Hi all, Need a service and repair manual for Dell E198WFP. Seems impossible to find. Any help out there?
I do have a side comment about monitor service manuals and that is the information contained. Most monitors contain a Benq power/converter board of a type or flavor. It seems impossible to find a schematic that agrees with what the wiring looks like.
An example is the HP 1740 monitor I recently download from this forum. The power supply section is pretty close but has quite a few differences. An example is the 2A AC input fuse on the board. The schematic indicates a 3.15A fuse. On some HP1740 schematics the fuse is located on the AC hot side of the line. On the board I'm repairing it's on the low side. All boards use both a chassis ground and a floating ground. IF one is not careful it's possible to zap yourself.
Not only that the converter board is like the conventional Benq board. Those of you who repair computer equipment will know what I'm talking about. The 2c5707/06 switching devices and the 2 mosfet controllers. The PWM's are usually different.
A call to Dell or HP or Benq is a waste of time.
