Re: Samsung UN65HU7250 T-CON voltages?

Ok, one more question before I do that, when the tv is on, should there be power at the coils? I dont get anything on any of them.

Re: Samsung UN65HU7250 T-CON voltages?

I am not sure how to test to see if the panel is correctly power supplied, I thought that is what I was doing in the video? Also, I am not sure what the voltages should be on the test points. Videos of other tcon boards have more than 1 volt on those test points, mine has about a half of a volt. I'm confused.

Re: Samsung UN65HU7250 T-CON voltages?

Ok voltage is same plugged into the panel or not.

Re: Samsung UN65HU7250 T-CON voltages?

Ha, nvmd I will try to test voltages with it half unplugged.

Re: Samsung UN65HU7250 T-CON voltages?

Well, I have done the disconnecting the board on half of it trick, but I havent been able to get any picture on either side. Not real sure what TP voltage means, thanks

Re: Samsung UN65HU7250 T-CON voltages?

Thanks for that, I learned a lot from it. I still have no idea what the voltages on a good t-con board would be, that manual didnt give them to me. I am pretty convinced that I just got a bad board from ebay.

Hello all, I have a 65" Samsung that has backlights and sound, but no picture. I recently purchased a used t-con board off ebay, and it didnt help. I have over 12 volts on both fuses on the tcon board, and the old board didnt have much of anything on the test points going to the panel. New board has a couple of the panel side points with 3 volts, but almost all the rest have less than half a volt.
From what research Ive done I think its supposed to have more than that? Could it be something from the main board thats not getting through?
I took a video of the tests, thanks...

Hello from Pennsylvania! My name is Steve, and have been tinkering with TVs as of late. I don't think I've had to actually buy one for quite a while, thanks to this forum.
