How do I connect this flat panel screen?

[tonyw]

I was just given a flat panel screen. It's a Dell, no model number, but "Technology by Philips". It has two signal cables, one with an SVGA connector and one with .

It's faulty, gives a white screen but no video or menu, even.

What gives with the two cables? Should it respond to input from either? Or do both have to be connected for it to work?

Looks like I'm going to learn about TFT screens at last.

No, there's no menu or diags display, only the flat white illumination (back light?).

I just wanted to be sure that it should work with SVGA only before I pull it apart and start looking for obvious faults.

With no display at all, it looks like a pretty basic failure, it just MIGHT be something I can fix.


Re-reading your reply, do I get the impression that the DVI input is not scan rate sensitive? Or does it still have to have an appropriate scan rate for the DVI input as well?


Thanks

Well, I pulled it apart and found nothing suspicious (as you'd expect). There was a suspicion of sticky stuff around the edge of the screen, so I dismantled the display carefully and cleaned it internally. No evidence of stuff getting inside it though, and I wasn't surprised when I re-assembled it and it still didn't work.

However, a use for the dead machine has now been found. I'll remove the active screen from in front of the backlight panel and my wife can use it as a light box for her craftwork :-D

Hi Seehund, long time no see ;-)

No, it's only connected to a PC laptop so far. I went through the early stages with a CRO and confirmed that RGB video is getting through to the big chip, so I'm confident that it's a logic board fault.

That's right, it was given to me because the local Dell supplier had already said it was too old (2000) to repair.
