You are 100% correct on the routing of these sets of wires!!

| 31-01-2009 | 53fdx01b | yes this is the problem I'm having. But I can't find a schematic to show where to install chips. |
| 31-01-2009 | | Maybe this will help.
I assume the two surface mount caps go on the bottom of the signal board at the R0C3 and R0C4 locations.
I presume they are currently unused/empty.
The parts list and signal board schematic (1 of 3) upper right corner - show R0C0 |
| 31-01-2009 | sony 3400 v2 | One capacitor c618 is charged through bridge rectifier circuit and the other capacitor c619 is charged through STR81145A(Voltage Doubler).This c619 is getting too much heat when powered on.
With Regards,
Ramji |
| 31-01-2009 | | What is the measured voltage across C619? |
| 31-01-2009 | | Possibility:
-Over voltage at C619 caused by:
* C at pin1 and pin2 STR81145A defective.
* STR81145A defective.
- Bridge rectifier defective ( pin - ). |
| 31-01-2009 | | how, approx much did the board cost? do you know the model/part #? thanks a lot. |
| 31-01-2009 | | Can you get the picture of the power board in the AL1711, I need the same picture of the resistor that the others are looking for. Very important. Thanks |
| 31-01-2009 | | Thank minnie, ichage the stk. but i not sure the value resistors, one of then reading 42 ohms, other 17 and when verify the other circuit the resistor are very low. |
| 31-01-2009 | Need schematic/service manual for Dreambox7020si | Hello,
Maybe anyone have schematic/service manual for Dreambox7020si satellite receiver.Many thanks :D |
| 31-01-2009 | | Have you tried contacting the manufacturer?
Some will cooperate, some insist their units being propriatary.
There's also reverse engineering - draw your own. |
