K750 no signal

yorker · 29th Jan 2008, 03:33 PM

need help anybody knows how to DIY repair for a no signal problem? my hp is just 1 year old, K750i, theres not a single bar on the hp...it displays, No Network Coverage and the bar has no indication. Ive opened up the hp, the antenna pins are touching, swapped simcards, resetting also. Sometimes it goes to full bar and then goes back to 0 again. Thanks in advance fellas

Hmm.. Doesn't sound good. Sounds like a broken transceiver.... You sure the antenna's connected properly?

You may have to send it back to Sony or a phone repair shop for a look-see.

It's possible that the PCB has broken connections too. Hmm Had a phone with such problems...
