Can I fit a UE49MU6470 Diffuser into a UE49NU7100K?

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 think

The best thing to do is to put them exactly as they were at the time of removal
Because if you turn them 360 degrees it can have a big effect on light reflectivity that it can get brighter on the upper part

The correct order matters, I don't think orientation will matter. The diffuser orientation matters.

Disconnect the main board and plug in the power cord and the LEDs should turn on, then you can flip them up and down while it's plugged in and see for yourself. I would do this anyways after installation of the diffuser because there is always small points that might not be clipped etc and you'll catch any imperfections before you reassemble the whole TV

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

You have bright spots in bottom corners, make sure the snap connectors are down enough. That's going to show up on the picture. Those other spots, put the sheets over top lay it flat and turn it on, it hides some of what you see so brightly. Then you'll have a better estimation of what you need to cleanup. Not all of that will show through

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!

Yes! Everything should look as close as possible to this area here or it's going to show up once you put the tv back together. Like I said put those other 2 sheets on and lay it flat, and put lights on and some of the defects will go away. But definitely not those bright spots

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

[fuus]

I am really hoping this is a bit of dust in the connector!

[EazyBone]

Oh boy 😮 😮

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

Yea, I've had this happen once before, but to be fair the backlight was out so maybe it was already there before changing it. Sorry to see
