$5,000.00 TV in 2015. Not going to trash it just yet. Power Board can be had for $64.95. I'd rather waste that much money troubleshooting than give up.

Re: Samsung UN78JU7500FXZA 8 blinking light code
So, are all the odd numbers on top and even numbers on the bottom?Leave a comment:

Re: Samsung UN78JU7500FXZA 8 blinking light code
Have watched the video several times. Video shows connector with just 1 row of wires on the connector with relative ease of knowing which Pin is Pin #1. Connector on my Samsung has 2 rows of wires. I don't know how to determine which row begins with Pin #1. If the numbers 21/22 at the bottom left of the picture are telling me that pins 21 and 22 are on the left hand side of the picture, is the top wire 21 and the bottom wire 22? Or, vice-versa?...Leave a comment:

In trying to get readings from my Klein meter, I've been having trouble getting valid readings by inserting my "red" lead into the connector as shown in several different videos.
I have unplugged the connector (shown in the picture) from the Main Board - the board that has the RCA, HDMI, etc. connections. The other end remains connected to the Power Board; so, I'm assuming that voltage readings are still valid. In this manner I'm able to touch my "red" lead to each of the silver squares as pointed to in...Leave a comment:

Re: Samsung UN78JU7500FXZA 8 blinking light code
Let me refer to post #26 first.
Problem 1) Not sure if it's my particular Samsung model or not, but I do not see a backlight anywhere on the back of the TV. Have looked at other videos and most show an orange? light that gets referred to; however, I see no such light on this back panel.
Problem 2) In reference to the legend I posted showing voltage settings for CNM803, it looks as though ANY voltage reading I receive on my tester should be 13v. I see no other voltage readings on the legend. Is this correct?Leave a comment:

Re: Samsung UN78JU7500FXZA 8 blinking light code
This should be it.
Am I still following your instructions from a previous post, i.e., test before plugging in the power; then, test after plugging in the power?...Leave a comment:

Re: Samsung UN78JU7500FXZA 8 blinking light code
This legend is for CM803 - correct?
I'll still be following your instructions in one of your initial posts? That is, test before plugging in power; then, test again after plugging in power?...Leave a comment:

This is CNL802B - located just under CNL802A. Again, legend is there but not what I'd expect to see for voltage readings....Leave a comment:

This is CNM803 - at top left of Power Board just under CN9003.
I see no legend of any kind associated with it....Leave a comment:

I don't want to make any mistakes here, either. I'm going to send better pics of these connectors.
This is CN9003 - at top left of Power Board. I seen no voltages in the legend associated with it.

Last picture of main motherboard is getting uploaded now.
I've watched the videos attached to your post relative to testing. I have no problems determining different boards on a computer; but, I'm a novice when it comes to the boards shown in these pictures.
Can you highlight one of these pictures so I'll know what to test?...Leave a comment:

Am uploading an overall view of the back of the TV. Also, individual pics of the different boards.
TO nomoresonys: I've spent the last several hours using the "standard" reset processes, i.e., all the ones that I could find on GOOGLE.

Samsung UN78JU7500FXZA 8 blinking light code
For the first time in 4 years I unplugged my Samsung TV last evening to plug in a ROKU.
TV is wall mounted. To clean up some loose hanging cables, I slid my TV about 8 inches to the left of its original position in order to give me a bit more space. My wall mount allows for this.
I unplugged the TV from the wall outlet before doing this. I mounted my Dish TV box to the wall, my Samsung "oneconnect" to the wall, and used some plastic wire ties to bundle up my loose cables. Everything was plugged back in as before to the "oneconnect", Dish TV box, etc.
