I have a TnF/Hyper Sports on the bench I am trying to get working again. It boots to graphic garbage but will coin up and play in the background from the sounds I can hear which are ok.
I have replaced all of the Rom,Ram and Customs IC sockets with new dual swipes and with re-flow of the 2 daughter customs. It has a new ribbon cable as well and PSU voltages are set to 5.2V
I have tried the test roms and I get a loud horn like sound runs a sec for 3 times then stops and still have similar garbage on screen.
I have been looking at viable solutions but all my checks come back ok for any I found on the interwebs LOL
I hope someone here can point me in the right direction.
