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? |

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. cuhulin |

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 |

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. cuhulin |

I'm not stupid. I'm just inexperienced. 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. -- Dec. 6 (Bloomberg) -- Government officials and activists flying to Bali, Indonesia, for the United Nations meeting on climate change will cause as much pollution as 20,000 cars in a year. |

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. Andy Cuffe |

Andy Cuffe 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? |
