im not so sure that the Samsung cells are right for a few amp constant load looking at the review on that site
<whitequark>
a few amp is generally not a problem for cells
<whitequark>
once you're looking at >5A or 10A you start having problems

eintopf: on the topic of fixing monitors by swapping capacitors: the important parameters are capacitance, voltage, and mechanical compatibility
<wpwrak>
if you can't get the right capacitance or voltage, you can always use some larger value. you may be able to get away with slightly smaller values than the original, too, but you'd be taking chances.
<wpwrak>
size increases with capacitance and voltage, so this limits how far you can exceed the original values.
<eintopf>
I think I need these, but I better lookup again which capacitance they use
<eintopf>
and I don't do experimenting stuff :D
<eintopf>
just replace the same values
<wpwrak>
pcb looks familiar :)
<eintopf>
pcb?
<wpwrak>
the board
<wpwrak>
the values are written on the caps. very easy to find those values :)
<eintopf>
yes, there is no unknown stuff on the board
<eintopf>
it's very open hardware friendly if you have the chance to open it
<eintopf>
-> Problem: Blinking power led, the display do not start properly. The main reason is the capacitors of internal power supply.
<eintopf>
exact my problem
<wpwrak>
now, you have to be careful about size. first, of course, you want to make sure the contacts have the same arrangement. those caps usually have them on one side, but there are also caps that have one on either side. you want to make sure you pick the right one.
<wpwrak>
if the original size isn't available, then you may be able to use something bigger, but you have to check the available space first
<wpwrak>
i'd also check for burnt components. e.g., on my two problem monitors, i have various spots and components that look overheated. so i'm not sure just fixing caps will solve the problems.
<wpwrak>
also, you don't need to replace all the caps, just the ones that look defective. you can tell by looking at their top. if it bulges to the outside or has even ruptured, the cap needs replacing
<wpwrak>
if the top is nice and flat it's probably okay
<eintopf>
yes ok.

and the sizes, I solder them out and take them to the electronic market
<eintopf>
and say the people "I need exact the same but not from china pls"
<eintopf>
okay, I mean with china, not the cheapest parts
<eintopf>
maybe I should open the case at first and look into
<wpwrak>
eintopf: yageo is also a reputable company. so there's a chance they will last a little longer
<eintopf>
ok
<wpwrak>
eintopf: yes, open the case, take pictures, check if there's anything else that looks bad, write down all the values
<eintopf>
they have all what I need from yageo
<wpwrak>
eintopf: in any case, you want to see which parts actually need replacing. you don't have to replace just everything. some caps will be perfectly fine.
<wpwrak>
or you can just charge the cap to a known voltage, add a resistor to the terminals, measure the time it takes to discharge to a certain voltage, then do the math :)
