the OLED is dead but we have all the parts

[@michaelhawthorne8696]

OMG... I work in a company who is nuts about Static damage and Wrist bands and Mats are always used and checked weekly....for good reason too. Wouldn't want to have an Airplane fall out of the Sky due to a partially killed PCB from Static damage. The guy sending you these boards obviously knows nothing about ESD precautions. The Bubble wrap could have done untold damage to all the boards. You need to get rid of that carpet on your test bench too and only have a piece just to protect the screen....the surrounding area should not be carpeted.....Boards placed on these areas could suffer too.

You don't know if the bubble wrap killed the motherboard ... It should be placed in an anti static bag to protect it ...

[@mikecassap]

Just checked something Allen if you power the setup and you hear a relay click and standby light flashes once that means the main board is good . now check power rails for the 24 volts and the 12 volt rail then unplug both tecon cables and check voltage rails again if both rails ok then it’s the main panel fault mate

[@sajjadmughal308]

This is the only way to check oled tvs mother board power supply and panels but in some cases t con board has short smd caps on 22v line.must check t con for shorts before replacing the panel.

[@wisher21uk]

Unlucky Allen I would check the fuses on the driver board, there’s normally 1 where the power comes from the main board and 1 where the 24v from the PSU plugs in 😊

[@marin6810]

Allen, maybe it would be worth to plug in speaker plug and try again. I had strange issues with one led tv when speaker plug wasn't plugged properly.

[@PaulSamps-gf6yz]

Thankyou for high lighting the need to tighten the screws on my Panasonic plasma. They were loose so i was on borrowed time 👍

[@Jimmyspangle]

Seriously, take a step back and put on your technicians hat and start with good old fashioned analysis in a logical order. This went from that into the realm of wobbling random plugs and guessing which board may have failed. You are better than that and I think you can get this working of you start over. Best of luck If you can't fix it, send it to me and I will get the thing up and running.

[@georgeprout42]

I can see a "smashed screen" TV being a consequence of a board/backlights failure leading to the owner throwing something at it in anger. Probably comes with a broken remote control as well.

[@welshminty]

OLED screen will not power on without an input signal to prevent burn in. Supply it with a test HDMI signal OR press the menu button on the remote to bring the screen out of power save.

[@ciarayboydj]

All those OLED failures are giving me the fear! I have a 2020 LG CX. So far it's been faultless...

[@jerrymcg3199]

Hope those boards aren't static-sensitive

[@paulwarner5395]

Was wondering that seeing them wrapped in bubble wrap.

[@BertGraef]

yes they are. Should actually use a static bag and wear a hand strap , or touch some metal occasionally while working on anything electronic . Gets much worse in winter when there is low humidity, or if you do much walking on carpets. You learn the hard way. 5 volt stuff doesnt like 50000 volts going through it.

[@shawnstthomas4811]

You may have to get the LG WAV file to play the in start through an infrared receiver or get the service remote to the in start because oled main board will shut down and go into protect mode if it came from an OLED with a cracked screen I have seen this before

[@alyoshapearce5985]

My method to repairing things like this is to throw it in the trash and buy a brand-new one. It’s fixed perfectly then.. plus you get all the new features and better UI to boot.

Check for shorted smd caps on the tcon board.. common fault on these sets

[@ford1546]

If the oled picture is too bright then turn down the brightness, and you will extend the life of the oled panel oled has its own light just like plasma tv has. oled is in a way an improved plasma tv since both do the same thing in practice to display the picture. You won't get better black and contrast than what oled gives!

[@EastAngliaUK]

I was given a little sandstrom tv 24 inch tv with DVD the other day but the speakers don't go. but if I plug an aux into headphones sound works.

[@G-ra-ha-m]

Maybe a small 'bluetooth' speaker can be plugged in?

