if you really want to do it its not difficult to learn how to solder, just check out some vids and practice on an old pcb
Glad you got it sorted.. I'm hoping to do mine asap but need ask a few things...
What's the exact capacitor you purchased from Maplins?
Any chance of uploading those piccies so we can have a look?
Thanks in advance..
is there a step by step with pics for a noob like me? it would help im looking to do this and need all the info including the cap sizes.
theres really not much to it mate.
its just desoldering the relevant cap and replacing it with a bigger one.
if your feeling shaky about the soldering check out youtube on some soldering guides.
before you take the old cap out just check to see which side is positive. the old capacitor might have a plus or a strip on one side. thats the side you want to stick your new long leg into.
apart from that its a standard solder job.

I've a cheapo 30w soldering iron and some standard solder, would that be sufficient or would I need a higher power soldering iron with a finer tip?
Also the pics in the first post were for a REV K board, and after the old cap removed the new cap was soldered elsewhere, Will the same be needed for the REV L3 board?
dsiner: would really like to see some pics!!

Pics are for Rev J & K... L3 was supposed to have fixed the issues, so i dont know if the layout is the same with regards to soldering a replacement cap.
Soldering job is very easy... bought myself a £10 soldering iron from maplin. You can buy different tips to go on the iron, but the ones which came with it were fine enough.
the lower the power on your iron, the better.
and dont bother going out to buy a new tip,
just get the file out and file your curent one down until its sharp enough to scratch yourself.
if you need it even finer get yourself a stainless steel needle and tie it onto the end of your soldering iron with some copper wire. make sure you knot it hard though, you might want to use some pliers.
not only will that give you a finer tip but it will add some resistant thereby decreasing the heat available at the end of your tip
if you feel there is still too much heat coming out of your iron, just get a shed load of copper wire and wrap it around the steel portion of the iron so it absorbs all of the heat.
as far as i can remember. 15w is optimal for surface mount soldering.
as far as solder is concerned, you want it to be as fine as possible,
the best one for surface mount soldering is the one with 5 cores and it has flux in each core with a diameter of less than a millimeter.
if you already have some solder though, dont bother going out of your way to buy some new solder, what you have will 'do'. just use flux to make the solder stick to your capactior and the relevant pin surface on the tuner board.
@g33za - that capacitor should be fine.
Hope that helps,

Thats the one... as long as its 1000uf @ 16v you should be OK no matter where you get it from, or what the manufacturer is... I posted a link in the first post to the cap i used, but for those that missed it, or for people eho want to buy one onlinehave a look here

so i've just tried this on an L3 tuner, put it back into the box and now the box when starting up (at booting stage) reboots the dreambox. I'm pretty sure I've soldering it properly. Any advice please?
Edit: I took that cap off and tried a new one, this time applying a bit of force to push through the hole, this seemed to work and plugging it back into box (without back plate and cover) the box booted up. Reassembled everything and back to reboot cycle.
Anyone care to help me please?

Sorry cant help m8,just posted so you are still top thread so someone else may pick up.
My 800 glitching upstairs but when i had it sitting above my htpc on one of the fan intakes it never flinched.
I would def look at airflow 1st
so removing the new cap and sort of tidying up the solder I reinstalled the original original cap and its now working. So back to square one. Now I'm wondering if the caps I bought from ebay are any good. Maybe time to make the effort to go to maplins...
ouchers.
i wouldnt buy shit like that off ebay.
you dont know what exactly it is.

yeah, just buy a cap from maplins for 60p or summat.
if it doesnt work again you can just replace it with original like you previously did.
if you still manage to make a balls of it just bu a new tuner or consider buying an original tuner.
before you touch your board again, practice soldering on an old computer or something.

Cheers
