Re: LG OLED65C9PUA no audio/video after delicate move
ya, I opened a ticket with the Google Fiber. It's going to take a bit of time to resolve, especially with the holidays. I'll update as it progresses.
Thanks so much for your help. I've seen your posts as I searched the forums for a resolution and prayed that you would respond to my thread when I decided to make it after not finding a direct solution. You're a great help and amazing resource to the forum!...

Re: LG OLED65C9PUA no audio/video after delicate move
In post #8 you said "unless you hit the front of the panel within your transport"
Is this only G & B symptom indicative of a pressure on the front of the panel with no cracks or marks?
I had a Google Fiber technician in my house while my OLED TV was in the box lying on the floor and he set his bag on the box. I quickly told him to take it off. The TV was in a Home Depot TV box with padding and a blanket so there's no markings from it, but I'm not sure how much his bag wei...Last edited by Xavier847; 12-22-2021, 08:23 AM.Leave a comment:

Re: LG OLED65C9PUA no audio/video after delicate move
Ok, gently rocking the cable every so slightly has me teetering between having a full screen image with the yellow line or shutting down....Leave a comment:

Re: LG OLED65C9PUA no audio/video after delicate move
Ok, so I was reading a SONY TCON troubleshooting pdf and came across the advice of loosening the LVDS cable and to "gently rock the cable in and out of the connector" looking for a response. It turned out to be the bottom(closest to the 4 ribbon cables that connect to the panel) LVDS cable that causes the TV to shutdown, so I gently put in one corner and started rocking the other end in and came up with this image below. It's essentially the setup screen squished and repeated 4 times. If I plug that bottom LVDS cable...Leave a comment:

Cool, I just ordered a TCON board from tvpartstoday.com. I'm thinking this could be the resolution. I'll remove the TCON board this evening and check it out....Leave a comment:

Re: LG OLED65C9PUA no audio/video after delicate move
I just read that TCON boards are married to the panel and are not able to be used with other panels. Do you have experience with swapping TCON boards on LG OLEDs?...Leave a comment:

Re: LG OLED65C9PUA no audio/video after delicate move
Ok, I was able to get IN_STOP to factory reset the TV with 0413 code. When I turn it back on without the 22V TCON connection, I get the audio for the setup menu "Please press OK wheel button on your remote." When I plug the 22V cable back in, the screen flashes the yellow line and then shuts off. Does this mean the module/panel is bad?
EDIT: With everything plugged in except the LVDS cables, I'm able to get the setup audio "Please press OK wheel..." as well as the vertical yellow...Last edited by Xavier847; 12-19-2021, 08:49 PM.Leave a comment:

Re: LG OLED65C9PUA no audio/video after delicate move
Ok, so I followed these instructions and on step 3 it powered on with a black screen, red light in the optical port. I tried getting sound from the HDMI1 port with my PS5 plugged in but no audio at all. Then when I plugged the 22V cable back into the TCON board the Yellow line flickered and then the TV shut off.
Does this mean that the Mainboard is working and the TCON board is broken? If so, can I replace just the TCON board?...Leave a comment:

Re: LG OLED65C9PUA no audio/video after delicate move
So, I took a closer look at the LVDS cables and ports and didn't find anything obviously wrong with either. I'm curious if it could either be the TCON board or the Mainboard that could be the issue.
When I moved this time, I left the 2 vertical VESA mounts attached and used those those to handle the TV most of the time because I thought they were the most secure anchor points on the panel. I'm wondering if handling it from there might have caused any issue....Leave a comment:

Re: LG OLED65C9PUA no audio/video after delicate move
THANK YOU! I was so careful with moving it that I couldn't believe it was a panel issue. I'll look over the 2 LVDS cables and ports....Leave a comment:

Re: LG OLED65C9PUA no audio/video after delicate move
Hmmmm, unplugging the LVDS cables prevents it from shutting down but I'm still not getting an image on the screen. Do you think that Vertical Yellow line is indicative a broken panel?
Do you think I just need to get a new TV?...Last edited by Xavier847; 12-15-2021, 10:42 PM.Leave a comment:

Re: LG OLED65C9PUA no audio/video after delicate move
So, here's some pictures of what I'm dealing with.
If I unplug the 2 ribbon cables from the mainboard to the T-Con(middle board I'm assuming) board, the image persists on the screen without auto shutting off. So the yellow line persists when all 4 of the bottom ribbon cables are plugged in. The Green banding is what persists when I unplug the outer 2 ribbon cables across the bottom of the T-Con(?) board. The last image shows this scenario.
Different combinations of bottom ribbon cables give slightly...Leave a comment:

LG OLED65C9PUA no audio/video after delicate move
I moved about 2 months ago and am just now getting to troubleshooting my OLED TV. I've owned it for well over a year now and have never had a problem. I bought it lightly used and even moved it across state lines, so I'm confident in the 8 mile move I went through 2 months ago.
The issue I'm having now is that when I turn it on, there's no audio or video except for quick flash of a vertical yellow line in almost the exact center when turned on. I can hear a solenoid like click when I power it on, then after the brief .5 second flash of the vertical line and 5 seconds of no response... -