[@alanr585]

Yes, remember the standby light lit means it's in standby and no standby light means it's on but with no signal, the screen wouldn't light unless there is a signal but you did check with the remote for a menu with the second board and that shound have showed something. Oh ok, looking back,, you have one so you know that. I enjoy watching your channel, I repaired tv and radio and everything else in that field since the sixties and got out as plasma started.

[@chriswilson7493]

Err, didn't you put the original board back in after the first swap over? Forgive me if I am totally wrong 😁

[@borisdg]

It's actually important, beacuse all the OLED panel data is written there - aka if you ran pixel refresher, the voltages for each pixel are recorded, so you get picture with no banding...

[@linfield2012]

I would have tried an input if only to check audio.

[@site22s22]

Anisotropic Conductive ACF Film that is used to connect ribbons to screen had exactly the same issue on an OLED after sourcing another unit to scavenge a board set from nailed it down to ACF film

Hi Allen, have you tried isolating a few boards to see if backlights come on voltage checks on power board, missing power rails? etc . might be a process of elimination Back to the basics👍🇦🇺

I won a 65" Samsung OLED S90C from a local grocery store drawing. The picture is quite stunning, but I still tend to favor my 54" Panasonic plasma TC-P54V10 Viera (15 years old) for many aspects. I would assume you had already checked the voltages coming from the power supply in part one, but a recheck might reveal the problem. There might be one missing or low. Also, many times a solution will come to me in the middle of the night when I'm half way asleep.

[@PcGamingForFun]

in what aspect do you prefer the plasma!?

[@douglashoff95]

To me the color is more accurate. Putting them side to side the plasma set looks more natural. But the Panasonic was a top of the line set and the OLED is second down from the top, so the Panasonic has better processing circuitry.

[@stepheng8779]

​@@PcGamingForFun Still using my Pioneer Kuro, I'll take over any new TV out there. Colour, motion, upscaling. Sure it only goes up to 1080 but I'll take its 1080 performance over any 4K

[@Animal_lives_matter]

I guess one more thing to try is the power board? I'm guessing you tested that already and would be a waste of time and money. It's probably the panel, or a longshot, could it be a cable/connector fault? I've wondered if cables can degrade over time with heat. I've had a lot of trouble with USB cables and connectors recently that got me thinking. I've got an old Samsung plasma that I'm trying to fix. It's great for retro games cause of the motion clarity on those side scrolling games. I don't know anything about TV repair so I'm just replacing the boards one at a time with used ones off AliExpress. Have replaced all X and Y boards to no avail. The fault is red pixels firing on dark background when they shouldn't be. Increasing the "Vscan" pot on the Y board improves the issue by about 50%, so I thought it's got to be Y board related, but no. Next I'll try replacing the T-CON, then finally the power board. If that doesn't work then it's probably the panel is end of life. I wouldn't want to replace the main logic board as that probably contains the factory colour calibration. I do have a colourimeter and some HCFR software to calibrate it but I don't know if that's the same as factory calibration.

[@G-ra-ha-m]

Maybe the remote needs to be keyed to the new main board?

Thing is you can’t get the same quality on non OLED panels and LG seems to have some of the best at the moment. I don’t think I could go back to LCD with LED backlights again.

Man, I think you gave up too fast ! Did you, at least, took your multimeter and measured output voltages on the power supply board ? Often, the values are marked, beside the connectors. I'm talking about the last one you didn't touch. This is the first place to check. Your work method looks more like a board changer, than an electronic technician. Good luck !

I am no tv technician but think it is important to remember with OLED there will be NO display without a signal .many times I've thought tv was off . Maybe try display the menu or something ,

My mother bought a LG oled c1 55" and has not had a single problem. Incredibly good picture quality. My mother uses the screen a lot. But the sound quality is the absolute worst I have ever heard from a TV! It sounds a bit like the speaker is sitting inside a bucket or plastic pipe even though it doesn't. The OLED still has problems with uneven wear or burn-in. This LG c1 dims the brightness automatically to extend its lifespan, which you can't completely turn off except in the service menu.
