Hello again everyone! I just finished working on my Wells Gardner chassis for my Playchoice 10 Countertop. On the chassis, I replaced the old caps, filter cap, flyback, and the HOT. I verified that all parts were correct before I changed anything. Before this, the picture from the monitor was good, the only complaint was that it has wavy, I.E. looked like waves in a pool.
After the work, I hooked everything back up, dialed it in, and the waviness is still there. Also, there seems to be a momentary flashing between game transition screens, like someone is turning the brightness up and then dialing back down to correct levels. This also causes the screen to jump a bit, just enough to be noticeable, almost like vertical sync is temporarily lost.
I hooked my multimeter up to IC Pin 4 to check B+, and with the initial power up, voltage is around 124V. In the K7000 manual via a flow chart states B+ should be around 123V. I left the meter hooked up, and started a game, and the voltage jumps up to 131V during these transition screens, and then stays around the 128V range. The high range is when the screen brightness looks like it's been turned up temporarily. I can submit a video if anyone wants to see this.
Is this normal for this chassis? Can I adjust the B+ at all? The only voltage pot I can find on the chassis is labeled "SHUTDOWN". Any advice would be great. Thanks!!!
