Has anyone used one of these testers?



Are they any good?

Frankly, unless you're dealing with "naked" LCDs in large quantities, I don't see the point.  I did warranty support for the biggest three brands in the personal computer industry for almost twenty-five years, I've lost track of how many LCD panels I've replaced and I've never used or needed such a device.

I suspect you're going to need a wide selection of "interface" cables or adapters to be able to connect the different panels to the tester, unless, as mentioned above, you're dealing with large quantities of a small selection of the same (or electrically interchangeable) panels - for day-to-day diagnosis in a repair business, where each device-under-test may be different, I don't see it being much use.

I have an older version of a tester like that.  I used it when I upgraded the LCD in my LeCroy WP7KA to confirm that one of my LCD panels had died and to confirm that I got the pinout correct when making a new LVDS cable.  Mine came with a bunch of LVDS cables of various pinouts which was helpful.  It's not the most useful tool but it was cheap and it worked fine for what I needed.

I think that would be the necessity, if you didn't have access to spare parts to confirm the fault.

There have certainly been a few times when I could have used something like that. I hate not knowing whether the problem is the monitor board or the panel.
