VU SOLO4K, Reinstalled to 6.2 and I got "flash problem". It makes very probably always - online watching, watching recorded files, watching NAS files, watching just paused playing........ sometimes often, sometimes never.

The "flash" looks like one bad frame. I recorded it to my camera then I found that "flash" as some strips - see enclosures.

Does anybody know why it is? Formerly with version 4.0 absolutely no problem...... for sure I checked HDMI cables but no change.....

Never seen this on my Solo 4K. It smells like a driver issue. You could try flashing 7.0-rc, it has newer drivers.

Me neither with my solo4k. Is it also with normal TV watching (DVB)?

Strange have you tried with another HDMI cable?

[Jantars]

Yes sure. Diferrent cables, diferrent TV sets, diferrent source of signal (Xbox One). I tested tens of HW combinations in excluding way and my final conclusion is that there is sometning vrong with SOLO4K SW or its settings, but I still do not know why. As far as I can say when I change settings to 720p problem disappears.

Big problem is, that I need long time for testing - the problem is not regular. Imagine that for 2 days is everything ok and then suddenly I can get the trouble, sometimes many times per minute. But when I cange something, typically switch off/on receiver, SOLO4K or TV set or just reconnect any HDMI the trouble dissapears immediately. Very strange, but after big testing I am convinced that there is something no good in that OpenPLI version. just now I keep 1080p and playing with another settings, like frequency 50/60Hz (excluded), HDMI color etc. I will see and then report.

I don't think that OpenPLi is the culprit otherwise many people will have reported this bug too. So far you are the only one reporting it.

So I am rather thinking of a hardware defect on your Solo4K if the other sources that you test doesn't generate this problem we then can exclude a TV or a HDMI cable problem, the remaining element is the Solo4K.

 

For your information I also own a Solo4K connected to a Sony TV and I don't experience this problem.

[Erik Slagter]

I also think a hardware defect, the HDMI transceiver having had a blow someway.

[Pr2]

Just one other idea what is your signal strength and quality, perhaps that problem occurs when your tuner become hot.

[Jantars]

Maybe I can check the tuner. I understand that there are no no more known people reporting the issue. But one strong reason to exclude HW failure of the VU+ box itself is, that I run it for 2 yrs without any problem, then after clean install OpenPLI 6.2 I started to got this problem. And the only  hw change was, that I touched VU+ box to connect/unconnect flash disk.

 

I need more time to understand what it is, then I can post more......... meantime maybe somebody else will got the problem.......... and if I will not solve it it still to be possible tu set 720p only which is degradation but for 42" it is not crucial I suppose.....

[Pr2]

Your conclusion to exclude HW failure is wrong. Few years ago, I had a Xtrend ET-9000 it was working really fine, then OpenPLi 6 was released I flash it and it was no longer working, of course I was thinking of an OpenPLi 6 defect but it was not, the capacitors in it just die. To flash I need to power it off/on and the capacitors doesn't support it and die. I replace them, flash again OpenPli 6 and no more problems.

So electronic can be defective too, and a simple power off / power on can make some weak component to fail.

[Jantars]

Yes, thank you for your opinion. If I will not remove the issue I will return back and start to solve HW again........ BTW A/V settings in VU+ I kept 1080p, put directly 50Hz (before auto) - still problem. Then next suitable item for editing is "HDMI color spaces" (my translation from local language) and re-set from auto to YCbCr420 - still problem. Re-set to YCbCr422 an it seems to be OK now - more than week....
