As radio has no tx or rx at all and you have checked voltages and seems OK, I would center the effort to check if reference oscillator (10.240mghz usually) is present and if vco is generating the right frecuency. If pll is not generating its frecuency, it kills your tx and rx as band pass filters won't let pass RF in rx area or after mixer in tx.
I think it is a good starting point to check as vco frecuency is necesary for tx and rx.
Good luck mate
