Cached Map with Zoom Slider problem

[weeyeo]

I have tiled map (cached map service) and dynamic map service on my live map layer but when using both map services the zoom slider bar won't able to zoom out more than 204800.  There are 9 levels in LOD.  LOD(0):204800 and LOD(9):400. 
I would like to be able to zoom out more to show the entire map just like using dynamic map service.  When only use one dynamic map service without tiled map service, it shows the entire map boundary instead of showing the entire map in scale 204800.

Thank you very much.

   Look at the example here

I attached the images for you to take a look.  Actually I am using the example that you mention above.  When my map scale less than 4800 then Aerial photo will show up but I would like to be able to set the zoom out scale bar to something like 25,000 so the entire county boundary will show up instead of just show portion of the map in scale of 204800.
Please give me some suggestions.  I really appreciated that.

Thank you.
