Hi guys, sorry for the lack of info on this, I have a Samsung 37" think its a 4 series, the image and sound are but the whole screen is really dark, turning contrast and brigtness up helps a little, can someone point me in the right direction, cheers, should i be tempted to buy a new inverter board ?

Re: samsung 37" dark screen
Firstly a model number would help plus Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem -

Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same... -
Hello Everyone,
This is my first post so I will try to be as precise as possible without making this post too long winded. Unfortunately I don't have pictures of the original problem but I included images of the TV internals.
I have a Sharp 70LE660U. The problem started a few months ago with the bottom row looking out of sync and was dark on the left side and then fading to transparent on the right side. Shortly after, a dark cloud appeared in the center of the screen. The dark cloud started small and shaded but the image was visible. It also affected the menu area.... -
Hi it looks like everything works don't know where to test except the 390v in the 2 capacitor in the hot side of the power supply and the weird 180v in the diodes in the cold side that should be discharged it is writin on the circuit no more you can read what is written on the circuit quite srrange color mixiing yellow and white
anyhow i couldn't t read anything else
the backlight is on strong and the screen does not get dark or very dark but no pictures
the mainborad feels a bit hott on the black part i test it to 52 degree's against 34 to 40 on the rest of it

Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
Ive eventually managed to get it on and working but it's very temperamental...
The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...05-26-2024, 12:05 AM -
Set from 2019.....sad this is all they last anymore. Ok, obviously a backlight problem. From what I understand there are 3 strips in these, mounted vertically....one seems to be bad. The image is present behind the darkness, not a LVDS or TCON issue.
This TV is a beast. I can't even manhandle it by myself, let alone try and lift the screen out to restrip it.....but I haven't even gotten this far yet....I can't seem to find strips for it.
I found a set for the UN75RU7100FXZA but not the 7200.
