Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.

Sorry to hear you’re having trouble.

Can you see the menu screens at all?
If you hold a flashlight to the screen, are you able to make out any images that way?

Let me try
I cannot see the menu screen, but can see images with the flashlight

Hi Nathan, can you please let me know if you are getting these updates, my phone number is ***** and you have my e-mail address...I did not get any answers from you.
Expert:  Nathan replied 11 months ago.

My apologies for missing you earlier. Yes your messages came through, but the multiple replies can get delayed through the queue so I'm just now seeing them.

I've sent you an optional call offer, or we can continue here if you prefer.

Expert:  Nathan replied 11 months ago.

I'll plan to continue here, you can accept the call if you wish.

The most likely failure point here is the power supply/led driver board, though in rare cases the actual led lights can fail, you'd always replace the board first, which you can get here:

Note that there are a few versions of this, so double check your existing board number for an exact match before ordering.

Best regards,

Hi Nathan,Thank you for your answer, I ordered a power supply board. I should receive it soon. I would like to wait until I have installed it before giving you the rating so I can provide proper feedback. Hope it’s all good.Thank you very muchDan
Expert:  Nathan replied 11 months ago.

Yes that would be just fine, let me know how the power board works out and if that by chance doesn't help we can discuss further options for you.

Hi Nathan, I finally got the board. The package says "The latest software is not installed on this board. Make sure you download the latest TV software from SAMSUNG.COM....". Turns out, Samsung will not give you the software or download procedure. They say I must go to a Authorized service center. So, thinking this was just the latest software anyway, I installed the board. Now the TV does not do anything, it will not turn on or respond in anyway. I re-installed the old board and the TV is still completely dead. Any ideas as to what is going on here?
Expert:  Nathan replied 10 months ago.

It sounds like you may have a loose/missing connector inside. Put the old board back, power on if possible to test, then replace the new board and if it comes on you can try to manually install the latest software off the samsung site here: under the downloads tab

No luck, same results (P.S - I will be absent until Aug 22 - on vacation :-) )
Thanks Nathan
