Just posting to see if anyone has any experience with the following issue before I reseal the LED display cables by baking them in the oven.

When i first cut the system on, it plays normally for about 5 minutes and suddenly I see faint vertical lines and the display splits into two. If I shut the system off and back on the issue vanishes and doesn't recur for however long I decide to play, usually another half hour or so.

Thanks for any suggestions.
