Well with most that use RF it may not necessarily be the system. It could be the TV or a misunderstanding of how they work together. I do not have a PSX RF adapter (I only have the composite ones) so I can't see but look to see if there is a switch on the converter box. This is for channel. Typically channel 3 is the one to use. Then you must make sure you set your TV to that channel. However, not all TVs are the same. It is possible that the TV has a special "channel" to use the port you are using. So if you set the RFA to 3, and channel 3 doesn't do anything, try going below channel 2. Some TVs will have an "input" channel to use instead. And lastly, when you turn the system on, do you get any reaction from the TV at all? Is there a flicker or the sudden appearance of snow or artifacts on the screen when you turn the PSX on?
