Humax displays 'synapse' when trying to view video. sound is ok

As it is so new, your best option is a replacement from Humax. This is assuming that you are sure that the signal to the unit is OK.

Have you tried pointing the remote at a digital camera? This will show the infra-red signal coming from the remote. If the remote is OK, it may have been set to an alternative mode.

This is sometimes due to the PVR not communicating properly with the TV. Try turning the TV on before the Humax.

i can resolv that problum

Connect by Ethernet cable. If still buffering too often get a faster broadband.

So you have HDMI off of the PVR into the TV and AV off of the DVD Player into the PVR at the moment? Just for info what connectors do you have at the back of the tv, dvd and pvr? In's and out's...

Time for a new machine I think. Sounds like corrupted memory - fortunately the loader is still working - so you may be able to do a software update. So search the web to try and locate the last software update image and apply that using a laptop, with a USB to Serial converter cable, and the Humax windows firmware update tool. Not sure that any of that is still around given the age of the machine

I , would try using another ( alternative connection) from your humax , say the scart cable just to see if it , the humax is ok. then if tv has more than 1 hdmi skt try it too, if still not working retry upgrade firmware route

If it new take it back for warranty.

Power cycle the unit. See if the works.
