2J4S, which I am having trouble finding.
Basically, what is a suitable replacement for that diode, and will the transistor I mentioned above be suitable? I am assuming that you guys will see this information and be able to give me an answer with ease, but if my assumption is incorrect and leg work is required, could somebody guide me in to the right direction so that I can find the suitable replacement?
Thank you.
