Have this sony television that will work great for a couple of hours and then the input (direct tv hooked up to HDMI 1) will cut off and then cut back on. Not that big of an issue but it has increased over the last couple of weeks. Tried different HDMI ports and same result. Also tried a playstation to make sure it was not my direct tv unit.

Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.
I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...11-23-2023, 11:02 PM -
