I have.a Samsung UN60EH6000FXZA. Occasionally, when i turn tje tv on the screen is black. After abiut 30 seconds i jear the sound fro. The channel i have on. Usually if i power it on and turn it back on again the picture comes up. Sometimes i have to manually turn it off then back on to get the picture to come up. I'm assuming this is a t-con board issue. Am I correct? Thanks

SOURCE: no picture just comes sound

sounds like the Backlight has failed, if you look closely at the screen you should be able to see the image changing, but as there is no back light there is no luminescense so it will appear black or grey, It is probably the backlight inverter or element that has failed, if this is within warrany organise with them to fix it for free,

I fixed it. Went back in after a twenty min. break, figured if it's broke I can't break it again, might as well try to fix it(out of warranty, so much time on 1st. bulb, after fixing I found out had 8463 hrs. on 1st. lamp! WOWW most i've seen on any strings out there,and I'm really cheap and inquisitive) But this is how I did it. pulled off covers. looked around pulled light box out checked connectors and resistors visually for burns, none found, then I see a clear plastic sleeve covered group of wires it was plugged up at the ballast where i was working earlier but not the other end, so i looked around for the plug to insert it, couldn't see any where. I felt on top of a silver polished panel w/holes allover, there on top, at the right side of the silver panel was a plug for it. I plugged it in by removing fan and cooling fin assembly, for room to work(and good chance to clean dust from the fins and fans. I tilted silver panel down to see the top, after some removing spring loaded screws holding cooling fins, (the screws ave very light spring tension and won't pop out, I swear, keep track of springs for reassembly later) plugged it in(only goes one way, don't force it, flip over if it doesn't fit nicely) replace all removed parts in reverse order and reinstall covers, plug up, and mine powered on almost instantly. After that and spending 2 hrs. online trying to go through all the strings everywhere about these problems. It came down to trial by fire. I hope this helps, reply if it doesn't.

SOURCE: sound no picture, which component is tcon board? where all audio/video/cable/hdmi plug in to?

for bn94-00963b go and change your backlight inverter

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.
