Thanks for all your input and guidance. This how i learn and will be able to pass it along to others. Will keep you posted. If you think anything else let me know. I am retired so I am always around.Well here's to hoping!
Let's see first if the 74LS fixes it, as broken RAM circuitry can cause cascading problems.Can’t trace more. The signal originates from tmg chip goes to IPS then the video signal. It’s a timing clock signal so if that not there I do t think the video will come up good.
Some have. The LS32 for sure. Memory also but still issues.Look over the same points with an oscilloscope to see if they have improved
I send by email let me know if you get it. It’s part of a manual maybe you have that original manual can do a better scan. I am sure the community would value that.Take a break then
