LCD issue

#1 Post by mybellyisempty » Mon Oct 09, 2006 6:16 pm

Here's a theoretical question for you guys.

let us presume I have a T42 and a T43.

The panel on the T42 is better than the T43 (same resolution, but better color.) say, the T42 has an LG, and the T43 has a Samsung.

During an attempt to swap the LCDs, the T42 display is put into the T43, and, after showing light at first, shows the display.

But, when putting the T43 panel into the T42, it displays, but does not activate the backlight.

Putting hte T43 panel back in the T43 results in a working machine, but now the T42 panel does not work at all. Putting the T42 panel back in the T43 shows light, but doesn't show information.

Would this be indicative of the inverter going out? If the light comes on at all, I don't believe it'd be the backlight. Any other possibilities, other than the panel having gone out?

Use a magnifier to check the pins of the lcd connector maybe you bend one.

Good luck!

Let's assume I didn't, and that the plugs were normal.

Then,

It doesn't make any logic something must have gone wrong, the two lcd's were working prior the replacement.

The cables or maybe the lcd must have receive any kind of damage during the swap.

Logically, something *has* to have changed to an inoperable state during or shortly after the LCD swap. I can't really see how anything other than the cable for the LCD got damaged and resulted in a fully lit screen with no data being rendered. Obviously the backlight works and most likely the inverter on both systems are functional as well. :)
