Haven't had a chance to tear it apart yet, last minute work trip. Hope to start this weekend.

Re: Samsung UN50EH5300FXZA, black screen
Perfect, thanks!
I don't recall what the back-light level was set to, but I imagine it was pretty low. I don't think I used my Avia setup DVD on this TV (I probably grabbed settings off of a forum) but I usually like a dimmer setup. It was probably the sheer number of hours it was on. This was the main TV for the wife and kids, and I would guess it was on for an average of 18 hours a day.Leave a comment:

Thanks for the video link, very helpful!
So, if I decide to do the stacking method, can someone recommend the best LED strip to buy for this?
Thanks.Leave a comment:

Thanks, I'll try to start the disassembly this weekend, and I'll look for Reece's videos.

Re: Samsung UN50EH5300FXZA, black screen
Do I replace them all, or do I need to test for the bad one?
These are out of stock at the link you provided; any other ideas as to where to get them? My searching proved futile.
Thanks again for your help! I would've just ordered a main board and been out $60.

Re: Samsung UN50EH5300FXZA, black screen
With the power board plugged into AC, I get 331v regardless if that connector (CNL802) is plugged in or not. If I plug in the cable to the main board (CNM803) and hit the power button on the remote (going from standby to on) the voltage drops to about 233v (slowly I might add, it took 10 to 15 seconds to fall from around 260v).
Thank you!

Re: Samsung UN50EH5300FXZA, black screen
Here are the voltages you asked for:
Pin 1 (B13V) = 12.5
Pin 13 (B5V) = 5.35
Pin 6 (BLU-ON) = 3
Pin 12 (A5V) = 5.35
Pin 14 (PS-ON) = 3.35
CNL802:
Pin 1 (D+) = 331.4
These were measured from the original board, not the replacement that I purchased.
Thanks again!

Sorry, missed your question about the glowing lights. No, no light at all.

Re: Samsung UN50EH5300FXZA, black screen
Thanks for reply! I tried unplugging the cable between the power and main board, but no luck. Still have a black screen. What's next the next thing to check?
Thanks again!

Samsung UN50EH5300FXZA, black screen
According to the people present at the time, it just turned off. So I assumed the power supply was bad. I ordered one off of eBay (supposedly out of a new TV with a cracked screen), but it didn't fix the problem. The standby light is on, and when I press the power button on the remote, the standby light blinks 4 or 5 times.
I've looked for a datasheet for both the TV model number and for the main board model number (BN94-06882C) but neither are listed. I hate to keep playing "SwapTronics" and just buy a new main board without knowing if there's a way to test it. I have... -
Re: New Members - please post your introductions here
Greetings! Tired of throwing money at my TV playing "SwapTronics", so I thought I'd try to learn how to diagnose this thing a little further.
I'm a robotic assembly tech and scared of anything over 24 volts.....
Thanks!Leave a comment:
