Question about Nokia 447Za Monitor
I got this monitor from a friend and did not get any manuels or other disk to help me learn how to get the speakers and mic to work. Can you give me some sort of information on how to setup or fix my problem...Thanks Terry

Hi shah. It is most likely that the speaker's transformer is burnt. If its under warranty then the showroom guys should fix it for you as its covered under warranty. Otherwise you will need to take it apart remove the old transformer and install a new one. I strongly advise "if you are not familiar with electricals then better take the assistance of a qualified engineer".

The adjustments you need to make are for the screen geometry. I haven't been able to locate a manual, so I can't tell you exactly how to access them. Usually there is a menu button that brings up the adjustments, and a couple more (usually marked + and -) to go through the choices and change the settings. A fourth button enters your choice. On some monitors there may be an adjustment knob/button combination. Press the knob to enter, and turn the knob left or right to adjust and choose.
Having said all that, what you want is called the pincushion setting. When set properly the image will be square. Improper settings cause the edges to bow in or out. Depending on how many adjustments your grandkid messed up, you may have to go through some other settings as well. Most monitors have adjustments for:
- vertical and horizontal position and size
- pincushion (adjust for the straightest top and bottom edges)
- trapezoid (also called keystone) which adjusts the top and bottom widths in opposite directions (adjust for the same length)
- parallelogram which adjusts the top and bottom positions in opposite directions (adjust so the sides are straight up and down)
There may a few other choices, but the previous ones have the most effect. There may be a choice in the menu to reset everything to midrange. If so, take it and then use the adjustments to fine-tune if necessary.

The electrical contact surfaces under the rubber buttons lose contact over time. I don't know if it's corrosion or some kind of build up. I fixed mine by disassembling the monitor, removing the button panel and cleaning the contacts with a pencil eraser. It works great now. The monitor is a real bear to take apart though. There are four hidden spring tabs on the sides of the bezel that are impossible to see. I groped with a very thin screwdriver blade and finally got them to release, but not without chipping some of the plastic.
