Re: Do the RB's work.

They aren't connected together. Q801 have pins 1, 2 and 3 together, and they are connected in katodo of the zener diode D803, and the pin 4 is connected to anodo. :? I know, I meant short-circuit between pins 1-2-3 and 5-6-7-8 http://img713.imageshack.us/img713/2368/soic8.gif but know I see that 1-...

Re: Do the RB's work.

Rafaela, wich equipment do you have to change Red and Green components ?
I use Hot Air and a Soldering Iron.

The red I remove with the hot air, and soldered a new component using the soldering iron.
The green(CPU) I just warmed the component.


I helped you with something? *-*

Re: Do the RB's work.

Generally bad capacitors have a curved top, or they can even explode. This is why there are small breaking marks on the top, to avoid too powerful explosions. If electronic circuits didn't had chemical capacitors, they would be at least ten times more reliable in the long term. I've found some bad ...

Re: Do the RB's work.

No boot is often a power problem. Check chemical capacitors. 90 % of problems do come from them. Dissolder and check the value. 1/2 original value is generaly ok. 1/5 or 1/10 is not ok... In my city I don't find any capacimeter. So I'm buying by a store in anothe city. When the capacimeter arrive, ...

Re: Do the RB's work.

Yeah Rafaela. You are right. There are plenty of problems i run into that are not covered on the repair manuals of the distributors. The question you are asking (about nothing showing in winbox) has happened to me many times with the new version of the RB411. I solved it by changing the ether chip....

The blue components are changed to do the RB turn on. The Red components are changed to me connect to Ethers. T...
