hanns-g hh251: evenly dim dispaly, high pitch cap noise, no brightness control
I have a $15 thrift store prize I want to ressurect. Its a Hanns G hh251hpb that is dim evenly over the surface of the monitor and the brightness does nothing. I took it apart and inspected the board and found no visually bad caps. The inverter and powersupply are one piece. it has a high pitch noise when on, as well as a less intense noise when off and plugged in. I also noticed that the noise changes when it is on and i wiggle the wire for the top ccfl, and if i get too crazy, it goes off. i will post pictures this evening of the board. Any ideas?
