No amount of fiddling with the ribbon cable seems to improve it, I think I might have to admit defeat on this occasion. Thanks everyone for your input -
I am really hoping this is a bit of dust in the connector! [ATTACH=JSON]{"data-align":"none","data-size":"large","data-attachmentid":3261313}[/ATTACH]...

I don't think I will be able to resolve the issue in the bottom left fully as manually applying pressure hasn't changed much - BUT I'm really happy with the result. I'm going to put the panel back on once the capacitors have had 20 minutes to discharge

Thanks again for the fantastic tips. Will give it a go tomorrow and see where we get to. I did this in a rush this afternoon, I think as you say the corners are either not quite snapped in correctly or the weight of the tv sat on it is distorting it. To be continued!Leave a comment:

I'm going to need to take it back apart to give the diffuser a clean but we have progress!

Looking again the patch has moved after it's been stood upright for a few days - lets hope it's just water....!
Final question before re-asssembly - does it matter which way round the perspex sheets are in terms which side of the sheet faces the front? and if so how do I tell which orientation is correct? I have the sheets in the correct order I thinkLeave a comment:

Right I've picked up a UE49NU7172U for £10 to use for parts for this. The screen was smashed so initially I have disassembled the TV to check it's backlight is all working correctly and....
Has the broken panel somehow leaked into the diffuser? Or does it just need carefully wiping clean? I have the bulbs here to do the backlight so that should be simple enough
This is turning into more hassle than it's worth!

Thanks both. I've found a smashed UE49MU6220K a bit further away, but the seller wants silly money for it. Might have to bide my time until something smashed comes up!Leave a comment:

Answered my own question - AU seems to not use edge lighting [url]https://www.aliexpress.com/item/1005005628342872[/url]https://Answered my own question - A...28342872[/url]Leave a comment:

The ordered diffuser turned up and it's the wrong one so I'm looking at other options. There is a smashed UE65AU7100K locally - is this edge lit or something else does anyone know? Cheers, RufusLeave a comment:

Thanks for coming back both. Sale of the MU unit fell through so I've gone ahead and ordered a new diffuser and backlight - total cost £32 delivered. Lets hope that sorts it
[USER="314794"]Storyteller12[/USER] I can see why you are so anti repair on these units - awful design - but the set is going to be for personal use and I'll just set the backlight on a low settingStoryteller12Leave a comment:

You make an excellent point - I'll order the cheap one.
In case anyone was in doubt....

There are two different diffusers listed as available for this model - BN61-15664A & BN61-15658A - if I disassemble mine is this part number etched into the diffuser somewhere? Or is there another resource for finding which would be the correct part?
Thanks in advanceLeave a comment:

Thank you [USER="477674"]EazyBone[/USER]. If you're also replacing the backlight on these models is it worthwhile paying a premium for some sort of nicer part? Or will a cheap chinese one do the trick?EazyBoneThank you [USER="477674"]EazyBone[/USER].

Cheers [USER="477674"]EazyBone[/USER] but it looks like the MU range I was looking to transplant have a different style of backlight - full array, i.e. from the top & bottom rather than just the bottom. I am hoping to hear from [USER="314794"]Storyteller12[/USER] as it sounds like has successfully transplanted a MU backlight onto an NU screen, but this could well be outside my skillset if it requires significant work
Otherwise it looks like a new diffuser is available for roughly £20 delivered as option 2 [url]https://www.sos-parts.com/diffuser-tv-samsung...Leave a comment:

Some useful information narrowed down, but the pictures I'm looking at of the stripped MU look like an edgelight.... Further research required. Thank you [USER="314794"]Storyteller12[/USER]Storyteller12...Leave a comment:

Can I fit a UE49MU6470 Diffuser into a UE49NU7100K?
Evening all,
Long time no post!
I have a UE49NU7100K here with the classic melted diffuser and damaged backlight from getting too hot. Locally there is a UE49MU6470 available which I could pick up to replace the melted diffuser. Would this work or am I missing something? They look like the same style of backlight.
If this sounds good, where is the best place to buy a new backlight? Will I regret buying from Aliexpress?
Thanks in advance for any help -
Re: Samsung UE43J5500AK picture issue
Ah ok so with the side tabs missing you cut individual lines of pixels instead?
I'll be honest I think this repair may have gone beyond my level of expertise, so I might stick the whole TV on eBay.
Davi if you find out any more about these style of issues please post up on here, even if it's in a year's time. I'm sure there are other forum members who could benefit from any pointers.

Please don't take offence, I have got a feeling English isn't Davi's first language so applaud him for making the effort to post. I feel sure he didn't mean to offend you at all

Re: Samsung UE43J5500AK picture issue
If the TV can not be saved by conventional methods I'm perfectly happy to have a go with "experimental hack jobs" to expand the knowledge of the forum if nothing else. I don't think any forum member would intentionally supply dangerous fix instructions, an element of common sense must be used mind you.
If it helps I can tell you all the defects shown in the right hand side were mirrored to the left, there was no improvement in picture. If you'd like another picture I can take another?
