I have a WG9200 from a Road Burners that keeps losing the color settings. Now all I have to do is use the menu interface board, go to the onscreen menu and readjust the colors and they look perfect, I mean really nice. When I say re-adjust, I set all the color levels even with each other as far as the little bar graphs go. I don't have to overcompensate with one color or another. For some reason when it loses the settings the color levels in the onscreen menu all the levels are different. Next time I power off and back on again, its back to the wrong color settings again. Using the onscreen menu puts it back to perfect yet again.

Is there some type of battery IC or something that goes bad on these that helps to save the settings? It's a beautiful picture and monitor, but this is annoying have to change the settings every time. Can someone point me to the part that gets replaced and how that part saves the settings?
 
Chip IC103 (the serial EEPROM) is bad and needs to be replaced. Be sure to install a socket since this is a high failure chip.

Discussed here:

For the D9200 series monitor, IC103 is Wells-Gardner part # 086X0394-001 Serial EEPROM, 256x8, 8 pin Dip.

Generic numbers are 24C02, KS24C02, and AT24C02.

Jameco Electronics part # 108839 for the 24C02P and it's only 29 cents!

I believe you can sub a 24C04 which is larger memory capacity chip with same pinout, physical size, and current/voltage ratings.

Layton forgot to mention, make sure you do a reset after replacing the chip. Hold DOWN and SEL to get to the factory menu, pick RE, hold SEL until the timer runs out.
 
Just an FYI, Jameco has these on clearance for 15 cents. I know Ken had mentioned they were 29 cents. I guess its a good thing they have a 10 part minimum, which forces me to stock up at 15 cents each.

Thanks again guys.
 
Update: Replaced IC103 with a 24C02 from Jameco, and also put in a DIP socket. Did the reset chip command, and monitor comes up with proper colors every time. Plus I have 9 spare chips now.

I must say, it was a real time killer getting that monster chassis out just to unsolder that tiny 8 pin chip. At least its fixed, thank you everybody for your input and helping me.
