Memory Palace Image Buffer Probrem

2weeks ago,My MP was go bad.
Keyed-out images buffer are not output when the SCAL option is CAM. And cannot use zoom.Only one color is displayed at the keyed-out location, not a continuous image.
I tried resetting and updating the firmware, but it did not improve.
Does anyone know a solution to this problem?

Sorry to hear you’re having trouble. What case/power supply are you using? Are you monitoring directly from the Memory Palace? PAL or NTSC? What is your sync source?

Thank you for reply.
I use MP for 6 month.
Case/Power:TIPTOP μZeus(MP only)
Using NTSC
Sync from VisualCoretex(Another Power supply)
