Re: LG OLED C7P55 - keep turning off after 15-30 seconds.



Hi, thank you for replying so soon.

I checked to see if LG has any updates for this TV through their menu (ABOUT TV). It looks like the firmware it is currently on is the latest version.

I will continue to use it as you advised. I will provide an update tomorrow or when the problem resurfaces again. But it looks like it is working for now! Thank you for everything....

Re: LG OLED C7P55 - keep turning off after 15-30 seconds.



UPDATE: It just started working! I don't know how or why, but it began working. I turned it on and expected to quickly go through the initial setup process after the factory reset, but it continued to work. However, since this has happened a couple of times now, do you have any suggestions for preventing it from happening again or this issue resurfacing? My current firmware is 6.10.30. I heard there might be some firmware or something similar available for download on the LG website that can be updated on the...

Hello Diah, thank you for your reply and support throughout this process. I tried your method a couple of times today, but it hasn't worked its magic yet. The TV is still suffering from the same issue. I will continue to try out the method and monitor the results. Just to clarify, when you said "finger click on the screen surface," do you mean to tap on the screen or make a firm press on the screen? I did try both ways, but it hasn't shown any results, so maybe it isn't a difference maker.

Hello, thank you for your reply. So, as you pointed out, I did, of course, screwed everything in. I used my voltmeter to check which one of the two wires is 24V and which one is 12V. I can confirm that the black wire is 24V while the white wire is 12V.

I waited for about 10 minutes with the TV on (with the 12V plugged in, not the 24V) before plugging in the 24V wire into the T-CON while the TV was still ON. The TV was in screen saver mode, but unfortunately, it turned off in about 30 seconds....

Sound and screen work while it is on.

I attempted to troubleshoot the power cable by unplugging it and pressing the power button for 10-30 seconds before trying to turn it on again. However, the problem persists.

I removed the back cover and tried replacing the power board, but the problem did not get fixed. Although, for a brief moment, it seemed like the issue was resolved as the TV stayed on for 5 minutes before reverting to turning off after 15-30 seconds.

I attempted to replace the T-CON board, but each time I turn the TV on with a new T-Con board,...
