Weird Jaguar power issues

$

Hey all.  I am hoping someone with very good jaguar repair knowledge can help me out here.  I replaced U38 and the cap and reg1 on the board however when i hit the power button nothing happens.  Here is the weird part that i cant figure out.  If i bridge the first 2 pins on the u38 on the bottom left if you look at it from the front of the jaguar as soon as i plug in power the jaguar comes on and plays the game.  If i have the power switch on off there is no sound but if i have the power switch down there is sound.  I thought if i just left these pins bridged on the U38 i could just use the jaguar as it is but upon closer inspection.. the u38 regulator got way too hot for comfort.

 

Now my question is.. what is going on here?  Ive looked for broken traces and cant find any... why would the jaguar work if i bridge these 2 pins but not work otherwise?

 

any help would be appreciated!! thanks!

 

Edit :  the pins that i am bridging appear to be 15 and 16 (bootstrap input and a switch emitter) according to this pinout http://console5.com/techwiki/images/9/9d/MC34163-Pinout.png
