Re: 2 x Samsungs 2493HM - Double the Trouble!

OK

I tried to put a new capactior on the "exotic board" and put everything togerther. Now nothing turns on. I think I probably didnt solder on the cap right.

You mentioned cleaning the board but I dont think I quite understood it. There seems to be some clear residue on the board. One problem I had even though I read some soldering guides:

I preheated and tinned the solder point I have a 15/30w switch solder iron which I put on 15w. I touched the component lead and the area I wanted...

Re: 2 x Samsungs 2493HM - Double the Trouble!

I tried to put a new cap on, put everything back togerther and now the LED wont even come on. Considering that this monitor also had problems with color and the menu wasnt working I am thinking of taking my losses and moving on. Thanks for all the help Im glad that at least I got one working perfectly.

I might have a look and see if I can see this model being sold as defect for cheap, then buy it and see if I can fix it with these old parts as well as buying new caps.

Re: 2 x Samsungs 2493HM - Double the Trouble!

Great help with putting me on track on swapping things around - I now have one fully working monitor. I put board A into housing B and now everything works perfectly.

With regards to the remains, I presume the cables/other parts of the housing was causing the color problem and the menu not showing up. Not sure what to do now. I will try and put a new cap on the board and connect up and see what happens.

Re: 2 x Samsungs 2493HM - Double the Trouble!

"SY 105C"
"08/10"
"C2"

I presume SY is the series identifier.

I am thinking of buying and replacing all the caps on the power board with panasonic ones, do you think this would fix the problem with the color etc. and the problem with the other monitor not turning on ? With regards to the green pcb that I kinda ruined any tips ?

Re: 2 x Samsungs 2493HM - Double the Trouble!

Monitor 1: It was working occasionally after "heating up" but then I saw the bad cap and replaced it and now the LED is constant but it doesnt turn on. This to me just suggests that either the cap I replaced it with isnt good, or I didnt attach it properly (the green pcb problem).

Re: 2 x Samsungs 2493HM - Double the Trouble!

Monitor 1: I used a Yageo 105C 16v 2200uf capactior, sorry I cant say whether thats low-esr because I don't know what that is.

Monitor 2: How would you reccommend cleaning it, and can I just solder where there is some green near it ? I thought it would have to be near/on the fine black line ?

Im new and probably screwed up, please be kind

I have 2 Samsung 2493HM monitors, I saw that both of the monitors had a bulging 10v 2200uf cap on the power board and replaced them with a Yageo 16v 2200uf cap. I read that the extra voltage is a good thing, but perhaps I should use a better panasonic cap?

Monitor 1 - Kinda works now but the color isnt right (too green) and I cant seem to use the menu (tried unlocking and resetting monitor but it doesnt work). Also it buzzes/hums a little. Could this be a cap related problem, should I try replacing other caps or the same...
