PSP MODEL PSP-1001 DOES NOT IGNITE

Seguir
Hello colleagues I have a PSP in service which does not turn on the battery is fully charged but does not light check with the meter on the pins where the battery is connected and I see that it varies from 0 - 4.14 volts or goes from 0 to 4.14 volts and drops oscillates I mean, when I connect the charger that is a 5 volt MOBO brand and 0.7 - 0.8 amps, it turns on the red charge led but does not turn on the green LED, the customer comments me, also told me that if I worked with this charger ... what do you suggest?

    Hi, good afternoon, what is the operating voltage of that play, since what I know is play two, but I'll try to help you.

    Hello again, I swear, I measure the battery with the multimeter so I can get into the subject. Now I have a little hole. I will investigate about that play. The truth is I am an electronic technician specializing in computers and other devices, but I like to explore new fields that voltage oscila is not good you have to get in search for some zener for example ok buddy.

    Friend Salvador to start the stwich does not work and I tried continuity with the tester and it does not work but I imagine that is different than the voltage varies as I comment in the load center ...

    if it is broken ... bridge it by pressing about 3 seconds and if it turns green the led that is what you will have to replace

    Hi, good night, my partner, the swicht was not my idea. I went for something more complicated as you comment on the load center. Detection of the battery or many things, especially the oscillation of the voltage. I also think that a test feeds from the pins of the battery with a source of the same voltage and capacity of the battery without the charger clear to see that it results comments greetings ok.

colleagues check these images I took I found this detail near this chip the truth was very difficult to join those components also appear to be burned and I made a bridge to see if it turned on the PSP because before the customer commented that only the red led lit with the charger but now it does not turn on when I connect it or even bridge it without the switch ...
