It doesn't really matter 75012523 comes as a set. You can get refirbished ones also. I had one I tried to component level trouble shoot it after and couldn't figure out what was actually bad.

Thank you for the clarification of the part numbers. But I guess what i am really trying to ask is how do I test each of the boards individually to see which one is actually bad, or is it just a given that they both need replacing? Is there some point on the boards that I can meter to determine which is the actual bad one?

If I wanted to badger you ask vtech what happens. There are two panels Toshiba used so two different inverter sets. Try researching Toshiba's part numbers 75012523 BOARD, INVERTER BLP0021 FOR LCD AX080E002B Or 75012526 BOARD, INVERTER BLP0022 FOR LCD AX080A030B. Both are less than $100 plus a $40 core charge. There's places selling just the master or slave for around $189 but the same price for both. If you see 75012523-S or 75012523-M they are selling you just one. So 75012523 is the master slave and 75012526 is the single inverter.

Yes, your first reply was a useless flip response. You berated me for having not read a post which I obviously did, since I referenced specific advice from that thread. I originally posted the question here, but since there had been no activity on this particular thread for some days, I decided it would be better to post it as a new topic. I apologize if that was inappropriate. Now that I am following the correct protocol, are you going to continue to badger me, or will you just allow another person to assist me with my question? Thank you.

Usless flip responce? I guess if you post the same question in more than one place you'll get a faster answer. That's why we delete multiple posts.

So I have the correct voltages coming from my power supply board. I have the dark picture that I can still see if I shine a bright light. I have no buzzing at all. From what I read above, that tells me that I have a bad inverter board. How do I find out which board I need to replace, master or slave? Who currently has these boards in stock? Thanks.

Above post was mine. I registered here because this site seems to be very useful. I have a lot of learning and catching up to do and have been getting more and more electronic junk in my side room to repair. I need to educate at least as fast as it piles up, lol. So how bout them there 32AV500U with the awesome designed dual invertered backlights.
