Re: Destroyed LVDS cable for Dell 2405WFP

When I said hacky, I wasn't just referring to his fix. There was one other I saw that truly was. I will admit, the repair kazkasneaiskaus did does look nice and neat, but from an electrical engineering point of view it is a hack since it throws away the differential signaling and carefully designed line impedance you need to keep good signal integrity for those high speed data lines. That's why he had those issues with artifacts on the screen. But, like you said, if the point was only to demonstrate that the monitor works, it was quite successful....

Thanks, looks like I'm not the only one is this boat. Not sure if I would have found that or not. Oddly a forum search for dell lvds doesn't bring up that thread - doesn't look like he used lvds anywhere. Now melt cable does, but I had to know that was the terms used in that post.

What's really got me interested is how this cable got hot since it isn't located near anything that should be particularly hot. The power supply is located well to one side of the logic board on this monitor. Unless maybe that backlight gets warmer...

I have an interesting problem. I have a Dell 2405WFP monitor (acquired second hand, history unknown). It had the usual problem with bad caps, which I fixed. It also appears that it took out one of the converters on the logic board (loads the 19V supply (checked with no load) down to about 14V if I connect the logic board, fails to power up when connected, etc), but I need to troubleshoot that further. I'm not really that worried about that since it seems to be fairly common and I work on DC-DC converters for a living.

The interesting problem is like this. The LVDS cable on this...
