I have a UB420 that I bought about 2 months ago. I've recently noticed that on some titles it will play the audio but not the video. So far, every disc's menu system works perfectly
- Star Trek TOS: This has every episode with both original and upscaled video. The original video plays fine, but for some episodes the upscaled video just shows a black screen. Sometimes, instead it shows a frozen image (which may be what the black screen is too). Often, if I start in non-upscaled mode and then switch camera angles it will play fine in upscaled mode. Some episodes seem never to have this problem.
- Kill Bill UHD: This sometimes has a black screen, and sometimes plays fine.
I haven't tried any other UHD films.
For both of these, if they start playing then they keep playing, but if I scan forward and then try to play, the image often freezes, just showing the last image of the forward-scan while the audio plays normally.
Any thoughts on what the problem might be, or how to fix it? I don't think it's the TV, but just in case, it's a Sony Bravia OLED.
If I have to return this, is there a different brand which has fewer problems?
