At the Time of installation d2h engineer attached A/V Red Yellow Blue cable but due to pixels & clarity issue, I have purchase HDMI cable by self and attach it to TV in HDMI port 1.
At the Time of switching on TV audio & Video working we'll but if i switch off my STB with remote & switch on again by remote itself; only audio is coming video not..I have to do restart both STB & TV then it's working perfectly..

Please Help how to fix this issue..

At first @myselfmks bro Don't use bold letters for whole post.

The issue is mostly with STB, that's why there is problem after using remote.

Bro,Once again adjust the AV/HDMI cable connected on STB and TV...
