CX919II no display after installing rom

[sandriekus]

Hi Guys,

i've bought a CX919II from ****. When i connected the device first time to my tv all worked fine.
the wifi was not fast, so i want to re-install the stock firmware (android 4.4).
i've used the Rockchip Batch Tool v1.7 software. All goes fine but i dont get any view on my tv when i plug the stick by hdmi.

i've tried a lot of roms but all have the same issue. When i connect the stick to my pc, with the FN button pressed, the software see the stick, so its not bricked i think.

on the inside of the case, the menufacture is CYXtech. so i think i've got a CYXtech J22.

can someone please help me with this issue?
