  • Replacing resistor and cap (no schematic)

    I've got a similar problem to this guy [URL="https://www.badcaps.net/forum/showthread.php?t=7523"]here[/URL]. I've pulled the board out of another DCLCD monitor.

    Specs: SOTAC Model HOAU462001 Rev 1.0

    As seen in these two photos [URL="http://i.imgur.com/cpGVB.jpg"]here[/URL] and [URL="http://i.imgur.com/cR20M.jpg"]here[/URL], if you look just right above the toroidal common mode choke coil, you will see two empty spaces. One of which is for a ceramic capacitor and the other for a 1/2W or greater resistor. These are R88 and C65.

    well, I figured out my problem above. One of the transistors I put in was faulty. You can easily test transistors with the diode voltage on a typical VOM and using google for instructions. This thread alone has about 53,000 views, so this is a typical problem for people..so I decided to take awful pictures of an awful setup.

    Here is my sweeeet setup supported by a torque screwdriver nonetheless:


    Always make sure that grounding pin is actually doing something just in case.

    I changed out the 4 transistors and now when I power up I get my desktop for about 2secs and then blackness, but the power light stays green. I know this is common for some people on this board, but what could be the problem? Maybe this happens when one of the transistors was not soldered on right?

    I noticed the fuse was all white so I did a continuity test and all checks out, but is it supposed to appear white? Thanks
