If the menu is appearing then it should be able to adjust the Monitor, provided you have replaced the micro switches. Check for continuity by pressing the buttons. I don't think that there is any prolem with other components.

It has nothing to do with any software. This seems to be an hardware issue. Most probably it is the heating up problem. When you switch it off and connect it back after few hours, it cools down and works again. So, it is recommended to seek professional help for internal repairs of the monitor.

Hope it helps! Good Luck!

Pincushion and Horital Size Problems


This is a hardware based issue, and sadly cannot be fixed without sending it to a service center. If you really want to, you can send this monitor to a service center, but it will be around 100 bucks to fix. I would say just replace it with a smaller LCD panel. They can be bought for around the same price, and they'll save power too.

Issue with my 17" Viewsonic VA1716w LCD monitor


If all the buttons on the front don't work I would beleive it was a cable that is not connected correctly. I've seen things like this happen on otherwise perfectly good equipment. It's probably an easy fix however, monitors have enough power to KILL YOU (dead not a little bit very dead) if your not sure what your doing find someone who is most things I encourage you to open up and play with but not monitors. (did I mention you could die)

Problem with monitor


Hi,

Your post/description indicates a "pincushion" problem; the width problem is as you have stated.

There are two (2) possible reason for these problems:
1. component failure in the horizontal section of the monitor. These components could either be a diode, a capacitor or a resistor. In some cases there are trimpots in the PCB that can be adjusted to correct these problems;
2. component/connection failure in the controller section.

Of the two, I tend to suspect #1 as highly likely the case. Repairs such as this would require that you be familiar and comfortable working with electronic components and circuitry, the use of a DVM and a soldering iron. Should this be not to your liking, your next best bet would be to seek the services of a qualified professional.

Hope this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Wide Screen Problem (Pincushion)


Some countries get themselves 'burned' to a spot because of lack of use. a slight twich one way or another will reset it . The control that you are referring to is it a direct acting one - that is does the work or is it of the switch variety- that is you activate the control but then have to move larger wheel to do the work?
