I recently picked up an Atari 800xl from ebay that seems really solid and I am using a DIN to RCA cable through an AV to HDMI adapter to connect it to my flat screen tv. This all seems to work except the signal on the TV seems to have a horizontal alignment issue. It reminds me of old TVs where you had to adjust the H-hold and V-hold to get the picture to line up nicely.
On the motherboard, there is a component for the DIN connector (highlighted in the image below). If I take the top off of that (held on by pressure, and pretty easy to remove) there are two adjustable flat-head style nobs. I am curious if those might be V-hold and h-hold nobs. I don't really want to adjust them if it ends up being something else I damage the DIN connector. The component looks pretty old (like the rest of it).
Any advice on how to stabilize the display output so I can have fun with this thing?
- I cannot set the TV to channel 3 or 4 since it is adapting the signal using the HDMI box. Changing the switch on the back of the atari makes no difference.
- I have tried other cables with the same result. So I am fairly certain the issue is in the Atari itself.
