Re: LG 65UH5500-UA common problem?
There are no U ribbons that I can see. Only those 2 ribbons I showed and another ribbon that is not attached to the glass panel.
Even after removing everything when changing the LED strips, there were no other ribbons besides the ones seen here. Moved the speakers in this pic.Attached FilesComment

Re: LG 65UH5500-UA common problem?
Just tried switching the ribbon from the side that was working to the defective side and same result
I will try messing with the U-ribbon on the side that is defective.
Hope it works.
I should probably return the ribbons I ordered from ebay then right?Comment

Re: LG 65UH5500-UA common problem?
Here is the U ribbon of the defective side, how can I seat it correctly? It looks to be in properly, I never took them out when replacing the LEDs.Attached FilesComment

Re: LG 65UH5500-UA common problem?
you need to provide a better picture of the bottom edge board on the side showing the gray vertical bar so the forum can see how that side is interconnected. As pointed out, the "U" ribbon cables interconnect the bottom edge boards to complete the drive paths. However, on sets of this size, there may also be side tabs and / or side edge boards (similar to the bottom one) that also might have some interconnect cabling.
further as a test, you can disconnect the "u" cable on the "bad" side, you should then see about 1/4 quarter of the picture go white (or black) depending on design... including the grey area should be "gone".Last edited by budwich; 05-07-2020, 04:42 PM.Comment

Re: LG 65UH5500-UA common problem?
Oh man, think I just found the culprit
Removed the tape to see the driver board on the defective side and about 3/4 of that tab is lift off the board.
Is there anyway to fix this or am I a goner?Attached FilesComment

Re: LG 65UH5500-UA common problem?
what ever you do, don't take it any further off as right now it is basically holding "alignment"... you might get lucky by very carefully cleaning what you can and possibly holding it back down with something.Comment

As stated by the person I collected the TV from, it just stopped working overnight. However, I still gave it a go to try and repair it.
There is a thread on the same TV but with slightly different issues where they had to tape connection points on the ribbon cable, so I want to see if this is repairable by any chance.
After bringing it home and plugging it in, the TV turned on with its backlight working but had no picture. After removing the back cover, the first thing I tried is to unplug one of the ribbon cables and the situation is as follows.

Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.
The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.
Original T-con:
Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.
First replacement T-con:
I thought it might be t-con and ordered new t-con from china(supposedly tested)... -
So i have a samsung un65nu6900f in for service. Its doing the power cycle 2 blinks thing. Many other people have worked around this by taping the LVDS cable at the expense of losing some color quality on the affected side of the panel.
My customer is not super happy about that compromise so i spent all day tracing this thing out today. I can confirm that the issue is not related to the clock signals, but rather the VGH signal right next to them. It is supposed to be 25V, it is 0v while the whole cycling thing is happening. If i remove R13246 from the main board the tv will power... -
This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode... -
Hey there,
So I got a problem with my LG OLED TV (OLED55B8PLA).
the problem is that the tv won‘t power on some times, the led stays red and won‘t even blink, just solid red when I try to turn it on. USB devices connected won‘t light up. 1/4 of the screen (left side) shows some green „clouds“ that are getting brighter everytime I turn the tv on and after some tries the tv finally turns on. Sometimes it takes 10 tries and some times 100 or even more tries.
When the tv is on, everything works fine, hdmi outputs, usb inputs, wifi, bluetooth, etc is working...
