LG 55EC930v is not turning on, it's dead
Hello!
First i want to say, i have no experience with Electric repair, and because of this, i'm very carefully. And my English is not the best, because I'm from germany, but i try my best.
I'm 6 months already here in this forum, because the TV of my dad isn't working anymore. It's the 55EC930v.
I readed almost every thread about this TV here, and i saw already some things like image tests and other tests.
I saw also something with IR Blasters, and i tried it. i have still a old galaxy S5 with IR Blaster, and got a App with the "Power Only" button.
was before happend: we were out of the room, tv is alone in the room, it was on. then we came back 5 minutes later, and the tv is off. But this happend already once, but he could start again.
Ok, then my dad wanted to turn it on again, but then it just give a click and after 2-3 seconds another click. The LG logo is on, but it's going darker and brighter.
Then we just opend the TV, and there was a lot dust inside.
We cleaned, looked at the parts, and first look was ok.
My vater used contact spray.
Tried again to turn on TV, and still nothing, same problem.
Then removed the T-Con and looked at it.
it was ok for me.
Then my dad got another TV, and then put the broken LG in the basement, because he didn't wanted to look again at it, because it was expensive and was working only 4 years.
Then my grandma said, she want's to repair it, and i could bring the tv to her this week.
I opened it, and looked at the parts again.
Then i removed a cable from the T-Con and i got for 2 seconds a half dark screen, it was like grey, but in the camera you clearly see, it was green.
Then i removed another cable from T-Con, and saw it very bright with green Color, and also burn in. Maybe because i removed the LVDS cable??
I removed once all Cables from T-Con, and LVDS too, and it didn't came on. Used Power only on galaxy S5, and the LG remote.
Then i removed completly the T-con, and tried it again, but same problem.
But if one Cable was removed, then it took maybe 4-5 Seconds, until the tv clicks again after the first click.
And i connected every cable again and put the tv on another table and said to me, i'm done. But then i tried again to turn it on, and i saw on the left corner some lines moving for 2 seconds, until tv clicks again.
I also tested the USB slots, and two of them are working for half second, i plugged in my phone and a PC mouse.
the third usb slot isn't giving a feedback, Nothing.
My grandma want to call a technican tomorrow, that should look for the tv, what is wrong or broken.
I wanted to ask here already, what it could be, and i think the mainboard is still in proction mode, or it's maybe broken?
I added some images from the TV.
I'm already exciting what you say.
Best regards,
Michael
