Thanks for the info. You guys talk a different language. Sounds way too technical.
Thanks for the link Hump, after reading the sound issues, this is the best one that fits my problem.
Intermittent Sound Cuts and Shrieks.
After playing a WPC game for a while (5 minutes or longer), the game sound starts to cut out or in some cases it will emit an extremely loud tone that can get louder and louder until the speaker (or your eardrum) blows. If you turn off the game and re-start, the problem will appear again very shortly. Sometimes you can play a while and it never happens. Often the heat sink attachment to the TDA amps can be very poor and cause the amp(s) to overheat. You can feel the amp(s) get red hot. Solution is to simply un-bolt the sinks, re-grease them and re-attach, making sure to use a locking washer or kep nut to stop it from coming loose.
Now I just need to find where these amps are and see what they are talking about.
I will look for the j205 connector also and try that Marty.
I am going to have to buy you guys a slab of beer or something for all this help.
