Rigol DHO804 - Potential issues or normal behavior? Need advice on whether to return it.

Hi everyone,
I just bought a brand new Rigol DHO804 from an online platform. After running it for a bit, I noticed a few issues listed below. Could you guys please check if this is normal behavior or if I should return the unit?

  1. Dead Pixel: At the top edge of the screen, when I run a screen test with a black background, there is a bright spot that looks exactly like a stuck/dead pixel.
  2. Backlight Bleed: Looking at it overall, the screen seems to have quite a bit of backlight bleeding.
  3. Overheating: After using it for a while, the area right under the screen gets quite hot.

Please let me know if these are actual defects so I can process a return or exchange. Thanks!
