Re: Defective chip on ribbon cables
Shes back from the dead boys its a beautiful site. Was a loose ribbon cable that was causing the vertical line...its been a great project was about to give up instead the knowled ive gathered from this forum is priceless. Deffinetly owe it to u all..so total cost was $306.00 and rebuilt to last a couple more years......
