Re: samsung un58tu7000u bootloop and no display
just to let you guys know the VGH on left side of the panel was short.
how i know...i cut all the vgh,sk1-sk8 and other test point on the panel board
then i tried connect VGH first by solder...and that bloody thing was short tv start bootloop..that circut is bloody small to track where VGH goes . so i call it a day and junk the tv in store to ROT.....

Re: samsung un58tu7000u bootloop and no display
well i have done all those trail and error hours and i reach up to this point .. the videos on youtube are not specific to this model and few are there but language barrier..
the thing is i want to know these negative voltages i am getting on all test point excpt the VGH is very odd and i want to know why.
can someone tell me why all are negative readings...Leave a comment:

Re: samsung un58tu7000u bootloop and no display
well i am an aircraft engineer type of Nerd.. anyhow that is not important ... yes i check all the capacitor on the panel with multimeter .one side is grounded and other side show not grounded so that are all ok.. To me the voltages look not ok... all negative except VGH.
the screen no display and just lines seems like something wrong with voltages. I downloaded the panel datasheet from the this forum CC580PV6D and as you can see the pin which i masked in pin no.28 ,which as per datasheet is VGH2....Leave a comment:

Re: samsung un58tu7000u bootloop and no display
just an update to previous post i forget to mention the voltages
here are the voltages on both side of the panel both sides
1. ck1-ck8 = -6v dc
2.clr,stv,vss,lc1,lc2 =-6vdc
3. vgh = +24vdc
i dnt know what extacly these voltages are meant to be and the values.
any expert can helpLeave a comment:

samsung un58tu7000u bootloop and no display
HI everyone , I have this samsung un58tu7000u tv with boot loop . i been reading all these threads regarding boot loop and i managed to get the screen show now vertical bars but no solid image.
The tv came to me with no image and boot loop

1. I remove PSB input to MB ,the backlights are working fine ,no boot loop
2.Connected PSB input to MB ,boot looping
3.Disconnected the flexi cable from MB to panel input , no boot loop
4.Connected the flexi cable and removed the U shape flexi cable on panel pcb to isolate right side... -
