WHITE SCREEN

Thank you. Before I dissasemble the monitor, is there another way to:

a) provide an alternate video signal to the bordmonitor (i.e. VGA, component video) so it can be bench tested
b) output video signal for the GPS units to an external standard television or computer monitor (i.e. old CRT, etc...)

I see that others have accomplished the first one such as in this thread.

I bought this from someone on eBay and they shipped it insured. He says he will file claim so I can get my money back. I would like to know certifiably without any doubt that the monitor is not working. Also I am not sure if it is worthwhile for me to dissasemble the unit if I will be refunded or reimbursed for repair.

It's a 2006 unit (246 model) manufactured in 04/05. I bought this one since I figured it would be less likely to be broken.

I would suggest:

Dismantle the monitor and check the ribbon cable from screen to main unit, ensure it is seated properly in its connector. Be careful with the cable, it can be broken and damaged if handled roughly.
Inspect the cable for cracks as well.

Check the all fuses for the system - measure, do not inspect by sight.

Confirm the nav is OK by trying it in another car.

What do you mean by measuring the fuse... Use a multimeter or something?

I think the ribbon cable having loose connection is very possible. The screen is white with radio on or off and I think it stays white even if i disconnect the GPS unit entirely.

I am waiting to see what my options are here first. I think I found a good reference link for dismantling the unit here.
