Question Is it my TV or is my Set Top Box going bad ?

Hi.

I will try my best to describe my situation.

1) I switch the mains of my TV using the switch on the wall.
The TV turns ON in standby mode because I always turn
it OFF using its remote.

2) I switch on the mains of my Set Top Box using the switch on the wall.
The Set Top Box starts booting immediately because I don't turn it
OFF using the Set Top Box's remote.

3) I turn ON the TV from standby using its remote
I get display on the TV and I see the Set Top Box
finishing its boot process and finally I see a TV
channel.

My problem :

When I want to turn OFF the TV for a short period of time
say half an hour I turn it OFF using using the TV's remote
and it goes into standby mode.

Note : The Set Top Box stays ON. I don't turn it OFF.

When I come back to watch the TV again I turn it ON using its
remote and it goes from standby mode to power ON state
but I see

"NO SIGNAL"

displayed on my TV after switching it ON from standby mode.

What I do next is switch OFF the Set Top Box from the main supply (A.C.)
and turn it back ON.

After say 5 to 6 secs the "NO SIGNAL" goes away and I get the signal
from my Set Top Box back again.

Is it my TV or is my Set Top Box going bad ?

Note: The above mentioned problem does not
occur all the time. It only happens sometimes.

To me modern devices are designed to be left on standby and you are doing your own funky stuff to them.
