Dell Inspiron 1564 - Blank White Screen Problem

I have 2 Dell Inspiron 1564 Notebooks that are exactly 2 tears old and both have the problem described in this forum (Blank White Screen on Dell Inspiron 15 - N5030).  I thought that the lvds cable identifed in the forum (available on ebay) was the answer until I realized I did not have an N5030.  I searched on ebay under the "Cables & Connectors" Category for "Inspiron 15 video" but found no result that referenced the Insprion 1564 - only the N5010 and N5030.  I also searched the Dell Site and foound nothing.  Can someone guide me to the correct lvds cable for my machines?  A Dell Part Number would be great, or a relacement part even better.  My daughteer had a problem with a previous Dell LP purchased via her school bookstore, and now this.  I see why Consumer Reports had Dell Laptops ranked the worst out of 8 brands regarding repair history (June 2011).  Any guidance would be appreciated.    .
