If you have electronnic skills and good tools (soldering iron, desoldering pump) than you could go to the local electronnic store and purches new capacitors (50¢) each and replace them yourself, just be carful not to damage (pull out) the FEED THROUGH'S (small coper sleev in the holes of the board) while desoldering the capacitors... or ask for a good technician preferably a good friend... (insted of mony they usually accept a good cold beer ha!)

Good luck!

If you're TV is under warranty call the
If not than open the back of the TV and look at the motherboard and the power board for blown capacitor's swollen or broken off and replace those capacitor's you can use the same power capacitor or a higher power capacitor.

How do i repair the motherboard when the capacitors are swollen

You need to have fairly good soldering skills to perform a capacitor replacement on a motherboard. There are many adjacent components that are both ESD and heat sensitive. You need to be able to ensure that you replace the capacitors with ones of the same microfarad and voltage rating. Also ensure that you observe the correct polarity. Even after all that, I'd say you chances of a successful repair are 50-50. But capacitors ARE cheaper that motherboards, so if you feel lucky, go for it!

Mobo boots up when powering PSU without pressing power button on case.

What do you mean apparently?
"Apparently, no swollen or leaking caps."

Helping someone remotely?

The top round flat seal on the Radial Aluminum Electrolytic Capacitor is called the Vent Cover.

The bottom round flat synthetic rubber seal is called the Bung.
Sometimes just one edge of the Bung pushes down, and out of the capacitor's case; and this allows Electrolytic Paste to be pushed out.

The capacitor may only be on a slight lean, and a lot of capacitors wind up being that way when installed.

You/they need to L@@K CLOSE.

This really means motherboard in hand.
Not peering at it installed in a computer case, with hardware components, or cables in the way.

The capacitor case could just be slightly swelled up.
Hard to discern sometimes. I use a bright light, and have been known to use a magnifying glass, lol!

I realize it is just an assumption on your part, and now mine; as to if there are bad 'caps'.
But I do go along with your hypothesis.

Obviously (IMHO) the motherboard is at fault.

My MS6398 went dead. It looks like a condensator on the left bottom at the Dimm1 slot has "swollen". Any idea to change and which capacity ? I tryed with a new powersuppy with no result. Are...

Hi there,

if you mean a capacitor has swollen then this is a fairly comman problem and the capacitor in question may well be able to be replaced. Look down the side of the componant and search the internet for one with the same voltage and rating as the one which needs to be removed, capacitors are very cheap to buy, so if you are any good with a soldering iron, your repair wont take long and will leave you feeling very satisfied with yourself.

Hope that this helps.

Open the case and check the capacitors (small cylinder like componentes), over time they get burned out. You'll notice the top part is swollen if they are burn. In that case you'll have to replace the Motherboard, or replace the capacitors

Defective mother board

check all your memory sticks, reseat them in thier slots, also reseat any addin cards (video,sound card, etc.)
I would also have the powersupply checked before i acuse the motherboard..all the lights can come on , and if the power supply is missing one of its' voltages, the computer wont start. causing just what you described.
physically inspect all the capacitors on the motherboard (lil round can looking components), particularly the ones around the CPU fan: if any of these are swollen OR swollen & leaking fluid the motherboard will most likely have to be replaced.

Have 5 swollen capacitors next to cpu. is there any way to fix this. it is still working o.k.

Its a good news that your system is working fine. However bulged capacitors cannot sustain longer. You should take the motherboard to a technician who can replace the defective capacitors.

Thank you for using Fixya.

The main cause behind this problem is :-
2) HDD is taking extra power from SMPS
3) Motherboard faulty Capacitors / ICs
Try following :0-
step 1) Remove CMOS Battery (3V battery) + RAM
and now try to check whether Fan shows same symptoms or not

Step 2) if results of above step is fail then try to remove HDD powersuppy + CD/DVD power supply + Floppy Power supply (in short provide power to only motherboard) and now start the system.

If the result are same
3) then look for any swollen capacitors on motherboard, if they are then you need to replace them.

4) If no capacitor is swollen then check for every bigger IC on motherboard for whether it got excessive heated or not. If yes then you need to do serious operations on your motherboard .
Please not here i have used the word EXCESSIVE HEATED. and noth the normal heated

check to see if something on the motherboard is fried, usually the capacitors are the first to go. look for swollen capacitors (the X on the top of the capacitor is not flat, usually leaking something or just swollen). If so, have the motherboard changed, if it's still under warranty, DELL replaces it for you.

Uncontrolled CPU fan speed

Make sure you have used the proper Fan connection on the motherboard and that you used all the pins in it. Usually it consists of 3 to 4 pins for CPU fans. Does your Fan have 3 pins? If not then it is not compatible for Fan Speeds. Also check your BIOS for Fan adjustments. Hope this helps.
