i have a vid game with just a blue screen ..... monitor is good with a different pcb it works fine... tried changing the 2 main chips on this board and still nothing...edge conn was bumped to the connetor once or 2x with power on..... which component should be suspected???
 
It would be helpful if you described what game/board you are having issues with and what chips you replaced?...
 
its a ltj draw poker machine......theres only one board in this unit... I dont have a schematic for it im trying to dig one up .....
the only chips i swapped with known good ones are the 2 game proms after it quit working n still smae condition... ..... i think i blew one of the ic chips having the edge connector on too loose by accident it flickerd a few times n that was it, untill then it worked.......... am i on the right track ???? im not an expert on board component diagnosis or repair but can do it with a lil point in the right direction...
Thanks

Fist thing to do is make sure you didn't kill the power supply, so you will need to measure the +5, +12, and any other voltages to the board. <<<First<<<Check the fuses next.

When you get the power supply checked and verified correct then post a pic of the board and edge connector. It would help to see the board and connector connected, does not need to have power on. Also in which direction the board/connector got bumped would be a tremendous help.
 
power supply is good that was verified with another board .... here is a pic of the one im having trouble with ... while juggling around in there with edge conn loose it slid left n right..... not good.... ..... if anyone can itentify this id like to try to dig up a manual for it as well.


Thanks
