V8 Nova Blue Screen turning green - purple

[HariSd]

Hi,
I recent bought a V8 Nova Blue receiver and after running between half an hour to 2 hours the screen suddenly changes colors into green and purple.
Turning off and on again restores to true colors.
I use the original HDMI cable, even tried other cables without any change.
The receiver is well cooled.
Pls see attached image illustrating the problem.
I'll appreciate your help.

Try another HDMI cable.

Also try the settings for the video AV output in the menu.
It may be too high a resolution for your TV.
Also check the output type and PAL / NTSC, 50 / 60 Hz.
You may need to set the output from Auto to just PAL or NTSC.

If you get stuck where you can not see they added this, or you can try the TV Mode button.

Added fast key to switch video output mode or format.
we try to support some old TV or some signal mode TV
Press menu key to main menu.(Panel show "----")
press Green key to switch NTSC/PAL, the panel will show "PAL " or "NTSC"
Press Stop key to switch the video format
PAL mode : the panel will show "576I" -- "576P" -- "720P"(50HZ) --"1080I"(50HZ) --"1080P"(50HZ)
NTSC mode : the panel will show "480I" -- "480P" -- "720P"(60HZ) --"1080I"(60HZ) --"1080P"(60HZ)
