Re: Vizio Symptoms and Possible Solutions
well... I guess you were seeing things... :-).
I can only go by your observations and how accurate they are. The tests that I suggested presented different "stages" of "stimuli" to the vga circuit into the main board since that is what you indicated was "driving" a different response from the tv. I guess that may not be true IF I understand your recent "observation"... although I am not sure that I understand your "changed cable and nothing else"... but was it plugged into your computer at this point. Basically, vga cabling provides a "multitude of grounds" on various pins along with some voltage (5v) as part of "capability signalling" to help with "resolution setting". The tests / checks of "blank connector", cable but not connected to source / pc, and connected to source provide different types of "stimuli" to the main board which might tell you where to look depending on which stimuli causes a response... which appears now that isn't happening at all. Does the hdmi cable act the "same" as you originally posted?
