I just finished my Popeye to DK conversion. I turned it on and everything looked and played GREAT. We played it all day Saturday at my BBQ. I turned if off that night and went to turn it on yesterday and just got dim, scrambled, graphics, and a continuous wah, wah, wah sound.

I plugged the DK board into my JR cab and it works fine. I reconnected the DK board to the Dk PS and ran the monitor wire to my JR monitor and that work fine. I am guessing this is a problem with my monitor, but the thing was pretty bright and crisp on Saturday. I can't imagine it just going out like that.

The cabinet was not moved and nothing was touched. Any input you have would be great.

open her up, it looks like the neck board is not all of the way on the tube. make sure that the neck board is seated good. (power off, of course)
 
Dokert, thanks. I just took the neck of and reseated it to now avail. I tried adjusting the holds and it seemed to clean the picture up, but the colors are now non existent and it looks like I am getting the jail bars. I guess I will try a cap kit. I hate Nintendo and I hate DK.

Thatll learn ya to do that to a poor popeye!
 
That would be a ground issue on the video cable, could also be caused by the inverter board if you have one.

If you have an inverter board, just bypass it and hook the video cable right to the monitor chassis.
 
Dokert,

Thank you so much. I was wondering if it was the inverter. I don't have a ton of exp with monitors and have been really hesitant about messing with this one. I bypassed the inverter and tweaked some stuff and I have it to the point where the colors are almost ok, but I have jail bars and vert collapse. In addition the image is too wide. I tried tweaking the horizontal pots to no avail.

I have a cap kit ordered and hope one of the locals can come by and talk me through it.

Thanks again.
 
The worst part about doing a cap kit on a Sanyo is taking it apart. Make sure that you verify the B+ is 108vdc after you are done. Also make sure that you do NOT plug this monitor into a wall outlet, it needs the isolation transformer in the bottom of the cab.
