Re: LCD diffusers
The mystery deepens...
My friend is coming over in a few days to pick up the TV for a real good price.
So I went to try it out and... nope. It turns on, then turns itself off after a few seconds. Try again, it works fine. Hmm, that's odd. I press a button on the remote. Off it goes. Then it switches itself back on.
All PSU voltages are okay. The main board is actually telling the PSU to turn off.
Cause: It turned out to the side button board! I unplugged this board and it is not giving any problems. I will have to see if he wants the side buttons or not.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hello,
I'm trying to repair a UE50NU7022KXXH with a cracked diffuser/lpg and now also with burned leds
There are 4/5 white spots on the bottom that are not visible since the left side is dark now so I want to change the diffuser/lpg
Looking the samsung spare parts, I see that there is a DIFFUSER PLATE and a LPG so I'm wondering what is really broken?

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
i have a 65" samsung UN65TU700DFXZA. my kid sprayed cooking oil from a spray/mist bottle onto the screen (2yr old thinking she was cleaning). oil ran down and seeped under the bezel on the bottom of the screen. It appears to have soaked/wicked into the diffuser i have a light colored splotch along the bottom of the screen that grew upwards over a day or two.
i have not disassembled yet but judging by the way it wicked up it looks like its been absorbed into the diffuser so i don't have a lot of hope of cleaning it.
i checked Samsung parts site but they don't... -
I have a Samsung 40” NU series tv with the melted cracked diffuser I’m fixing. I replaced the backlights and I’m planning on cutting a new diffuser out of a 55” diffuser that just melted but didn’t crack.
Question is do I have to keep the top edge factory for the diffusing to work properly or does it matter?
only get one shot at cutting it so wanted to make sure.... -
I replaced a diffuser because the other one was melted I accidentally scratched it. And now it shows up in the picture which I thought it would. Is anyone here have a way to get the scratch off (doubt but might as well ask) or has anyone done this and flipped the diffuser shield because I think it's scratched on the front I can't really remember but is anyone had success flipping it and then the scratch might go away?
It shows up in the light in the picture
