Re: DELL U2311H 2 second issue but works after some try´s

so... soldering done, changed all the caps from the power supply except the big one. all solderings are good, contact wise.

but... no change

maybe it needs less on and off switch cycles to turn the monitor finally on, but that´s not a big change didn´t try that so often.

maybe is the backlight flickering (bright, a little bit darker, bright and so on, for about 10secs) after the monitor finally stay on the issue?

or should i change the caps on the...

i also got a heatable desoldering pump which should make things pretty easy i didn´t think that it would be hard without but im kinda lazy guy ^^ and the pump wasn´t that pricy.

First, thanks for the answers!

Nice to know that DELL uses those cheap caps

I will order all caps except the big one and re-solder all of them

Panasonic caps should be fine?

i´ll keep you guys informed if it worked. this weekend i should get this done.

So finally i made some pictures

please klick [URL="http://imgur.com/a/yAVmJ"]*here*[/URL]

hope pictures say more than 1000 words.

i didn´t saw any blown cap´s from my pov all looks fine. but i think also a cap could be altered and not fully working.

i wrote down the specs of every cap i found so maybe i replace every cap that´s on there. do i need DC caps or normal ones?

shouldn´t be that hard to solder?

do ya think...

DELL U2311H 2 second issue but works after some try´s

First of all please excuse my bad grammar

One of my DELL U2311H got the following issue:

But the miracle is that when i try switching on and off a few times, the monitor switches on and the display flickers for a short time (10 seconds or so) and then the monitor works fine till i switch it off.

maybe thats an...
