If you have 11.2V at pin 9 of the PLL, most likely it has taken out the PLL too. It doesn't always happen, but I am willing to bet that the PLL is bad as well. Replace the MB3756 regulator first, and if you get 8V at pin 1 when you're done, and 8V at pin 9 of the PLL and you still do not get TX/RX, the PLL has gone fault and will need to be replaced.



Hope this helps!
