8250 no signal

[Leochngyh]

My Nokia 8250 has totally no signal but sometime when switch on the phone, the signal reappear but cannot last long. I tried to clean it in IPA (alkohla) with untra sonic and the problem was fixed but the line quality is very bad. I tried again and now the phone had no signal again. I tried to soak it (Ultra sonic with IPA) several times but the problem still same.

Please help
