My system will not power on
Firstly please check the power light on the front of the system. If the light is on then your system is indeed powered up, although the video is not being displayed. If it doesn't turn on there are two common causes of this problem:
1) Defective power adapter
2) Blown internal fuse
To differentiate the two the best option is to try out another power adapter. If you lack a replacement power adapter and have a voltmeter you can test out the internal fuse. If you lack a voltmeter we recommend that you purchase a replacement power adapter and a replacement fuse at the same time as this combination will solve your problem most of the time.

My power light is on, although I don’t see anything on the screen
Firstly, please check to make sure that your cables are indeed hook-up appropriately. If you are using an RF adapter please make sure that you are on the right TV channel. If the cable is appropriately hook-up and you are tuned to the appropriate channel then a replacement cable is recommend. AV cables are easier to use and provide superior video and audio quality and therefore they are the recommended replacement part.

The graphics are distorted or garbled
This can be a complicated problem, which requires some work to diagnosis.
Firstly you need to determine if it is the individual game or the system itself that is causing the problem. The way to determine this is by the number of games that are affected. For instance if all or most of your games display distorted graphics then the system is the problem. If one or just a few games are causing you trouble then the games are the issue.
Most games are garbled
If most of your games are displaying distorted graphics then you most likely need a replacement 62-bit pin connector, although we do not currently sell these. Some sellers have been selling replacements on E-Bay in the range of $15-$20 apiece; however it is important to note that two types of pin connectors are used.
1) A solder on type
2) A snap on type
The best way to determine what type you have is to open up your system and find out. An easier method however is to replace the system. We occasionally have systems for sell on our website.

Some games are garbled
If some of your games are garbled and others play correctly it is most likely because your games are dirty and need a good cleaning. We recommend that you use a Q-Tip and some rubbing alcohol initially to clean the contacts of the cartridge. If the Q-Tip gets dirty then you know that your contacts needed a good cleaning.
If your games are dirty we recommend that you purchase and rubbing alcohol doesn’t prove to be effective enough we recommend our cleaning kits.

My controller’s buttons do not work well or at all
Firstly please check the cable from the controller to the system. Make sure it doesn't have any rips or cuts. If it does you will need to replace the controller cable. We sell replacements on our website

If the cable is intact the rubber pads underneath the buttons are worn out and need to be replaced. Underneath the buttons there are rubber pads that depress every time you press the button. As you can imagine with usage these wear out with time. We sell replacement pads on our website.
