I repaired my friend's monitor by replacing and soldering new components on the power board circuit and it's finally powering on. However, the screen is dark or almost black but you can see the desktop, login screen etc. If you encountered this problem, please let me know how to fix it.

This is what it looks like. Halp. It was just three components but I used some with a higher voltage since people said it's fine as long as the capacity is the same.

Sauce

btw you burned your friend-s monitor.
>>
>>62048059
Looks like it's from the monogatari series, not sure though.
>>
>>62048110
You did the exact opposite you were supposed to do. Always same voltage and same or higher capacity
>>
>>62048051
Have you tried turning it off and on again?
>>
>>62048341
Proof? Everyone says its same capacity but higher voltage.

If it was capacitors you are fine.
If it was resistors you are fine.
Try to match the values next time just to be sure.
It looks like you either cooked or disconnected the backlight during your repairs.

Your back light fucked.

There is an anime source website, please use it.

Also Google finds it 99% of the time.

I guess I need to catch up.
>>

>>62048409
How? I only unscrewed the power circuit board. The display circuit board is still there. Its a pretty old monitor, about 5 years old but still.
>>
>>62048051
You plugged in the inverter cables incorrectly when assembling the screen to the board.

I've repaired capacitors myself in the past, this is a common mistake.
>>
>>62048448
You'll have to take it apart again. You might have simply disconnected the power to the backlight. I've done shit like that before.
>>
>>62048341
Actually same capacity is the correct one. Same voltage is generally recommended also but you can safely go higher if you don't have the correct voltage on hand.

Did you test the voltage output through a voltmeter? And tell me exactly what components were replaced, was it the rectifier?

kizumonogatari rietsu hen (third part).
>>
>>62048495
Yeah that was the problem actually. Wew.
>>
>>62048051
Sounds like no backlight issue.

Check the coil.
>>
>>62048051
Backlight doesn't work, obviously. Pretty much impossible to say why with no information, but I guess I'd start debugging by making sure it's getting power. If the backlight was working before your fix but isn't now, make sure you plugged everything in correctly and make sure the cables are making proper contact. If it's not that I guess I'd start looking at the backlight power circuit.

If this is an older monitor with a CCFL backlight you should be VERY careful though, those operate at high voltage. Actually since you don't seem to know much about electronics, you probably shouldn't try to poke around inside with the power on.

There's a lot of catching up. You'll need to find a list online for all the shows/seasons, and then decide if you want to watch chronologically, or as released.

>>62048784
Good job on fixing the issue.

I want to mating press that tiddy kitty for the purpose of procreation, while holding hands.

Feels really bad. If only there were compilations of the fights and lewd stuff

Around minute 38:00 for those interested in that scene.
