Video Game Repair/Golden Tee Complete video card
I have a Golden Tee Complete that used to be a GT 2005. While it was still a GT 2005, the screen had little dashes all over the course. Some courses were worse than others. At first I thought something was wrong with my monitor but now am pretty sure it's the video card.
When I got my new Complete board (green), it did not work with my console. Checked and made sure dip switches were correct. Screen was completely distorted and would freeze up. I swapped out my old video card from my GT 2005 and it worked but still with the little pixel dashes. Seller sent me a replacement video card that didn't show dashes when installed but would freeze up within a minute every time. Why is this? Should I try and get another video card and see if this resolves the issue? Thanks!
It sounds to me like the problem is most certainly in the video card. One of the things that i've experienced is that if the video card gets hot, it will freeze the game. That's what the second card sounds like it's doing. Is there a fan mounted on it? Is there a heat sink on the CPU of the video card? It might be worthwhile to remove the heat sink and put a new one on with fresh heat sink compound and even add a fan. I did this on a lot of the GT's that I worked on, and it not only prolongs the life of the card, but it keeps the game running smoothly.
You might also want to check the voltage of the power supply at the board. In my experience, it should be reading about +5.2VDC at the board.
Hope this helps!
