This looks challenging especially without lots of equipment.
1) if you have an old game or VCR try that through the RF.
2) if you have no inputs hooked up is the OSD stable ?
3) try tapping ( with authority ) the set & see if that effects it.
4) if the manual has a block diagram ( not the schematic ) post that.
It shows the flow from stage to stage & is a BIG help on high end sets.
5) DO NOT go into the service menus at this time !!!
6) when you pull the back take a chassis picture. That helps us remember
a set.
Let us know what you find.

Hello sir, Thank you for the suggestions.
1) Unfortunately no
, I do not have anything that outputs RF anymore, they got thrown out a long time ago
.
2) The OSD looks to be nearly perfect , a bit fuzzy if someone looks too close for any problems.
3) Tried tapping/hitting actually at the back it went from current to worse on one of the channels (AV3) .
4) I've scrolled up through the service manual and I could not see a block diagram
.
5) Ok, Gotcha loud and clear.
6) I'll try to take some pictures tomorrow right after work, my apologies for the delay here.
I'd like to add highlight on the Component input with an OG Xbox in the picture below
I apologise I was not very helpful this post , Please let me know if you need any more information or specific demonstrations I need to capture (video/images) or measurements with a multimeter in specific areas , Kindly note that I currently have no idea how the CRT TV is divided into (Blocks) and what are the voltage levels I need to check and test if needed.
