Are you running with the original, or older cables? A lot of the time, this is cable or TV related. First thing I would try is a replacement cable - these are all over eBay and in many gaming stores. You will not be able to get an OEM Sony one these days (new, at least) but the 3rd party ones work well enough considering the resolution here. If that fails, hook it up to a different TV or if you can do so, try to find a projector to make testing this easier. If neither works, it’s usually a connector or board issue - commonly bad capacitors.
