black neg. lead in com, red pos. lead in V. might not want to measure anything that might be over 300 volts with that meter but you can still check a lot of stuff with it.

That's right, for checking the voltage. But for the capacitors, is it right to do like in the picture?
For the voltage check I am afraid you will have to tell me what and where to check after I will provide the photo of the boards if that's alright. I usually look to check for fuse on the pcb , but I couldn't find one.

you can check caps with the same setting of V, just not sure I would check the main filter caps on powerboard with that meter, they usually are around 400 volts when tv working.

fuse on powerboard is ok, could check on mainboard, sometimes theres a bunch of little fuses that you can check on some mainboards, they will be labeled starting with a Fxx, if they're labeled.

Is this the right way to do it? Please check the picture
I know that if the caps beeps when I use the multimeter, in most occasions its a bad capacitor.
I also know that if I set the multimeter to 20k to check the ohms and the value is not going from 0 to higher, that's also a bad cap.
Correct / guide me if I am wrong please. Thanks

yes, this I call a dirty test but I have found bad caps this way, if you have some caps that size it sure shouldn't hurt to go ahead and change them out.

You can try taping pins on lvds cable going to panel to see if you get any sort of picture.

It’s a trial and error kinda of thing. So might have to try several times covering different pins

Thanks for the reply. I will have to try this, but is this the case? I am asking because, if I remove the big white lvds cable nothing changes, so I guess the CSF01 ( ribbon cables) might not be the problem.

Hi pal. Thanks for replying.
I have tried that using a cotton bud and gently going over every bit of lvds/ribbon cable existed, going from left to right and so on.

Turned off the tv. Lvds plugged in. Removed the left U ribbon cable, nothing changed, turned the tv on, no change.
I did the same with the right side of the first U ribbon cable, same result.
Again, I did the same with the right side U ribbon cabble, following the same steps, no results.

Sorry, blue screen 4/4 . If I press the channel button on the remote I can see the blue screen going darker and light again, as if changing the channels normally, if that makes any sense

in this case... take out the LVDS and with yours mobile camera or magnifier inspect all pins.. you have one or more from one side or both cut out short ..

LVDS, the white long cable coming from the PCB to the CSF01 ribbon cable, yes? Where should I look? Along the length of it?

Re: Samsung 65" UE65TU7000KXXU VER:02/UTU7000 TV Blue screen

Re: Samsung 65" UE65TU7000KXXU VER:02/UTU7000 TV Blue screen

in case the LVDS all PIns are fine same long.. no one short than others.... then put it back carfully..... put the TV in stand by by remote.... after TV in standby mode push with remot this pne afte other
INFO --- MENU-- MUTE--- POWER ( this is service menu = in case it show to you service menu.... dont do any things just plug it out from wall socket... same case if the screen show blue..... just plug it out from walll and try again..
its possible because the first time you put U ribbon not correct.... the MB change mode... hope this will help.

Thanks dude ! I will definitely try this now. By the way , if I cast YouTube from phone to tv, the music starts so I think this source should have worked , right?
