    Thanks for your suggestion. of course i have tried more than 5 cables.
    - I removed it to measure the voltage and temperature

    Did it stopped working suddenly or during some experiment .If CVBS is working fine then check the lines coming from processor to HDMI & parts in them if they are good ..issue may ..may be from processor itself

    And, since there is no ESD Protection for HDMI, which in this case the not present P901/902, then there is no ESD protection between the Hdmi connector and th CPU.
    Thus therefore there is the risk of damaging the CPU, Hdmi section when plugging in, or out the hdmi cable while one, or both devices are active.

    So, this may be the case however, check also the Hdmi connector, check if it has no damage pins and it may also still be software related, as also it may be wise to test it with another hdmi monitor/tv
