Title: sounds like electrical noise out of my speakers in my top dollar..... Post by: staz on June 03, 2012, 04:49:09 AM i tried everything to make this electrical noise disappear from the speakers....... i replaced board with 504b no change,i tried a harness with 47 ohm resisters, it got rid of the noise but had to put machine to 10 to barely here it ....i took out the lite board to see if that caused the noise, nope still here it..... it looks like the lights from the top box are causing the noise!!!! every time the lights flicker you here it through the speakers......when the board of the top box lights was half unplugged you heard no noise.... the minute i plugged board in all the way and all the leds lighted up you heard the noise........WHAT CAN I TRY NEXT????? :103- :103-

Post by: Yoeddy1 on June 03, 2012, 05:00:10 AM Radio Shack part number 271-1105 - 47 ohm 1/2W 5% Carbon Film Resistor did the trick for me. I set my volume at 7 or 8 and there is plenty of volume. Although you probably have fans running...I don't. Those Barcrest games have noisy topbox fans don't they?
You didn't use a 47k ohm resistor did you? Jason Title: Re: sounds like electrical noise out of my speakers in my top dollar..... Post by: staz on June 03, 2012, 05:04:11 AM yes i used 47k resisters and i had to put it on 10 to barely here it....
