DELL P1110 repair question

Hi,
I found this wonderful tip on how to repair the over-brightness
problem in my DELL P1110 monitor:

http://geocities.com/gdaewoo_cmc1511b/cpd-e500_dell-p1110.zip

Now... the only problem is that the last time I repaired monitors/TVs
was about 20 years ago. I vaguely remember that there is a high
voltage charge somewhere that I need to watch out (I am talking about
even after the monitor is unplugged...)

Is this still true or are today's modern monitors built to be a little
more "technician-friendly"?

If this is still true, could you please give me a tip on how to avoid
discharge problems when replacing that R459 resistor on the DELL
P1110?

Thanks,
Lynn
 
All TV sets, monitors, and many types of appliances that use electronics
have some risk of power discharge after the power is disconnected. In TV
sets, some of these high voltages can stay present for weeks or more. This
all depends on the particular design of the model. The key is to handle the
unit with caution and proper care. If a service tech had to leave a TV
unplugged for a week to work on it, he may as well go home and join the
unemployment line! This is why he has the proper training and tools to do
the work that he is doing for a living.

The TV's and monitors of today are a lot more sophisticated than that of 20
years ago. They infact use higher voltages, and much higher currents
internally. Therefore there is technically more chance of even greater
injury if not handled properly.

You should find out if this is a legitimate fix, rather than a mod to mask a
real fault that should be serviced.

From your description, I would think you should have the monitor properly
serviced by someone who does this professionally.

Jerry, thanks for your answer. However, it doesn't help me at all
since I intend to do this repair myself anyway and I was looking for
information specific to this model.

I would appreciate any tip that would answer my ORIGINAL QUESTION. If
no one can come up with one, I will go ahead and perform the changes
myself using my 20-year old knowledge and safety practices.

Thanks,
Lynn

Have you tried running color return which should be in the color menu?
You will have to leave the monitor on for about 30 min before you will
be able to run color return. I've saved several recent sony monitors
with this.

Andy, thank you so much!!! It worked! You just saved me from wasting
time opening the case and performing an unncessary "repair".

You are the best!

It's a selection in the color, or option menu of most Sony made
monitors that have a flat FD Trinitron CRT. It causes the montor to
go through a self calibration of the gray scale adjustment. It
displays several solid blank screens at different brightnesses and
adjusts itself so that each gun has the corrct beam current. It's a
great feature because it saves having to use the expensive and
difficult to use adjustment software even after swapping a CRT.

Oh wow.... I swapped a tube in a 17" monitor. The red was way off. I
figured that I had no way of properly making it right so I trashed the
monitor. Ooops...................
