As far as I can see, Mcufriend or LcSoft produce some circuit boards. Then several Chinese assembly houses produce the finished products. In turn, several more Chinese companies sell them via Aliexpress or Ebay. Or even local hobbyist shops.
For example. Just look for 2.4" Shield or Usbasp. There must be hundreds of different vendors of what look like "similar" boards.
Regarding the Green. I have no idea. I presume it is a manufacturing fault in the bare TFT. I suspect that the pcb assembly is 100% ok. Quite honestly, BG, DealExtreme or whichever Ebay vendor sold you the duff board, should replace the shield. In practice, they will either keep silent or ask you to return the shield at your expense.
You can open a dispute through Ebay. You will possibly get your money back. With no replacement. i.e. you gamble with another vendor and wait for China Mail.
