Do not worry, we'll all busy wink

About DreamBox fixed in ethernet lights, as usual, it is not connected by putty, unresponsive. Tensions are all correct. Even the cap appears c115 me 3.3v voltage
There's some checking .... Is there a solution?

On the other dreambox, effectively lights on and off, I will check voltages

ThanksJohnny_B

The box which is completely dead, only the lan LEDs.

Check the ohm values of the P5, not the voltages, so do not connect the psu.
On this picture you see three rows of ohm values of three motherboards.
Check whether one or more has a different value.
All values has been measured between the ground and the measure point.

Pin 4 issue?, no this I've seen more often while the receiver worked just fine.

The rest looks to me fine.

I think, replace the four big caps then there is a reasonable chance that the box again works.

The one who does nothing, only the lan leds are on.
And with or without a network cable connected.

4700uf10v? Replacing four caps? .. Indeed.

Hi Johnny, I do not understand well. (Google translater)
I have to change the 4 caps of the dreambox with fixed lights in ethernet?
My question is the 4 caps are 4700uf10v? You have any photo to see it clearly?

It concerns the receiver with only two LEDs on, no further activity.

And it concerns the 4 4700uf 10v caps that needs to be replaced.

I fixed last night a friend DM800HD box, replacing the 4 CAPS, the box was even not turning on... ! And now it works as new with the new 4 x 4700uF caps.

I confirm it's a very good way to fix most of the dead DM800HD.

It can be 13 x 26mm, so these 13 x 21mm are the correct ones.
And so yes.

The Rubicon caps are quality caps but the others are also good enough.
It's just a matter of choose.

Hmm okay, so there is nothing changed.
You still have a death box, with only the two network leds on.

Based that you have replaced the four big caps.
That you have all the main voltage on the P5 pins.
http://jb8a8f8.com/support/index.php?attachments/dm800hd-fault-finder-pinout-2013-jpg.21/

The main ohm values on the P5 pins are also fine.
http://jb8a8f8.com/support/index.php?attachments/dm800hd-fault-finder-pinout-ohms-2013-jpg.23/

So there are no measurable things that tells that there is something wrong.

Than I'm afraid it would probably a cpu problem.

Yeah well sometimes it's wiser to stop with the repair before you spend too much money on it.

But the only thing that it maybe could be.
Is the removal of the U18 - TL7702 ic.
The motherboard can work without it, and can give this issue.

However it's a small chance.
