Why don' t you post a picture of the good and bad boards......should help in finding the correct values.

Have you compared the "good" board values to the " bad" board?

Heres some for now, but I need to run.

The one in the middle is what is causing the bright bulb. The other night when I was checking some voltages, I noticed that at times if I bumped the board the light would drop out then come back. I am going to check some connections if I have time.
 
I have been busy for a couple of month to focus on this project. So here is the latest up date and wanted to see what you all think. Last time I worked on this I was replacing resistors and checking voltages. Everything seemed to be going good until I replaced one of the last resistors on one of the boards. Then my light bulb came back bright and I lost my voltages. So I walked away for a bit. Well tonight just to get back into this, I decide to plug it in. Well I haven't checked voltages yet, but the bulb is very dim with both cards in. Could I have just bumped something that could have caused the short until I unplugged it and recently plugged it back in.
 
Ok, I checked voltages last night and everything seems to be on the high. In most cases approx. 10 percent higher. I am thinking tonight I will unplug the boards and double check. If the voltages are the same with the boards unplugged, then I am thinking about those diodes and resistors first in the circuit. Any ideas.

Thanks
