Dell 1704FPT Screen Goes Blank (BLACK)

Question

My Dell 1704FPT started going blank (black) for no apparent reason (green power light stays on). If I turn the monitor off for a few minutes and then back on, the monitor will work for 20 to 30 minutes before going black again. I've read of this happening in some of the articles in this forum but have never seen the cause of the problem identified. I figure it's a board in the monitor or the video board in the PC that's getting hot and breaking down. How can I troubleshoot this problem?   I'd appreciate any help or ideas. Thanks

I have the same problem with my E197FP monitor.  How was it fixed?

Yep - can't stand the load for too long. Faulty - return it for warrantee claim.

KevinR100 are you saying the monitor is bad? I'll need to repair it myself if possible. It's out of warranty.

larryh Sorry for not getting back to you after that statement. Easy answer if under warrantee;) I would assume it has something to do with the pcb (board) in the monitor OR the power supply also in the monitor. Either getting old & heating up/or causing the heat that makes the pcb 'play up'. Usually, as well, an old monitor will have the backlight/brightness fading & requiring a higher & higher brightness setting. I doubt if it would be the v/cards problem, but it is possible due to a failing PSU or one that is not capable of feeding the power required to the computer components eg. v/card. Vidio cards usually either work or not, but powerful v/cards can get too hot with inadequate cooling & play up. Another symtom of v/cards is 'artifacting' (if you don't know what this is, just google it) but this is usually early after buying them & they can do this especially with overclocking too far. A simple test here is to put your v/card in another machine &/or the monitor. Sorry for being long winded but there you go. cheers
