T28s random signal after changing PA - GSM-Forum

chrisro · 11-13-2001, 21:24

Hi!<br />I've changed PA in two ericssons T28. In one is problem with signal in 1800 Mhz and in another in 900 Mhz. It means that signal flow between zero and full! After 5-10 minutes it's display 'no access' On second band is all ok. What i did wrong? It's PA not enough soldered? Before changing PA phone was totally dead.

regards,<br />Krzys R.<br /> [email protected]
