Ya I get the same result too. but it is offline product and it is offline after entered to cart and cant be downloaded additionally it doesn’t show up for 2015 and 2015 .

offline means it has to be provided from the long term archive first. Please see here: ESA Copernicus data access - Long Term Archive and its drawbacks

A student was doing a fairly standard cal process, then speckle filter (standard Lee settings) and got a black screen with a few white specs for VV. VH fine. As suggested below, I loaded “Colour Manipulation” and saw the automatic dynamic range had failed. I used “Manual” in the tool to select a range of 1 to 40000, and the image appears. The slider option does not work…too sensitive. Maybe the Lee filter has huge values due to divide by small number or something. The “Manual Edit” option is also not great code i.e. typing in the min/max is hit and miss.

I agree that the color manipulation could be more elegant, but at the end of the day all of its fuctions do work.
If the image stays black upon first loading there might be a problem with the tile cache setting, but this is just a guess.
