Does not turn on, only in STB | Regulator h, cv | Equivalent, replacement, replacement of the aoz1031ai, I replaced it with the aoz1073pi and it worked well, all that replaces is the switching frequency, but nothing significant. | Davi.sls |
| PHILCO |
PH1700BT
|
Turning off by itself, sometimes it takes a while to turn on | Change the micros! the defect is just one, but I always change them all! | Replace all computers (rodrigo cofferi) | Rodrigo cofferi |
