Re: 55EC930V white vertical line appeared (need help)
One thing I know is to block the protection pin on LVDS cable, tv could Start again but will not fix any screen issue (in this case a vertical line how you said.
You have to look at the service manuel, when I remember the name was something like "burnt_det"

Re: LG 55EC930V OLED - 3 Second Power No Display
Ok when the LG Logo stays illuminated then TV is powered up. if i remember you had to press exit with normal remote and then power off TV. in-stop should work too after pressing exit when TV started with bright LG Logo. can you try again?Leave a comment:

Re: LG 55EC930V OLED - 3 Second Power No Display
It was the screen, i had a thread in this forum and we tested it.
forced panel on and half screen side was dark. it's sad because it was a expensive TV for these 4 years.
@tmaster21 ahh, sad to see your screen defective.. :/ but you can bypass it, to turn the tv on with broken panel. on the LVDS there is a pin "BURNT DET", i blocked this pin and then i could start the normally, then i saw on my tv the loading screen two seconds with stripes, then screen went black.
here is service...Last edited by TeslaMichael; 11-04-2022, 04:08 AM.Leave a comment:

Use RCoid App and download in app LG Service remote. This worked well with my old galaxy s5 and 55ec930v
BTW. Disconnect LVDS cable and TV should turn on or it's a MB Or A Psu issueLeave a comment:

Re: Oled cof tab bond Q&A
I tried opening the panel (55ec930v) long time ago and i was very careful but then panel cracked. I got also some images that I can post tomorrow. I would say it is almost impossible to open panel.Leave a comment:

Re: LG 55EC930V won't turn on
Oh okay, my OLED had this same issue. At the end it was a panel problem.
But it doesn't mean that your tv has also faulty panel. Sometimes mainboards fails too.Leave a comment:

Re: LG 55EC930V won't turn on
This is a OLED, this set doesn't have LED backlights.
Do you have a Service remote or old phone with IR sensor ?Leave a comment:

Re: LG 55EC930v is not turning on, it's dead
Project is over.
i did test with my T-con again and the replacement T-con. this t-con had issue if you remember that there was a white line on left side going down with the replacement t-con. if it reached the end of the screen, right side went bit brighter with freezed horizontal lines.
left side was bright.
i was 40 cm away from left side and i feeled the air gets hotter. i touched it and HOLY SHIT was this hot!!!
measured 86°c!! after one minute.
Want to thank all here for helping... it...Leave a comment:

Re: LG 55EC930v is not turning on, it's dead
And the another weird thing is now, TV is now always turning on with normal remote and i see everything flickering. then also the loading image and then everything is away on screen and i see on left side a bit green, also a bit of these green lines i got when LVDS removed.. and also hearing sounds in the corner like buzzing..
unfortunately i didn't shot a image of the cabling..
It's time to give up...Leave a comment:

Re: LG 55EC930v is not turning on, it's dead
I will try this tomorrow, then i will have more time.
And when putting jumper in place, i won't get a electric shock of rest power from PSU? i remember that condensators save voltages for a small time.
and i looked around the forum again and found one thread with exactly same issue, what i'm seeing on my tv. name of the thread: " Default Re: Need help testing an OLED TV | LG 55EC9300 "
Then it's sure the same thing like in the other topic but i should try it anways.
I should add also, that i'm hearing...Last edited by TeslaMichael; 01-15-2022, 02:03 PM.Leave a comment:

Re: LG 55EC930v is not turning on, it's dead
I mean, there are different mainboards avaible for the TV. but on this image, it's my MB.
I can't find a red lamp when TV is on. that's what i mean. you marked it with LD, but there isn't something glowing. Is this a lamp on my MB?
I checked again LVDS cable and one pin is loosing signal if cable is moved. beeps, then nothing, beeps, again no beep and again all the same.Last edited by TeslaMichael; 01-15-2022, 11:59 AM.Leave a comment:
