Hey, I'm new to this forum so I just gonna go for it:
I recently tried to measure the clock speed of the HDMI Signal sent from my PS4.
My setup was as follows:
- PS4 connected to mains voltage (with Phase and Neutral, no earth ground connection)
- My Oscilloscope (MSOX3104A for reference) connected to mains voltage with all three pins connected (Phase, Neutral, Earths Ground).
- The oscilloscope probe was connected to TMDS_CLOCK- (GND) and TMDS_CLOCK+ (RPOBE).
- I used a cut open HDMI cable to connect the probe from the oscilloscope to the hdmi signals. (one end was plug into the PS4, the other end was floating).
- Input impedance of oscilloscope was 1MOhm.
To my surprise, after my measurement the PS4 was unable to send a valid HDMI signal to my TV.
I tried multiple cables and a different TV and didn't get any signals.
I also tried multiple PS4 resets with no effect (safe boot, hdmi signal reset).
I'm really confused since I see no way I could damaged the HDMI port with my measurement.
Is there something I am missing? What did I wrong?
For reference, I also asked on stackoverflow but only got some strange answers:
http://electronics.stackexchange.com/questions/186620/hdmi-port-damaged-with-oscilloscope(I also did ask a trained electronics engineer and he couldn't tell me what went wrong)
I really appreciate any help.
Thanks
