Default 6400 bell hd

I was having problems with my HD 6400 from bell. I took the cover off and found a capacitor C141 went bad. I replace it and never had any problems yet. The capacitor is 820uF 6.3V

Electrolytic caps can dry out over time, or be damaged by over voltage excessive temperatures or excessive current draw in that circuit, the tops of the caps should be nice and flat, one that is bulged up is or will be going bad.

I tend to replace the cap with one that has a slightly higher voltage rating, this will keep it from being damaged again.

If you have an oscilloscope or a good DVM you can check for excessive AC ripple in that circuit, (it should be less then 200 mV AC) and also what the DC voltage is on that circuit, if within 10% of the caps rated voltage you may have a DC voltage regulator problem in that circuit.

In most power supply circuits the caps rated DC voltage should be one and a half to two times the DC voltage needed for that design.

If that circuit is running at 3 VDC and the cap is rated for 6.3 it's a safe design, if the circuit is rated at 6 volts DC and the caps only rated to 6.3 it's not a good idea.

Default 6400 reciever not seeing satalite

my 6400 receiver is not seeing the satalite, I have tried other recievers on the same cable they work find, when you look at point dish from the 6400 it doesn't get a signal. I have powered down and back up, pulled card and reinserted, deactivated and reactivated receiver. Is there a reset or is there something else I should try?
