    Samsung 244T monitor won't turn on

    Hello,

    I have a samsung 244T monitor, which was not turned on recently. What I did is replace some bulked capactors on power board, no change. It still not powering up, no light, etc. So, I purchased a used power board from ebay and replace it. Still, no change. Can anyone give some advise if the drive board on my monitor goes wrong? Or is there any easy way to identify if the drive board is working or not? This is a good monitor, so I want to spend some time to check if it can be fixed or not.

    Many thanks!

      Thanks for your reply. I took some pictures. The first 4 are my old power board and the new one purchased from ebay. The last one is the drive board. Any ideas?

          Thanks for your reply! By the way, are you referring to the area with marker number 417?

              I loaded more pictures for this drive board and want to make sure this is the one you refered. Curious to ask, how did you find the IC component from top right area was burned, it seemed fine to me. Can you give some comments in more details? Thanks a lot!

                Upgrading a Samsung ue55nu7096u with logic board from an ue55ru7105k -- good idea?
                by ohren
                I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.

                I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.

                The models launched in 2018 and 2019 respectively....

                HannStar Hanns-G HC194d LCD monitor repair
                by momaka
                Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                Samsung Power Supply Board BN44-00874F
                by Nicktronic
                Hey everyone,

                This power supply board is hard to find but there are repair kits available. This board had a blown fuse, FP801S, blown PFC MOSFET, QP802CS and ceramic cap, CP809. I replaced them with parts I already had and tested the rest of the parts that would've come in the repair kit and they were fine. I powered the board up on the bench expecting, in typical Samsung power supply board fashion, to see all my output voltages but, nothing. 0 volts on CNL801, CNM801 and CNT801. The only thing I have is 170vdc on the filter caps. No standby voltage either.

                Anybody...
