Samsung PN60E6000GF 60" Smart TV turns off, red flashing power light

[kyij]

I recently got this TV used but failed soon after I got it. It will stay on for a little bit (a few seconds to a few minutes) and shut off. The power light does 2 short flashes, for 5 cycles and then one pause and repeats.

I have repaired a couple of TV's before, and didn't think it would be too bad to diagnose. No caps were obviously blown so I got a capacitor tester and only found one of the them to be 10% off. Replaced it today and still the same issue.

I tried looking up the manual but that didn't give any tips on the error code, nor could I find any forums with a similar issue either. From looking at these forums, it looks like Samsung is prone to have bad pico-fuses on their T-Boards but I am not sure if that is where I should start?

Any help is appreciated. Thanks!

Any photo's of the panels and panel layouts showing connectors and legends?

I do believe this to be plasma(correct?) so there is no T-con board.
Lot's of 60" and 64" plasma's from samsung suffer from bad solder joints on the power supply.Take a good look at all the components on the heatsinks. Sometimes it's really hard to see if they are cracked or not.

You are likely correct as I was looking for the T-board and couldn't really find one.

What kind of bad solder joints? I used to work with consoles and know most cold solder joints on ICs can't really be found with a naked eye and could need a reflow/rework done on them.

I took a look and most of the components mounted to the heatsinks on the power board are covered in a silicone glue, so I am not able to see the connections. The ones I can see, seem to be fine.

Thanks

Did you take out the powersupply and look at the solder side?

I did look at it initially and nothing appeared out of place. I just rechecked it and took pictures and I don't personally see anything without much reason. As I have seen a lot worse soldering jobs done and work fine..

Slightly off topic but would appreciate your answers.
What is the part which is in the red box.

Have you checked to see what supplies come up and if any do not?

i think you will find this is a Samsung Bluetooth Module

Look on the power supply firstly you will have VS/VA test points measure them to see what you get they should match up with your panel sticker voltages

Thanks very much for the information. Much appreciated.

Why on Earth--is there a cap hanging off that board instead of being fitted correctly!
--recipe for disaster, that!

That is the capacitor I had suspected beforehand. The only replacement I could find was >x2 the Voltage and does not fit around the caps that were near it originally. So I ran a small bit of wire and used heat wrap to cover the leads of the cap to prevent arching or etc.

I will skim that thread a bit more in a little, but did not see anything to deal with my error code/problem.

Let me go ahead and check.

--VS--
Actual: 221.8
Rated: 219.0

--VA--
Actual: 55.1
Rated: 55.0

Since I believe these are within reason, and no signs of blown caps, should I assume the power board is fine?

Edit: I should also mention that since I owned the TV (for the 2 weeks it worked), it would intermittently go black and then go back to the picture and say "HDMI2" or etc. I didn't think much of it before, as I figured it was either my HTPC or the HDMI cord bottling the throughput, but now I realize that could mean T-sys board too?

Edit 2: I was checking the VSC and it was about 10v off. Then the TV turned off like it has been doing. I then retested the VS/VA and it was something like 70v/10v, respectfully.. Not sure what to make of this personally.

--Bump--

I would be willing to donate some coin if someone can help. Just annoying having a 60" broken and using a 30" as a temp

Behind the black plastic part for the stand is another board,the logic board,can we get a close up picture from that? Wanna see if we can get it to run the test patterns.

And maybe swap out that wired cap for the good of Alastairs blood pressure

Attached is the main board. And I will go ahead and order a replacement capacitor
