The Problem

Is your monitor too bright (or too dark) and cannot be properly adjusted by the front panel control?  The Dell P1100 and P1110 have a chassis made by Sony.  Many of these monitors develop a screen brightness failure, the monitor becomes too bright to be used.  Scan lines may be visible (some faint white lines at a slight angle).  No amount of adjustment by the front panel brightness control will lower the screen brightness enough.  The problem in these monitors has been that the G2 voltage is too high.  If the G2 voltage can be set properly, the monitor will function again as it should. * Click here for a more detailed description of symptoms

How It Works

An IC outputs a PWM (pulse width modulation) signal to control the G2 voltage.  PWM is used as a digital regulator.  The problem of how to set the output of the PWM back to where it should be arises, as there is no manual adjustment.  The adjustments in this monitor are stored as numerical data in an eeprom (electrically erasable programmable read only memory).  A processor reads the values and sends the data to the appropriate place to control the various functions.  This includes convergence, tilt, keystone, G2 and more.

The Solution

The way these values can be changed is with an interface unit and software designed to communicate with the monitor through the serial port of a PC (IBM compatible) and the port connector on the monitor.  A connection is made between the PC and an interface unit.  A cable from the interface unit connects to the monitor.

The Procedure

You may order the interface unit.  Once you have the unit and the software, you simply connect the interface, then run the software, extracting and saving the current data from the monitor.  You send this file through email.  The data is repaired and the data file is sent back to you.  You load this data back into the monitor.  That's it! Your monitor looks wonderful again!
