ThreadText: # SCART To HDMI recurrently loses signal: hardware problem, firmware bug, or else?
  
  (Asked by: username_0 on 2024-03-20)
  
  I just bought a [scart to hdmi adapter](https://www.amazon.fr/dp/B0BTYN8Z68?ref=ppx_yo2ov_dt_b_product_details&th=1). It was not the cheapest as it also acts as a switch between 3 types of inputs : SCART, "3-cable AV", or just HDMI.
  
  My goal is to video capture some VHS movies. Yet, even playing them on the TV fails with this adapter.
  
  Here are the observations:
  
  * Plugging the SCART-SCART cable directly between the VHS player and the TV works perfectly fine.
  * Plugging the same SCART-SCART cable to the adapter and then plugging the HDMI to the TV results in the movie being "shredded": it oscillates between the actual movie and a "No Signal" blue screen
  * The same problem happens if I plug the HDMI from the adapter to a computer:
  
    + on MacOS, using QuickTime
    + on MacOS, using VLC
    + on a PC with Debian Linux, using VLC
  
  Conclusion is easy: the problem comes from the adapter/converter
  
  Some people are just returning the product online, claiming it is faulty, but I'd like to go deeper.
  
  **Personal Interpretation:**
  
  this is not a hardware problem, but I have the feeling that the adapter is actually looking for another channel, as if there was a chance it could find a higher-resolution input. These devices are supposed to handle Game Console and many other things, so I assume it would make sense in those cases.
  
  In the case I would be right, would there be a way to stick to the same channel throughout the movie?
  
  Otherwise, what could be the issue?

  These converters are wired in such a way that they display a blue screen when there is no recording on the tape. But because these things are poorly tuned, they display a blue screen when there is the slightest disturbance in the signal, or what the converter thinks is disturbance.
