Minigun has lost sync

Edit: sorry, think I've posted in the wrong forum.

Hi

I have a minigun supergun advanced v2 which was working until I switched on the LPF (Low Pass Filter). The screen went blank, so I switched it off again. Now I seem to have lost sync. OSSC says no sync, and connecting directly to my SCART TV I get an out-of-sync image just in red.

Does using the LPF switch on the minigun while it's on break something? Any ideas what's likely broken and how I can fix it?

Thanks.

These things need to come with a warning, you should never hot switch anything on the minigun. I have built plenty of these and they biggest issue by far is people hot switching the LPF, which can and usually does fry the THS7374. So yes hot switching is bad.

I am pretty sure yours is one of mine. MiniGun with a Hirose connector. If you cover postage ill fix it for you.

I managed to fix it myself by replacing the IC, but thanks for the offer.
