hey everyone, is there any place to get a cap kit for the dell 2408wfpb? -
Re: LG UBK90 4K Blu-Ray no power
new caps arrived, took me about 10 or so minutes to replace them all, i did remove a pad by accident as you can see the green wire, but i managed to fix it and it tested fine and i added some hot glue to the cap on that side to keep it from moving
thanks for all of the help and advice and heres hoping this thing lasts a lot longer...Leave a comment:

Re: LG UBK90 4K Blu-Ray no power
i thought it was weird as well and i double checked and scrapped away the glue that was on it and it says 47uf 460v, i am also attaching a screenshot of what i have added to my digikey cart to replace the caps with
i did check for bad and cracked solder joints and they all look good, though when i replace the caps i will give them a once over with my iron just to be safe...Leave a comment:

Re: LG UBK90 4K Blu-Ray no power
i plan to just replace all of them but i just cant find a replacement for the big one in 460v max i can find is 450v and even then the best i can do is nichicon and the others are rubycon...Leave a comment:

Re: LG UBK90 4K Blu-Ray no power
there is no edit button and i hate to do a reply, but i just did the air dryer method and it works! so you were right, its a cap, but the question is which one, i guess best bet would be to replace all 5 of them just incase to keep this from happening again in the future
EDIT i have started pricing out the replacement caps and the only one i am having an issue finding is a 47uf 460v capLast edited by luke9511; 04-04-2023, 09:25 PM.Leave a comment:

Re: LG UBK90 4K Blu-Ray no power
i have tested the diode and it tests fine however test the STF8N80K5 mosfet is giving me some odd results, but it would seem from the different data sheets and videos and other websites that the mosfet is dead, is there one i can replace it with that is a little easier to find? i know i could use digikey or mouser but those will charge a lot on shipping when i only need one
EDIT: stupid me forgot the part number it is 8N80K5Leave a comment:

LG UBK90 4K Blu-Ray no power
hey everyone, i picked up a LG UBK90 4K Blu-Ray player for free off of facebook market place and the issue is that it does not power on, i have verified that there is power at the plug on the power supply and that the fuse is good
however it will not turn on, i started probing around trying to find the issue but i only have a basic multimeter right now and i am looking for some insight
Can anyone here help me confirm if this diode I am looking at is bad, I don't have my good meter but according to a fluke article, it should be between 1000 ohms and 10 miliohms, if... -
Dell 2408WFP no picture
Hey, everyone, I got this monitor for free and It was working fine and then I had to unplug it from the power and when I plugged it back in I was greeted with a messy white screen and not able to switch inputs or see the OSD menu,
now I dont get a picture at all and if I hit the side of the monitor the picture would blink like it is trying to correct itself but it does not do anything
I took it apart and checked all of the caps and none looked bulged or anything but now when I turn it on I get the green led on the power button and a black screen but I can tell the... -

p2715q
hey everyone, i have a p2715q with what appears to be a bad backlight i think, as i thought it was dead until i plugged it in and hit the power button and happened to be at the right angle to see the dell logo flash on the screen even know it was very dark
does anyone know if it is the backlight it self or maybe something else? i havent pulled it apart yet as it may still be under warranty but i figured i would ask here just incase. -
