Samsung UE55JU6000K stuck at 'Setup Conplete'

[notallbad]

Reset the tv as internet connection not working, connected to router but no internet.

Did a factory reset and completed the initial setup process but now just freezes on 'Setup Complete' page.

Going into service menu it says 'Failure' at the top of the page and unable to access the 'control' screen.

Its already on T-HKM6DEUC1570.0 fw.
Are the SVC reset options likely to help here?
options are
apps reset
svc reset
spi flash reset
data sync reset
Any help appreciated.

Are you trying it with an ethernet cable, it can be easier trying it with ethernet, then if it works, you know it's something to do with the wifi.

Wonder if samsung quit supporting the apps etc. on this tv.

I would just try a factory reset, that might help.

Maybe something like this: Press the Menu button.
Select Support, then Enter.
Choose Self Diagnosis, then Enter.
Select Reset, then Enter.
Enter your Security PIN. The default PIN is 0000. The default PIN code is 0000. ...
Tap Yes to confirm factory reset.

Cant access menu as its stuck at 'Setup complete' page.

Am currently waiting for main board to cool down, possibly hot, to try again once cooled down as could be a fw/hw issue, namely a corrupt chip.

Well, seems it wont start up now, just 5 red blinks.

Shall look for a replacement main I think.

I do know the backlights need changing as some lenses have fallen off and rattling around inside plus there are bright spots and some have a blue tinge so shall order some backlights too.

Just as a note for anyone that comes across this later for help I have also disconnected the panel one side at a time, then both, then t-con from main but still 5 red flashes, no backlight, no image. Oh yh and only getting 1 static blue light on the t-con board, not sure but possibly
should be 2. Actually there are 2 static blue leds on tcon, 1 is under the heat shield plate.

Disconnect main from psu and get backlights come on.

For reference the red standby light comes on from power being applied, then press remote on button. 5 red slow flashes then goes back to red standby then 5 red flashes, cycle continues.
Just to be clear its not 6 red flashes.

I did manage to do the apps reset and svc reset in service menu with a 'success' message but didnt get chance to do the spi flash or data sync resets before the dreaded 5 red flash.

I suspect the main, possibly tcon too, needs replacing as owner said tv not working as it should, I had difficulty getting internet connection, freezing/locking up on factory reset so looking likely.

Heres some voltage readings.

If I remember, shall do the same again with new led strips and again with replacement main.

Re: Samsung UE55JU6000K stuck at 'Setup Conplete'

Anyone know if its necessary to pair the main and tcon?

Would I need to do anything else other than just replacing the main or is it plug n play?

Just the main replaced and now working again though still waiting for backlights.
It has exactly the same boot sequence, 5 red flashes and both tcon blue static leds.

So looks very likely it was corrupt fw or faulty chip.

Comparing the voltages the only difference is blu_pwm 0.46v this is with backlight set at 12 whereas set to max 20 it reads 0.5v.
od-on/off is 0.3v lower but dont think this is of significance.
