I have this TV with sound and no picture. I tried the flash light trick I could see shadow like figures. Can anyone help fix this?

You probably need an inverter....

Do you hear a sizzling/buzzing sound? if so that probably is the inverter...on my unit is was the slave inverter. No sound ...it still can be the inverter.

At this point you need to take the back off the set and see if it has one or 2 inverters. This model had 2 backlight designs. Early sets made(before April or May 2008) have 2 inverters. either way take the back off and look for one or 2 inverter boards.

If it only has one inverter replace it..if dual inverters and the buzz comes from the right side of the set (the side with the external AV input) that is the slave inverter.

I replaced both inverters on my set even though it just needed the slave inverter.

I have some parts for these sets including 2 tested and working hiu-813-m MASTER inverter boards. $60ea+shipping

What if you are having this exact same issue with a 32AV500U but neither inverter is making any sound at all, no buzzing, no nothing? I have no clue which one is bad and have inspect both visually. Obviously you can't tell squat by looking at them. I put the television back together for now until I can find more information on how to test these. These pieces of crap almost aren't worth replacing with the same parts from the same failed engineers. I told the owner of this set (my wifes aunt) that I would throw it away and buy a better set before I would invest more than $100 in this thing on the same failed parts that will probably blow again in a month or a year, but she insists on having it fixed.

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.

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.

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.
