Default Sony Trinitron CPD-100ES

I have a monitor here, I've had it for probably about 4 years now.
Great monitor, perfect color, just the right sharpness, everything is
fine except the brightness.
It's been like this for quite some time, and until now, it's been
tolerable, because it's been connected to an older PC that could
barely handle XP, so I didn't use it much.
but now that I've gotten a faster PC, I'm noticing that I can't even
watch videos, because its so dark.
I've got the brightness up to full, and it's still far too dark. any
suggestions?

There should be a brightness control inside the monitor. If you would
give a model or some means of idetifying the monitor you might get a
meaningful reply.

I'm not familiar with this particular monitor, but often there's a master
brightness control inside near the flyback transformer, usually it will be
marked Screen.

www.monitorworld.com www.si87.com Monitors, cables, adapters and
more.A few years ago I bought a fifteen feet long VGA cable ($60.00 plus
$10.00 S&H) from si87 for my computer and monitor.The cable has a big
torroid on each end of the cable, to help prevent ghosting images.In the
morning, I am going to order a fifteen pin female to female adapter from
si87.

well, I took it apart, and I honestly was overwhelmed. I'm no
technician, and I found 2 'knobs' or something. black things that look
adjustable. I think there was one on the flyback transformer. but I'm
not positive, because I'm not even entirely sure what a flyback
transformer is or what it does. but using google, I got a general idea
of where it should be. but I can't find any labels like "screen" or
"brightness" or anything for that matter.
so I didn't want to experiment adjusting those 'knobs' without knowing
what they do, cause I'd rather not kill a monitor

Whoa, ok back up, read the sci.electronics.repair FAQ before continuing. At
least read the safety section thoroughly, CRT displays can realy bite you if
you don't know what you're doing, you need to learn the basics before you
even try poking around.

Are you intentionally stupid?


are you both intentionally avoiding the topic?
and I don't need warnings. all I said was I'm no technician. that
doesnt mean I don't know safety of working with electronics, and it
also doesnt mean I do not possess a pair of insulated, non-conductable
rubber electricians gloves. because I do. I'm not stupid. I'm just
inexperienced. all I need to know is what is what inside of the
monitor. I know a little bit. like which parts would kill me if I
touched them.

There are some things in tv sets and many other things that the stored
electricity should be bled off first before anybody starts working on
those things.If something sharp pokes a hole in those thin rubber
gloves, that can result in a deadly shock.

You're ignorant, and I mean that with all due respect. Your gloves likely
have a dielectric strength considerably less than the voltage you could
encounter inside a television, and you'd be more likely to touch the bad
places (not knowing which they are) thinking the gloves protect you.

all I need to know is what is what inside of the
monitor. I know a little bit. like which parts would kill me if I
touched them.


Avoid the red anode wire that goes to the bell of the picture tube when
the set is off. With the set on, there are too many places to list.

Most Sony computer monitors lack a screen adjustment knob. They have
to be adjusted via computer software and an interface cable. If it's
too dim to use, chances are the CRT is weak, or there's something else
wrong with the monitor and adjustment won't fix it.

finally some useful information. thank you!
this is unfortunate. unless one of the two knobs I found is a screen
adjustment knob. but if you're correct, than this is unlikely.
you said an interface cable.. is there a way to purchase this or make
one that you know of?
