Hi All just picked this up and it appears to have some kind of stain on the back of the screen that the backlights pickup as if something has been spilt on it,apart from this it all good.So my problem is how much of a job is it going to be to get to clean this up and any tip on how not to muck it up? I tried to take photos but the marks wont show up. thanks

Re: Wharfedale LCD47F1080p marks on inside screen
It should be easy to take apart, TV's usually are compared to monitors. Try messing with some camera settings to try and pick it up in a picture, try with flash off, macro mode, etc -
Re: Wharfedale LCD47F1080p marks on inside screen
I did try all the setting on my camera but they all failed to pick it up, its not bad just annoying starts at the top of the screen to about midway down in three places, the set is covered in dust and this happened after the guy moved and the set was left in storage. I think with all the dust that maybe it was raining when he moved, I will take photos when i pull it apart more for me so it all goes back the way it should, Any help on striping the panel would be gratefully receivedComment

You will need a room as dust free as possible -even then you will get some dust in. Read up on it before you do it - if you are keeping the set and can put up with it it may be better than dust.
You may be able to find videos on youtubePlease upload pictures using attachment function when ask for help on the repair

Re: Wharfedale LCD47F1080p marks on inside screen
Thanks selldoor for pointing me over to youtube it seems this is a common fault and it is the polarizing film that wrinkles in the back of the screen. someone on there said to try an ice pack over the screen to shrink it back, oh well ill try anything once if not i will pull it apart.Comment

I have found loosening the screws to reduce the effect and also dropping the backlight a little.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hi Tom the screws you refer to are you talking about the metal panel frame ? And backlight setting would be in the factory setup menu i guess would you know the access code for this set. thanksComment

Re: Wharfedale LCD47F1080p marks on inside screen
Some tvs backlights cant be lowered.
If its been in storage for a while it might have been a little damp, and the damp could of carried some of the dust in between the film layers.
Not sure how possible that is though.
Take apart and clean it, make sure its perfect before putting back together, even a little strand of hair will be visible at certain angles.Do NOT touch heatsinks when testing for voltages as they may be LIVE!Comment

Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
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... -
I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.
The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While... -
i have an ipad pro 9.7" (1st gen) A1674 where i replaced the screen, but never attached the screen to the frame/chassis (glued down) due to the ipad being previously dropped so the new screen would never fit in the frame properly. so i need flex/bend the chassis to eventually fix the new screen in properly. so i temporarily just applied blue tape around the edges of the screen to keep it in place. when watching videos with the ipad the screen started flicker, so i though maybe the new quasi cheap amz screen i purchased was going out. so i disconnected then reconnected with power still on,... -
Hello guys. I'm a complete noob in electronics. I'd like to repair my child Lunii's (a "story box"), basically an audio player that allows the childs to choose between several options the places, characters, objects of the story, and then play a story according to the choice of the child. There is a screen that display the selected option before each choice. The Lunii fell and the screen is now broken.
I'd like to repair it (probably just have to change the part, because the lunii still works perfectly fine) but I can't manage to identify the part/order it online. Do you have any...02-17-2025, 01:16 AM
