Samsung Syncmaster monitor 24" & 26" caps same?

[Delicieuxz]

Hi, I have a Samsung Suncmaster 2693hm monitor that is expressing black flickering for a minute on cold turn-on, and so I'm preparing the replace the caps in it and expecting that to resolve the issue.

Looking around online, I've found that there is much information regarding the replacing of caps for the 2493hm Syncmaster monitor, which is the same model but just 24" instead of 26".

For the 24" model, I've found a full listing of its caps, as well as a prepared capacitor replacement kit for the 24". The links for those things are these:

I haven't found the same information regarding the 26" model, but I wonder if its power board should require all the same caps as the 24" one, if it's the case that only the screen is a different size.

Is it likely that the two models will have the same power board components, and use the same cap values?

You should always check the component values yourself before ordering anything.
There can be component variations even in two identical model monitors, so it is very likely that you will have different parts in your monitor.
Also it may necessarely not be bad capacitors, could be something else. That is another reason why you should open up the monitor and inspect it before doing anything.

For some reason ccl-la blocks Finland so I can't access the site, but usually you can also save quite a bit by ordering the parts separately, ie. from digikey, rather than buying a kit.

Ok, I've now opened up the monitor.

I don't see visual damage on the power board or inverter board, and I haven't yet looked at the screen's components, which aren't immediately accessible.

Is it possible that a bad component will not show it on the outside, and should components other than capacitors initially be as suspect?

I would advise you to start a new thread in the troubleshooting computer display section AND put the model number and the problem in the title - Flickers on start up?
If you have not seen them, there are a few threads on this monitor if you search for 2693HM using "search" at the top of the page.
Post good clear pictures of your boards front and back and one of the whole set with the back off so we can see how they connect.will enable us to help you better.
It could be a cap problem but other problems could cause this. A first "test" would be to warm the capacitors with a hairdrier before you switch on and see if it helps.
If it does try warming different areas to find warming which board helps most.

Thanks for those suggestions. I've now posted the issue in the forum you advised.
