It wouldn't turn on just by hitting the relay with the stand bay flashing | Q301d5032 shortened ic 301vertical output utc7805 shortened and the r3092r open q606 shorted observe that with these burned components the power supply is blocked and c607 is loaded | I replaced all these components and it was ready again.

HP00068A |
Turning off after supposed power outage. | Right away, I saw that the power supply responsible for charging the battery was inoperative. | When reviewing the power supply PCI, hp00068a (same as the pht3000 and tsound is a diagram at electronia.pt) I found the photo coupler shorted between pins 1 and 2, for this reason I replaced the 431 and the lm 358, it still didn't work. good primary It had +b and pwm power arrived, I replaced the ob2273m with an equivalent and it worked, it generated 14.5 volts on the secondary, I connected it to the box system and it stabilized at 13.5 volts. resolved! pht5000 box ok!!! | Giovani PiresBitencourt |
