    Help needed: How to Crack Open Samsung 941BW?

    I've got the base off, as well as the inverted T shaped back cover. There are three Phillips head screws holding the base holder to the monitor, which I haven't removed yet. I see four rubber plugs that the protrusions on the T shaped back cover snap into.
    How can I get the monitor apart to check the MB? I suspect I may have some bad capacitors. I'm guessing that there may be screws under the rubber plugs, but I want to have that verified (I don't want to screw them up.....no pun intended). If that isn't the way to go, I'd like some helpful advice on how to get the monitor halves separated.

    I don't think you have to unscrew the base holder.

    I don't have experience with that particular monitor, but the following video may apply to yours as well:

    Instead of knives, some use credit cards or something slightly more solid than a credit card. Some use those spatulas used in kitchen, or whatever they're called.

      Use a putty knife and slowly disengage the tabs.

        Thanks for replying so swiftly....to both of you....
        The You Tube video was helpful, and I will use a putty knife to split the halves. I have an unused one with a very thin blade.
        Once I open the monitor, find out what has failed (most likely capacitors), and, if that's the problem, I'll replace them and get back with the results. Thanks again Mariushm and nickt1862.

              Removed the PS. Sure enough...it's full of CapXon capacitors. Some are bulged. Looks like Samsung joined many others by installing some of the crappiest capacitors. I'll replace them with quality and report back.

                Yeah, of the various Samsung LCD monitors I opened up they're full of CapXon, Sam Young and "xyz" branded chinese crap caps.

                Best to replace ALL of the caps.

                  Samyoung and Samwha are actually Korean. They are still crap though.

                    I don't even love SAMXON, tells you how picky I am.

                      Thanks to all of you for your generous help                      . Without it, I couldn't even have figured out how to crack the case. I've replaced the caps with Panasonic...at least I think so. Well, anyway the monitor works like new.
                      The reason I write "I think so" is because some of the caps don't have the Matsushita "M" logo on them. The "T" vent is impressed on the top. There is a silver stripe with the Panasonic type minus signs on it. But, there is no name or logo on any of them. Other than the specifications, 1N30TK is printed on the side of a 1000μF, 25V,105ºC FR capacitor. So, I wondered if some are counterfeit. Does anyone have a clue as to whether they are likely to be genuine Panasonic caps?

                        If you got the Panasonic FM/FR from digikey as budm recommended, then there is no need to worry. If you went on ebay, then you probably got fakes.

                          They're Panasonic, Matsushita is the "mother company" and T is their top... FR series is black with silver line so everything sounds good.

                            Thanks for your helpful response, mariushm.
                            A few days ago, I e-mailed Vince Pastor, Sr. Product Specialist - Aluminum Electrolytic Capacitors - Panasonic. I got a response from him yesterday. He verified what you said, and also said that some of the Panasonic caps don't have the "M". So, it looks like I'm good to go with genuine Panasonic caps.

                              Nope! Not e-bay. Panasonic says that's the normal configuration for those caps.
