It sounds like the resolution the laptop is trying to send is not one of the resolutions that the television can display. TVs can display a range of resolutions, so try changing the laptop resolution, either increasing it (make the pixels smaller) or lower the resolution, try a variety of resolutions, one should work.

Need to locate the jumpers on the motherboard of dell latitude d420 notebook to reset os password


I'm not sure the d420 has a jumper for BIOS reset on the motherboard. I think you will need to remove the small CMOS battery under the keyboard (for around 15 minutes) to reset the BIOS password and settings.

Hi matt d224...
.I included a couple of links to some parts for the D420
**************************************************************************************************************
There is one test to determine if it is the screen causing the problem or maybe the lcd converter.
Plug an external monitor into your laptop and see if the picture is good...if it is then replace the lcd screen.
If there is still no picture then the problem is probably the lcd inverter needs replacement

Unsupported video signal


It is possible that Jewelquest changes the screen resolution to one that is not supported by the TV. I am not familiar with Jewelquest, but the typical reason for the unsupported message is a resolution outside of the supported range. The supported resolutions should be listed in the owner's manual.
