Re: LG 65UH5500-UA common problem?

NOT this, on the board... take out the speaker and the metal cover of the effected side.. see are there U ribbon cable as its 65 it may have 2 or 3.. many UHD used U ribbon.. hope yours too

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.

Re: LG 65UH5500-UA common problem?

i don't think this pin the problem, see the tab of the effected side.. you may have U ribbon cable on it.. if yes then its just fitting it again,

by tab do you mean the tab connecting it to the glass panel?

Swap the ribbon and let us know the results, of course only one half of the panel with work but at least it will put your mind at rest knowing its as simple as replacing the ribbon.

We're all waiting in suspense!

ahhh have to work up the courage to swap from the working side to test. the guy from ebay shipped today hopefully those come in soon!

Re: LG 65UH5500-UA common problem?

have to take off the plastic frame and "metal bar" on the bottom of the tv by driver board and then the panel just lifts up, if that makes sense.

After writing that realised the OP has already disassembled his to replace leds. So already knows how to do it.

Re: LG 65UH5500-UA common problem?

I guess you came across this tv cheap or free, so don't know the history. So its possible the fault was already there before you attempted the led repair.

I have my fingers crossed for you, hoping its just the ribbon.

Re: LG 65UH5500-UA common problem?

Hope all goes well!

Does the panel have to be lifted from the top on these sets or can the casing be lifted away from the panel?

Perhaps start your own thread giving a guide on how to disassembly just in case this guy needs to know how to do it, he is a noob so any guidance will be appreciated, I'm sure. But he only really needs to expose the tabs on the panel.

Re: LG 65UH5500-UA common problem?

About to repair the led backlight on the same set. I ruined my last 65" by being impatient if I screw this up I can put the ribbons in the mail for you.

That being said, don't jinx me. lol

you're going to be fine! if I can do it, you can deffffff do it

overall wasn't too bad i mainly followed shopjimmy's vid

good luck!

Re: LG 65UH5500-UA common problem?

Can you swap the ribbons over. If the fault moves with it then it's a ribbon problem.

Was worried about messing up the other ribbon, so didn't try it. Maybe I will just have to.

Re: LG 65UH5500-UA common problem?

yh, the actual tv power plug.

Lift the speaker off and inspect the tab bond to see if you can see any obvious damage and compare to the others. But usually damage is at the panel side which will not be visible until exposed by removing the front case/shell and even then it may not be obvious that the tab is not properly bonded, not advised to check this just yet.

Wonder how the ribbon pin got damaged? Someone attempting testing/repair before perhaps.

Also check the connector it plugs into, both ends in case the ribbon has been switched around but they are both connected the same way up in photo. Do the pins all look straight and even?

I might have damaged the ribbon when I tried to connect it back. I had to unplug both of the ribbons from the driver board when I replaced the led strips. And then maybe when I put everything back and plugged the ribbons back into the driver board I might have bent that one? Not sure...

Re: LG 65UH5500-UA common problem?

There is hope for the OP here then, thats good.

But do check the connector pins look to be in good shape and not damaged as the ribbon pin is damaged for some reason yet unknown?

Be absolutely sure to match the ends of the new and old ribbons to confirm pin pitch is identical, probably 0.5mm pitch.

Re: LG 65UH5500-UA common problem?

I think that bad pin is the problem, looks like it's at the end of the connector where the fault appears on the screen, sometimes you can do surgery on them by trimming off the ends but prolly better to just get a replacement ribbon cable.

Re: LG 65UH5500-UA common problem?

Wonder if anyoneone else would like to jump in here with there vast knowledge.
I'm not sure that one pin being disconnected from the ribbon would cause your problem but could be wrong, possible it depends what signal that one pin has on it?

But swap it over or replace anyway just to see.
