Lenovo M70z thinkCentre LCD & monitor out tidak bekerja/mati



Tak terasa tahun 2011 sudah terlewati, lama sekali saya tidak mengupdate blog ini, sebenarnya banyak hal  ingin saya tuangkan di sini salah satunya kasus computer dekstop lenovo M70z yang gejalanya lcd dan monitor out tidak menyala alias gelap alias tidak bekerja tetapi pada saat computer booting suara welcome window 7 terdengar,,,.itu menandakan bahwa os bekerja normal,,. berikut cara mengatasinya,,.
  
 
 
perhatikan gambar dibawah ini

vcc ps stby yang ketika mobo di hidupkan vcc atau tegangan pada pin ini selalu ada, klik gambar untuk memperbesar, sedangkan vcc video onboard output ps on akan keluar tegangan vcc apabila ic ps on di input ps on terdapat tegangan pacu yang artinya ic sebagai switch untuk menghubungkan antara vcc ps stby dan vcc video onboard, cek pin ic antara input ps on dengan jalur pcb dengan avo meter, kasus yang saya dapat jalur ini putus,, sulusi jumper n resoldering,, dan masalah selesai ketika dites lcd lenovo M70z menampilkan warna yang ceria,,
semoga bermanfaat,,.
