Re: Problem with Samsung UN55ES6150F - Wont power up, 10 standby blinks
It was the power supply. Used piece from shopjimmy fixed her right up. Should have gone with my gut and replaced it first; the fact the backlights didn't come on with the mainboard disconnected should have been the proper tell, but I was flustered and the standby light WAS blinking (had [i]some[/i] power, anyway), in my logic's defense.
I think I'll rebuild my bad PSU and keep it around as a spare.Re: Problem with Samsung UN55ES6150F - Wont power up, 10 standby blinks

Re: Problem with Samsung UN55ES6150F - Wont power up, 10 standby blinks
This has been interesting, but I think I've reached the point where I should just wait and see if the replacement main board fixes everything. You've been very helpful and I'm 95% sure I've followed your instructions correctly but I'm afraid I'm going to accidentally electrocute myself on the power supply. Also I haven't got any resistors to perform the next step with anyway.Leave a comment:

Pulled the Pin6 wire from the connector. Standby light still blinks as before / tv behavior is unchanged. Also tested voltage again at the Pin6 wire and again read zero volts. Tested continuity to ground and there is a circuit, just no voltage.
I really appreciate your help, by the way.Last edited by ralphlamao; 03-15-2015, 08:08 PM.Leave a comment:

Re: Problem with Samsung UN55ES6150F - Wont power up, 10 standby blinks
Unfortunately there is no "on" anymore. As soon as power is applied (with the main board plugged in) the standby LED blinks an error code (5 groups of 2 blinks) and the set does not respond to commands either by remote or the power button. I tested Pin6 twice, the second time to make sure nothing happened when I pressed the power button. Same result both times.
What will pulling the Pin6 wire accomplish? I should be able to easily de-pin that wire from the connector.Leave a comment:

With the main board harness plugged in and getting a reading off of a needle jammed in the back side of harness @ Pin 6 I read 0.0v to any connector ground or chassis ground.Leave a comment:

Re: Problem with Samsung UN55ES6150F - Wont power up, 10 standby blinks
I get which row is odd and even, I just need to know which two pins to short to turn on the rest of them as per the video link I posted. Granted, I don't even know that my Samsung is supposed to work the same way.
Anyway when testing each pin to chassis ground the only one that registers is Pin 12: A5V, and I get ~5.2v.
By the way I went ahead and ordered a new input/logic board. Kind of a shot in the dark. I also asked ShopJimmy.com for help but in spite of their claims of excellent...Last edited by ralphlamao; 03-14-2015, 07:45 PM.Leave a comment:

Re: Problem with Samsung UN55ES6150F - Wont power up, 10 standby blinks
Bump - please, help, it's day 3 and I was totally unprepared for the descent into madness I'm experiencing without my TV.
This picture is of the connector on the power supply for the harness between the power supply and main board. The pinout diagram is to the right. The youtube link I posted above mentions shorting out a couple pins in order to turn on the rest of them so that I may test voltages but because of the differences between the COBY in the video and my Samsung I'm unable to tell which...Leave a comment:

Re: Problem with Samsung UN55ES6150F - Wont power up, 10 standby blinks
Any suggestions for testing whether or not the power supply/LED driver board is getting the correct command signal from the main?
edit: Found this link, and although it's a different manufacturer and board layout I feel I can probably use it to test my power supply: [url]https://www.youtube.com/watch?v=mUvclBfaMXg[/url]Re: Problem with Samsung UN55ES6150F...is getting theLast edited by ralphlamao; 03-14-2015, 08:22 AM.Leave a comment:

Re: Problem with Samsung UN55ES6150F - Wont power up, 10 standby blinks
Main filter VDC is steady at 390v with the main board disconnected. Also tested what I assume is the LED Backlight harness which showed .8v on the two "R+" leads when grounded to the chassis, but saw no voltage between R+ and R-, nor between L+ and L-, or L+ and chassis ground.
What else should I test?Last edited by ralphlamao; 03-13-2015, 07:17 PM.Leave a comment:

Re: Problem with Samsung UN55ES6150F - Wont power up, 10 standby blinks
Wow, thanks much for the quick reply, I'll borrow my dad's meter and check what you recommended.
As for history I'm the original owner. We did have two power outages today, so some surges may have accompanied them but that was almost 7 hours prior to the time of failure. Always been plugged into a Belkin surge protector, for whatever that's worth.Last edited by ralphlamao; 03-12-2015, 10:27 PM.Leave a comment:

Re: Problem with Samsung UN55ES6150F - Wont power up, 10 standby blinks
Hello,
Sorry about reviving an old thread and all that but it's the only half-useful thing that's come up in my searches.
I've got this same TV and my power light blinks 10 times (5 groups of 2) as mentioned by the OP. If I follow the above troubleshooting step (disconnect cable between power and main boards) my back light does Not illuminate. Would this indicate the power supply is the culprit? I haven't got a multimeter but a visual inspection revealed no swollen / bad looking...Leave a comment:
