You may have a bad backlight screen power supply board and that is usually mounted in the bottom part of the screen right behind the front bezel. This supply's high voltage to the backlight tube that lights the screen. This is kind of like a small florescent tube that uses high voltage to fire the backlight and is a common failure point in laptop screens. Easy to fix, just pop the front bezel off and the module will be in the center bottom section of the screen. Do a YouTube search on how to disassemble your model's screen and the parts can be found on Ebay. Good luck.

desperate , why that? are you in uSA>???? locations matter.!!! its an old monitor , buy a new one, and end this love of old Compaq's yous posted with on only the word ribbon, why? the cable on the outside, is a round heavy VGA cable. so is not a ribbon so that tells me you took this old monitor apart, right? and broke or lost a ribbon? the only parts for this is used off EBAY. i looked for you, and see none, its old and now rare. 2001 made. 16 long long years ago, and now forgotten by all.. buy a new monitor, its not work spending case on old things. see $60 monitors? here in USA> http://pcdied.com/cheaper.html tell me how can you fix something and beat that price. lacking parts, is impossible.

never put email here ,ever, or get SPAM endless for 100 years. wow. this is an English forum., here I used google translate for you quoted and commented: "I have one problem. Namely, I need to perform an experiment with temperature measurement using thermopar. ????????? I plugged the heaters into the HP 3497 acquisition cortex. I connect this HP via IEEE488 connections to PC via ISA card (iee 488 card). WE DONT USE ISA card today, in USA> and software for this is hard to find in year 2017, The problem is that I can not intimidate that card to work under XP. WE DONT USE XP today in USA it's a VIRUS MAGNET>! Do you have any solution? And do you know a program by which I can read these measurements? I wrote some programs in qbasic. I installed Labview, but it seems to me that it's quite complex. I need some simple program, possibly with visualization. ITS NOT SIMPLE at all to make 488 work. Thanks in advance My guess, is you are trying to use HP-IB (IEEE488) communications, cables ( a parallel 2 way comms) to some ?instruments.? (ask the instrument maker yet) My guess they are long ago no longer in business or the products are long long gone now. why not tell the full information on this instrument./????? makers name, and model # that takes working software on the PC side. (drivers for the ISA, and APPS to run it) the Maker of the instrument would have APP software to run that. ask them? if not, you get to write your own software, and would need the IEEE488 comms library to do that ,and buy it. you';d also need the book in the instrument in order to learn the IEEE488, command sets , and address and data forumats. or its impossible.

NO PC stated no photos posted of SCREEN FAILING. NO OS STATED< XP? , in this case , it dont matter. i sure its a bad screen. 100% why post and not tell the helper your service tag model # HP made 1000s of PC.s not one can we guess, from 1984 to now. you never even told DESKTOP or LAPTOP. the back lamp does not do DATA its only a LAMP. its a bad screen, im sure. is it this PC?> omg, Do know this some PC , there are no spare parts now. if too old and on some only ,used parts that tend to be bad too. if you ask HP what to do they will ask you the same question. WHAT PC"? https://h30434.www3.hp.com/

NO PC STATED xp is a virus magnet , why run XP? The hinge is a switch, ? and failed with hinge, why not use XP power sittings, advanced, in control panel why not just use the power button and shut it off. the overheating is failure #3, and is packed inside full of lent. bad that. in control panel make sure the power button is set to turn off if you program the powe buttion to hibernate then you must use XP start , shutdown feature to turn it off. ever seen control panel. and power settings and advanced? set the lid to do nothing, its broken so..... then set the power button as you wish. btw most XP are infected with virus or worse. and hibenate will not work, getting hibernate to work in XP or any old XP is like a DREAM. all things must be perfect for hiberate work correctly , and all HP drivers installed, matching your exact PC. or it fails. I never use hibernate. its a pain most times. and can also fail to come out of hibernate. use sleep mode its more Robust. your PC is broken why not get it fixed? https://h30434.www3.hp.com/

never ever post phones or email online, wow, that was a big mistake, doing that. and i tried to delete it and cant.. for you.... DO SO NOW YOUR SELF, or bad happens,from this....

"dependencies" like removing a foundation in your home. NO PC stated. ZERO POSSIBLE HELP!!! iS PC over 10 years old, they go back to 1984, why must I guess. >=10year old answers. (i can tell you with model number) if your PC is HP, the F10 or F11 key works the magic recovery HP hot key, you press that at, power on. then it goes to RECOVERY MODE> fix startups files, or do a full restore. this will fail of the HDD is bad, or someone used NON HP CD's to install the OS before. if that is true, is it?> then we use the REAL HP disks , from HP, not disks YOU MADE ON A BURNER. most old COMPAQs had no F10./F11 key. they didnt have that magic, then. some are 15 years old. IF you get it to work, stop deleting files, now. please.......................................! the REFORMAT can kill dead the F10/F11 restore partitions so.... im betting it did. post what PC is is first and we can go step by ittybitty step. no problemo,

The "no signal" message is not coming from your computer, it is your monitor complaining that it is not getting a signal from your computer. 1st thing is to check that the cable from the computer to the monitor is connected, there are screws but sometimes people don't tighten them. Is the computer actually turning on? Do you hear fans, see lights? If you are sure the computer is actually booting, it probably means the onboard video is gone. You can replace it with a cheap PCI video card. I suggest cheap because the system is 6 years old. ATI PCI 1GB Memory Computer Graphics Cards eBay Here is how you install it.

Use a partition eraser on the drive. Note that unless you use a disk like Hirens boot cd and make it an iso and put it on a bootable drive as an image, you are going to have issues with having to remove the drive and connect it to another computer to remove the partition.

wow what a complex post. why not tell a story, use notepad, and type it and paste it here so we can see whats UP? what are you attempting, seems the Projector is dead, right> what cable, did you use a short direct VGA cable. is it VGA> seems yes, you said, Fn-F4 so is VGA my guess is its custom long cable you made bought or? what does this line mean.??? With my Desktop is not problem! i can not understand any of this , and ive run projectors 100s even 1000s of feet, in airports and other huge , venues. my guess is you do not understand video and its limits. you can not send high resolution to a old projector and windows 10 does not run low reso. unless force windows 10 does not run old obsolete displaces or chips at all. now.. they are obsolete... i can list 1000s dead now... can. The DLP projector is a very cool thing,Texas Instruments based magic. but is old and has 1024 x 768 native resolution so to get that to work with XP,.W7, W8 or W10 the latter is most hard, as W10 does not work and low reso. (means not automatically work) you have to force it. (btw, in say xp/w7 go to safe mode F8 and force low reso.) to do that SAY< in w10, you'd rigth click your desktop screen go to settings then advanced display settings click screen pick display setting, at bottom of that screen pick advance settings. then pick above reso. i just did and screen goes SQUARE 4:5 mode. ugly by todays standards. not plug in the projector and press Fn +F4 bingo, out it goes. keep in mind some GPU chips many not allow this. id need to know each chip in each machine used to answer that. if the projector fails now, then try a regulor desktop monintor now at the PC under test VGA port does it doe above reso. yes then the projector has issues. all this done with short 3'ft standard VGA cable as see on back of all VGA monitors use that to test and get that work ing before using wild custom cables, unstated by you... but youve posted before on this setup, have you not.

A crude manual/guide is available here http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c00496280 There are two power supply connectors labeled AT12V small square 4 pin upper left corner and 24 pin rectangular and ATXPWRR1 upper right between memory slots and floppy drive connector
