Re: Display problems

There is a hotfix you can download from the WYSE Website but you have to setup a FTP server to get it installed. An easier way that seemed to work for us so far is go into Control Panel -> System -> Memory Tab. Adjust the memory slider so about 1/4 of the memory is set aside for Storage Memory (The systems I changed had between 90-100% set aside for Program Memory leaving 0-10% for Storage Memory.

Wyse 1200LE - error - out of frequency

This is caused by the terminals default display resolution (or the resolution that it was set to in its previous environment). The easiest way to get a display, would be to use a different monitor with a higher range of supported resolutions.

Fingers crossed the previous wnos.ini file would allow a G-key reset. If so, just hold down the G key when the terminal is booting, and it will reset to factory defaults. This might allow your monitor to work. (I think the default resolution is 800x600)

The problem you have is that the terminal might be locked down via the .ini file. So changing the configuration might be difficult. You could use a program like Wireshark to perform a network trace, this would tell you where the terminal is looking for it its wnos.ini file.

Then you will be able to setup a new wnos.ini on an FTP server set to the IP address(and path) the terminal is looking for, and this will allow you to set your own configuration.

Monitor flickers with changing colors making it almost impossible to see anything, it started & stopped for a while then after maybe three weeks after it started again ! I tried disconnecting & changing...

I suggest upgrading the OS on these problem terminals to the latest on the wyse website. It might be an incompatibility with the monitor and terminal (might have been fixed in later builds), in which case you will need to log it with Wyse directly, as they will need to test this.

Chances are though you either have a faulty monitor cable, a faulty unit, or faulty monitor. Perhaps even a combination of more than one of these above problems. Try to rule out each bit of hardware before blaming anything in particular.

Try a few different monitor resolutions, colour depth and refresh rates too. Cant hurt :)

How can i reset S30 wyse box

Try a G-key reset.

Failing that use WSI and an S30 image from the wyse Website.

WDM also has the option to to re-image the client.

You may also be able to get into the control panel of the terminal, and download an FTP image and set the terminal to upgrade from the image when uploaded to your ftp site. From the control panel, you can initate the upgrade manually

Try resetting with Control + g rather than just g

Turn on the Winterm and immediately hold control + g (at the same time)

The display should flicker for a bit then release the control + g

This will reset the device to factory defaults, (you'll lose your connection settings, network settings, etc) -- but you'll be able to use it again. :)

The display settings are not valid with the monitor. Either you are using a new monitor or you have changed the settings. If you are using a new monitor, swap with the old monitor and configure the appropriate refresh rate for the new monitor.

If you have changed the settings you may need to either reset all default settings, or setup a parallel unit and use the same key strokes to change the display settings on the problem unit.

No display in monitor

This may be the problem with the WYSE driver. Ensure that correct driver is intalled and colour profile is compitable. Syncmaster is auto detected by window based OS.the message "Sync out of range" comes due to improper out put video signal.
