    Hanns G HG281D 28 inch display flickering on startup

    My HG281D flickers on startup and, although there are numerous posts on the subject here, I am having trouble identifying my main board revision so I can buy a cap kit for it.

    Could someone help me identify which cap kit I need to purchase to fix my monitor?

          Caps are in and all seems well.

              @shelet, thanks for the repair feedback. You should get the set of caps for the power supply also.

                Thanks budm, I'll probably get to that when I have more time and some soldering wick handy.

                  Re: Hanns G HG281D 28 inch display flickering on startup

                  For the main board i changed: C80, C83: 100UF 16V Low ESR type 105C.

                  With 470uF 25V, with some Chinese Caps... Running perfectly fine now.

                  I had vertical weak lines, flickering, blackout... black or dark content would run better/longer than white..

                  The two 1000uF 25V on the powerboard and the regulator were hot when disassembling the HG281D.. Did nothing with that ... Would that be a problem later?

                  Thanks a lot for this forum .. Saved me a 28" secondary monitor :-)
