Hi i have been searching now for a few days trough the forums here but did not find anything to my particular problem
the monitor i have which i picked up, has 2 boards inside the SMPS is model No.: PTB-2098 and the MainBoard/controller board or what ever it is called is PTB-2038 also i must admit i am new to this but willing to give it a shot, i also searched for a Service manual but could not find any. There is no LED indicator showing up. i measured 5V on the outputs where its labeled 5V and it gives 5.18V on both, that is when i connect the negative lead to the chassis and the positive one to the labeled connections. some other things that i measured are in pictures of the board, i have checked the Capacitors, they all seem fine, i.e removed them from the board and checked them with my DMM which can check for capacity there is more information about pin measurement in the pictures. the indicator LED i have also tested it words when sending a current trough it with the DMM in Diode mode. Any help is very much appriciated
