console junky Posted October 20, 2002 Share Posted October 20, 2002 I recieved this 5200 from a friend that had it sitting in his garage collecting dust. The system has a wonderful picture just no sound but a high pitch whistle. Has anyone ever ran into this issue before ? Both joysticks are in very nice shape, but do not work even after cleaning them. Buy new ones or have these rebuilt maybe ? Any suggestions would be great.

console junky Posted October 21, 2002 Author Share Posted October 21, 2002 No other sounds, I did power on the unit w/o a cart in it to see if the whistle was still there and it was. Quote Link to comment Share on other sites More sharing options...

+Mitch Posted October 21, 2002 Share Posted October 21, 2002 Sounds like a bad Pokey chip. Mitch http://atari7800.atari.org Quote Link to comment Share on other sites More sharing options...

voiddweller Posted October 23, 2002 Share Posted October 23, 2002 Hmm.... thanks for the info, but what in the world is a pokey chip? Check out the 5200 FAQs: " A7 C012294 POKEY This chip is responsible for generating sound, reading the position of the joystick, reading the keypad buttons, processing IRQ's and, controlling the serial I/O port which is accessible through the expansion connector. " You will need to remove the casing to expose the MOBO and then remove the RF shielding around the cartridge socket. Inside, you will find the POKEY! I wish I had a picture. Maybe someone could post it for you.... Quote Link to comment Share on other sites More sharing options...
kevjon1 Posted October 23, 2002 Share Posted October 23, 2002 does any one stock pokey chips (best electronics maybe) if only a couple dollars might be worth plugging a new one in. Quote Link to comment Share on other sites More sharing options...
A2600 Posted October 23, 2002 Share Posted October 23, 2002 that the 5200 does have a loud pitch noise when a cart is not inserted bout upon inserting a cart the noise reduces but you can still hear a bit of noise.... It might just be my switchbox upon the fact that my 5200 is not diplaying colors.. but yeah it tends to have noise when a cart is not inserted!!
