| Hello people,
this monitor that I have has gone dark. Even at the brightest setting its
still kinda dark. Its been sitting in the corner for about a year. I want to
open it, and try to brighten it from the inside. I have worked with Wyse 60
monitor before. Does anyone know where I can get the inside blueprints for
this monitor?

voltage path and short it out. This also works for TV's where the CRT is
getting tired.

| If you don't understand I don't think you should be opening it at all, they
can be dangerous even long after they're switched off. Take it to a good TV
engineer.

It isn't the brightness control, it's the screen control, which
controls the bias on the screen grid. It shouldn't be touched by
anyone who doesn't know what they are doing, although someone may luck
into a reasonable looking picture without knowing what thwey are
doing. The screen may in fact be set properly, and another problem is
causing the dark screen. It could be a G1 short, a weak CRT, and a
number of other things. If you are going to move the G2 (screen)
without the proper measurement equipment (a very high voltage, high
impedance meter or oscilloscope), make sure you mark the control and
the body of the flyback with a very thin mark, to maximize the chances
of getting it back close if it is not the problem.

If you think you understand, read this before trying anything...
http://www.repairfaq.org
Read the stuff on monitors and safety. I did this for a living, and
I'd say you are in over your head on this stuff.

May help, but if the heater filter capacitor is gtting tired, the
extra effort may kill it for good.

Remember...test before rejuvenate. If the test says the CRT is okay,
you're only going to shorten its life with a rejuvenation.

| Your questions and terminology suggest either that English is not your
native language or that you don't know what you are doing.
Understand that unlike any part of a PC, a monitor has voltages that can
be LETHAL, and that persist for some time (many hours, sometimes a day
or more) even after it is turned off an unplugged.
Unless you know what you are doing when working with HIGH VOLTAGE
electronics (tens of thousands of volts at the CRT 2nd annode, thousands
for focus and CRT elements, and hundreds in the horizontal output
circuit), this is not something to screw around with. There are many
hazzards, and they are not all either immediate or obvious. For
example, if you make some of the adjustments wrong, you may end up with
a working monitor that exposes the user to continuous low-level (but
cumulatively very dangerous) X-Rays.

Very unlikely, if there isn't a fault in the discharge path, that
there is anything left in it, especially since, in 5+ years of
repairing monitors, I never encountered a single one that had anything
left in it by the time I got the cover off. However, it is smart to
always try to discharge them anyway; better safe than sorry.
By the way, discharging with a screwdriver presents a big ESD source.
Better to use the proper tool for that.

| Hello guys. I have another (different)problem with my 105S. After turning it on the green LED appears but after short period of time (0.5 sec) it disappears (sometimes it changes to yellow prior disappering). I am suspecting power source or overloading. It occured once before, (but monitor was in garranty) so I think its quite common fault. Before this second failure picture was was quite horizontally stretched after turning on. Any suggestions? Thx. |
