2 SONY TRINITRON NO POWQER AT ALL ONE MADE 1996 OTHER MADE 1997?

I had one tv 27 inches working, somebody game a 32 inches tv same model but bigger screen, will call the 32 inches tv #2
tv 1 was working, tv 2 was not, I switch the power suply from tv 1 to tv 2, nothing happens or nothing appears to happen in the tv 2.
when i change the power suply from tv 2 to tv 1 (the one that was working) I found tv 1 does not work any more, so now i have TWO not working tvs, no lights or any sign of power.
fues ok. electric plug ok.
Any ideas or should i just give up?
