That wasn't meant to be condescending but was meant to get your information in a more concise manner. And you said yourself you *think* they regulate voltage.
But whatever, best of luck to ya.

yes I saw one at sj, said 20 bucks, theyr sold out, I bet when they get another in stock it won't be 20, I notice that a lot on the parts selling sites, the ones that are sold out have low prices next to them, but the similar ones in stock are about 4 or 5 times higher, I'm thinking its some kind of strategy they use to get you to come back to their site.

rf is the tuner where the coax goes on to. Analog produced snow and that is what I thought you meant. Anyway... your pics show some weird combo of snow and it looks like the OSD is trying to display something, but it can't. If you have a oscilloscope, you could check all these little caps for DC ripple. Little ripple who cares, but big ripple creates a problem. If that doesn't yield nothing I would point at that big main chip first or a different IC between it and the LVDS output. But just changing IC's isn't efficient, if you haven't got clean power coming from the SMD caps. Didn't I see a new board for $20 at SJ?

not sure what samsung should display, but not being able to see menu is surely a sign of malfunction, might have to buy a mainboard, tv is 9 years old, thats why I hesitate to buy one.Last edited by nomoresonys; 02-08-2015, 09:10 AM.

snow is usually the rf input.

thanks CapLeaker, when I click source the snow changes a little, it makes me think it's responding to the remote, but the snow is so dense, can't make out any image that might be there.

You had posted the SJ pic already before on the beginning, so you did not forget. Hi! I'd say follow the video input traces. Usually they go to a main chip. I would think that it generates the OSD display, before it goes out to the LVDS.
Since the TV shows static, can you still change the input, to HDMI or something?

[QUOTE=mmartell;528630]Search "how to test a voltage regulator" and post the info back as per instructions. Assuming of course these are voltage regulators you are talking about. Your coming off as CONDESCENDING, if you think you need to be rude to help, then go be rude to someone else, I don't need it.

the ics I'm looking at are ic101, ic102, ic1702, and 7 or 8 more on the bottom. http://www.shopjimmy.com/samsung-bn9...main-board.htm

not sure CapLeaker, no background on it, the menu may be there, the snow changes slightly when I toggle thru source, but the snow is too dense to make out anything, so I can't tell if theres a menu.

So you are getting a input signal, but no menu or any OSD? Is it a lightning strike special?
