First of all I would like to thank all the great people out there for their help! To the problem with the aforementioned TV. Recently the tv switches off just a few seconds after turning it on. However, first of all the screen goes green (with a type of black hue on the edges) for a second or two and then wham. If I insist trying to switch it back on, after 6-8 attemtps it finally stays on and functions ok. Any ideas?!

JVC LT-46AM73 LCD TV won't turn on after power outage. ...LCD & LED TV Repair - No Image & Blank Black ScreenFlashlight Test - How to ...
The Main or Mother board is connected with edge connectors and I expect, like mine, there are many poor contacts as there will be on any component that is on a heat sink including the Line Ouput Transformer. Re soldering that lot will restore the set to a good picture again. Hope that help
Thanks for using FixYa. If the issue is with the failed convergence (STK) ICs which needs to be replaced then, it’s not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you’ll have to open the back of the unit and then replace the ICs(STK ICs) which are located behind the black/gray heat sink and also check theresistors as if they are short the ICs might blow again after sometime.

Hi, basically it needs to be receiving a signal for it to operate. eg. with my one i connect my decoder into it and once the decoder is on the tv turns on. good thing with this monitor is that i just need to turn the decoder off and the screen turns off shortly after. hope this helps.
Two things I would check before contacting JVC. In the on screen menu does it have a setting under tuner controls to disable AFC? It sounds like the tuner is seeking the proper channel frequency before it locks it in and displays a picture. If there is no such setting, then I would try a channel autoprogram in the cable mode. I'm assuming you have no cable or satellite TV box hooked up to the set. JVC is usually a pretty good brand name.
