Redlight of Death Repair

hi mate

pm you details

regards

Cheers buddy!

Fix worked here too

Thanks bluepeter fix sorted my box out also.

Great post!

Going to have a go at this and have begun stripping down the vu+ duo. The motherboard appears to be held in by card reader......am I missing something obvious to get the motherboard out?

 

[micscave]

From memory you need to push the card reader out through the from of the case & you also need to unclip the front facia panel too.

 

[pathfinder]

Cheers, will try that

Perfect, thanks.......Removed facia and out it came!

lots and lots of screws in little neat piles now......hope they all go back in the right place

In the end I couldn't unsolder the cap from the board, I don't think my soldering iron was getting hot enough. I just cut the legs of the cap and soldered the new one onto the legs that are left sticking out of the board. I needn't of removed the board in the end. Also make sure you have the cap facing the right way.

That's the way many people did it.

Finally got a chance to finish it......as with micscave I was unable to remove the old solder, so cut the old cap off and soldered the new one on top of the legs sticking out of the board. When I got all the bits screwed together again it powered up fine and is as good as new again.

Great info everyone thanks - as indicated in thread don't bother dismantling the receiver to desolder the old cap.

Hei everyone. Would capacitor 220uF 25V work instead of 16V? have no clue about electronic and dont want to destroy something more

 

[satcat]

dunno m8,, just done one of these today, and it sorted the problem,, probs better with the right one@ 40p of Maplins,,, cheers satcat

snellas

That will be fine. Just make sure you get the polarity correct.

 

[DrProzac]

Just replaced mine and it's all working now.

Many thanks.

I couldn't desolder the old one, so it's just solder on the old ones legs.

I used a 220uF 35v so hoe this will be ok?

I have measured some voltages on the IC's

I replaced mine but still the box won't boot up.
My Vu+ Duo would not boot up, the morning after a thunderstorm night. Hence maybe a high voltage thru the LAN card (its green light turns on normally)??

The guy at the repair shop says that voltages coming out ot the PSU seem to be normal. But he says that processor seems to be very hot.
the metallic plate on top of the processor s very hot - you can not keep your thumb for more than 2 seconds. Is this normal heat for a box that s stuck in stand by? :O Maybe the processor is dead? :/

If so, I would need to change the whole board?

cheers

More likely a high voltage (EMP) came via the coax.
It happens more often that also the voltage regulator oges belly up if the famous capacitor is in the process of breaking down.
The processor is always very hot.

 

[abu baniaz]

Any pictures / precise location of this regulator?

Many thanks Rob for your reply - I almost ordered the whole 'motherboard'.
Before I order this voltage regulator in the site you pointed out, how can I test it if it really that one that needs replacement?
(I know it sounds like a stupid question, but here where I live the TV repair shops are not that capable of fixing these kind of STB... :/ )

cheers
