Pioneer DEH-3050UB does not work neither the cd drive nor the usb
The voltages of VD CONT pin 22 and USB CONT pin 24 are missing, measure all the components that are related to these lines, and if all is well we will try to replace these voltages and see if it works, but check well and there is no short That is blocking these voltages.
Amigo Milflo, I already passed that information on pins 18 and 19. according to the diagram
CN701 = 1 = 7.2 V, 2 = 7.2 V, 3 = 5.2 V, 4 = 5.2 V, 5 = 5.2 V, 6 = 5.2 V, 7 = 5.2 V, 8 = 5.2 V, 9 = 3.2 V, 10 = 0V , 11 = 0V, 12 = 0V, 13 = 0V, 14 = 0V, 15 = 0V, 16 = 0V, 17 = 0V, 18 = 0V
Already remove the ic and make the bridge between pin 4 and 5 the voltage arrives but does not read the pendrive
In the cn803 I have 5.2 volts in pin 2 but in 9 only 3.5 volts should have equal 5.1 according to the diagram
Sometimes the servo circuit of the CD card or some other circuit is damaged and it seems that it is happening, I have had stereos with the fault that the mechanism does not move and the solution has been to change to CD card, these are The Kenwood and Sony brand.
As soon as the USB can read it, it is necessary that the information contained in the USB memory passes through the CD card and thus be able to play the melodies.
In conclusion you will have to try another card that goes under the mechanism, which is the same as you have.
And the flex tape may not also be causing that failure? Does the CD mechanism have to be placed in order for it to read the USB?
That must be so I have it disconnected because if there is voltage in the usb, would there be no problem leaving it working without the ic251?
the cd does not work now only tuner and usb hahahahaha what a problem with this equipment
Milflo said something there to qualify as a solution, the client told me that the CD does not work, it seems to me that it is the mechanism that is locked but the issue can already be closed. thanks for your help my pana!
