Re: LG OLED55B7V doesn't turn on Help.
ho. I changed. TCon board.
got one used today from damaged screen. The seller claims that it must work because the TV turned on when the screen was broken... it looks like I will have to buy another main motherboard.
what do you think?

i tried covered lines.. exactly as you wrote. first 3 lines.. it was not ok..
tried covering only 1 line on the far right on the right flat cable. blo is better, but still annoying. the upper part of the screen still has lines.

Philips 58PUS7505/12 Backlight OK / no picture.. Help
overnight my philips is 2 years old but unfortunately it is no longer under warranty.. started joking..
the picture became black.. but the next day when I turned it on, I still saw a little something... But now it's just black..
the backlight works normally.. the sound too.. the motherboard also shows that it is ok..
I suspect a T-Con panel. Do you think the panel is shorted?
below I am sending you a video about my TV and how it behaves.
I also tried disconnecting the ribbon cables. first the left one, then the right one.. but I can't find out if the panel has... -

Re: LGOLED55B7V Clicking and dead screen.
Hi Donny2derby
would you sell me the main board ?? and T-Con.. if it still works of course..
I have a similar case, but I have a fault with either the Tcon or the main board.. you can read my post above...

Re: LG OLED55B7V doesn't turn on Help.
I apologize. in this last step that you wrote me, I don't understand the process of how and when I have to press in_stop.
the 24v connector must be on or not??
and what code are you talking about??? I have an LG service remote.Leave a comment:

Re: LG OLED55B7V doesn't turn on Help.
i was watching the screen.. through the mirror i had set up for myself.
nothing happens, not even a hundredth of a second, no lines appear, nothing.
it just sparks on the 28 pin connector when I plug it in and within 2 seconds it goes back to standbyLeave a comment:

Re: LG OLED55B7V doesn't turn on Help.
I did exactly that. Turned on tv, optical port lit red, with tcon disconnected from power board and plugged it in after a couple minutes and the tv just powers off (standby) with optical red light off and nothing on screen. Tried 5 times already.Leave a comment:

Re: LG OLED55B7V doesn't turn on Help.
It lasts for 5 seconds only if the tcon is connected to the main board.. if I disconnect the 1 lower lvds cable that goes to the main board, then the TV turns on.Leave a comment:

Re: LG OLED55B7V doesn't turn on Help.
all voltages are present for 5 seconds..
but if I disconnect the 2 LVDS cables that go from the T-Con to the green main board, then things change.
the tv turns on, all the voltages are present... the red light flashes when I press the remote. for example volume UP/Down... and the light on the optical connector also lights upLeave a comment:

Re: LG OLED55B7V doesn't turn on Help.
after all, we are talking about OLED panels, not LEDs.... so the backlight does not exist on my TVLeave a comment:

LG OLED55B7V doesn't turn on Help.
Hi.
namely, the TV stayed turned off at the red light overnight.. when I want to turn it on with the remote or physical button, there is a not relay click.. and after 5 seconds a click back. the light is always on, nothing flashes... I opened the TV and played around a bit.. when I disconnected the flat cables that lead from the T-Con of the board to the main board, the TV behaves differently (normally) the red light flashes 3 times and then disappears... the TV remains on.. on the main board the audio output light also lights up. and when I press the buttons on the remote, the light...Last edited by markolino; 09-12-2023, 03:16 AM. -
