why has my monitor suddenly become way to bright, despite setting brightness at 0?
I have a trinitron monitor that has suddenly become way too bright. Even when I set brightness at 0 it is still as bright as it used to be set at max brightness. (The brightness control does work -- it's just that minimum brightness is now still very high for some reason.) I can further reduce brightness by using the my video-card control-panel, which makes the monitor usable with my desktop machine, but if I switch to using the monitor with my laptop I do not have this option, and it is too bright to be usable. Also, there are very faint diagonal (almost horizontal) lines running across the monitor, about an inch apart.
Is there any way to fix this? My monitor has two input cables (for use with two separate machines), and both of them have this problem, so the problem does not seem to be the cable or the machine. The only constant is that I am using a vga-dvi adapter (since the monitor cable is vga). I did try using different adapters but the problem was the same.

yep, that does look like it would solve the problem. I don't mind trying it.
do you have any familiarity with this stuff? for example, the kit that looks most appealing is:
-----
S.Winston has notified me that a kit costing $6.99 + $3.00 S/H contains everything needed. The wires that connect the 'reset' and 'on LED' of an old PC fit both the header pins on both the monitor and this kit nicely.
It can be found by searching for 'RS232 to TTL 5V converter board KIT' on ebay. Or you can check out the kit being sold here:http://www.nkcelectronics.com/rs232-to-ttl-5v-converter.html
This is substantially cheaper with almost negligible increase in difficulty.

but I'm curious about "The wires that connect the 'reset' and 'on LED' of an old PC fit both the header pins on both the monitor and this kit nicely." does that mean I need some other components that don't come with this? also I have no experience building stuff like this (although I have disassembled laptops to replace inverter boards and such things), so I'm wondering whether it's realistic to expect that I will be able to buy the kit and know what to do.
Do you have any recommendations about this? If not I can also ask on the forum linked from that page. Thanks for your help, this clearly looks like the problem I am having.

I'm afraid I've personally never done anything like this either, but I'm pretty sure I'd give it a go, as it's always useful to learn these things (and kinda fun, if you're anything like me!)
And yes that sentence sounds like you need a couple of wires from an old PC chassis. Like you know on a PC chassis, you have that little group of thin cables you connect to the system board for the Power LED, power switch, reset button etc? Those are the ones they're referring to...
I think I'd either look for one that comes with EVERYTHING (possibly some of the ones where they talk about having to reverse the pins but nothing else), or possibly visit a local electronics shop, and see if they have the cables you need...
However, it may well be worth posting on that forum anyway, as I'm sure that way you'll be able to speak to the people that have already tried this, and get some hands on advice on what's required... :)
