I have come with some output today, i was able to successfully transmit a video using DVB-T using Limesdr-USB and receive it properly using (QPSK,16QAM and 64QAM modulation),when i kept my transmitter and receiver block disabled(wired connection)also i was successful,but after that when i enabled again i was only able to get my constellation at my TX side but not at the RX side,what might be the problem actually.
Thanks in advance.

Did you use the fllowgraphs from this github link : https://github.com/BogdanDIA/gr-dvbt ?
If yes, can you tell me whether you are able to receive any signal from the receiver dvbt_rx.grc?
Will this setup work in RTL-SDR or HackRF ? If you don’t mind, can you share your .grc file?
can you share with me the solution please , because the rx dosent work with me
do you have the solution please !
