Question about Sega Dreamcast Console
The most common reason for this happening is dirty power board connector pins. Follow these steps to try and cure it but if you not happy with playing around in circuit boards do not attempt it!
Step 1. Disconnect all cables from the dreamcast including the power cable!
Step 2. Remove the dreamcast modem and take out the 4 screws in the base.
Step 3. Take the top of the dreamcast off. On the right hand side you should see the power board. Disconnect the cable that goes to the power board with a white connector.
Step 4. Remove the 2 brass screws securing the power board.
Step 5. Carefully lift the power board away from where it sits. You should see 6 pins sticking up that normally connect onto the power board. These are the pins that become corroded or dirty. Give these a clean and then re-assemble in reverse order. When replacing the power board onto these pins be careful not to apply too much pressure.
The other rarer problem is the firmware chip has become faulty. Under normal circumstances the dreamcast will run with no problems following the set of programming instructions that are written on the firmware chip. If this becomes damage, either by electrical surge, excess static or simply by age degradation then the machine will basically not know what to do. The reset is the product of this.
As to fixing it, it would be extremely difficult as you would need to locate which chip contained the firmware and resolder a new firmware chip onto the board. Most of these components are surface mount technology and need special machines to attach them to the board.
If the power board connector solution does not work then you are more than likely going to need a new console.
