Video Sync Issue #32

Closed s3anami closed 3 months ago

s3anami commented 8 months ago

Occasionally the device will temporarily loose sync and other times completely lose video sync (requiring a reset) while everything else is still working ( I can hear audio and my characther seems to be moving by audio cues). I am using an LG C1 and have had sync issies with the Tang8k device before, although a fix was found there. The other thing I notices is that the Tang20k seems to get very hot and wondering if that could be related. I added a heatsink from a raspberrypi i had laying around to try and help there.

Could be related to #28?

Not sure how or where to check to verify. TMNT was very high pitched in the intro

I have this still with the latest update. I had the similar issue with the Tang8k listed here: https://www.eevblog.com/forum/fpga/fpga-to-hdmi-variants/msg4613152/#msg4613152

Don't know if there is a similar solder-able fix. If I use something that forces or repeats sync like a mclassic it doesn't drop sync.

Haven't seen this lately. So closing.
