How to fix the blinking light or gray screen problem with your Nintendo Entertainment System (NES)

Having a blinking power light or a gray screen is a very common problem with the original NES systems. Fixing it is as easy as ordering a new cartridge slot from the internet and being able to use a screwdriver! Check out this video for more info.

Have a gray screen all the time when I push the tray all the way down. Got a new connector and still have issues

Where did you source your connector from?

Hi there, thanks, I disabled the lock out chip and it just gave me the grey screen. Where can I buy the 72 pin connector replacement . Which one do you recommend ?
