Re: Buying transistor advice Dell E173FPc - 2 Seconds to Black
I finally got onto a DMM, the capacitor is giving 0.018 microfarads. I'll try to find a stats sheet. Wait, I think somebody else talked about this in this string....

I didn't really want 30 of these inverter/ transformers, but the parts which they used to make this old monitor are hard to find and you almost have to go with whatever you can find. If I do end up using this part, I think it is good judgement to replace both of them so they will match.Leave a comment:

Just got back from holiday leave and finally received 30 of these, the old one is: an 80LL15T-7-YS G 0523, and all 30 of these are:
80LL15T-7-YS G 0716.
Though if that was simply a bad connection as you said then the old one is possibly still good.
I am working to line up a DMM (to check capacitance), frequency generator and oscope (the university labs are closed currently) to work through those service guides you graciously forwarded. Though, I noticed that the service guides...Leave a comment:

I'll look more closely at the other posts.
Edit: I see the image is not uploading. I'll try to figure that one out.Last edited by 3Focus1; 12-13-2016, 09:01 AM.Leave a comment:

I am new at this. I am a second year EE student at LeTourneau University and don't know the best places to look for parts.
I have a monitor, Dell E173fpc which won't stay on, it sort of fades out. No blinking of the power light. I could just buy a used monitor for 20-30$, but I'd like to troubleshoot this one for practice. The power supply board 715L1283-4. Regular capacitors seem fine. No bulging etc. However,
