If it's the caps in the pic I wouldn't worry.

Re: are these bad caps?

They are most likely polys, and they are usually good.

Re: are these bad caps?

It looks like these are Samxon capacitors:

I don't know much about this particular line of capacitors, but Samxon in general tend to go bad. Samsung often use Samxon in their monitors which have a habit of developing problems.

The datasheet says that they are polymer capacitors, so maybe it's worth a try.

Re: are these bad caps?

^^totally wrong. ULR are polymers made by X-CON, who are a division of Samxon. Samxon are known reliable caps.
QUOTE"Samxon in general tend to go bad. Samsung often use Samxon in their monitors which have a habit of developing problems."QUOTE Nope, samxon are perfectly good caps with no problems. Samsung do not use samxon caps, you are getting confused with samwha.
samwha caps are know to go bad. samxon are good.

NOT totally wrong the Samxon GF and GL series are known to cause problems in some applications and just lately the GK series have started to wobble.

Use Search above for samxon threads and you will see.

Samxon is known cheap cheinese crap!

Re: are these bad caps?

They're not crap, some of their series are a bit poor, but for the most part their alright. Well, from my experience they seem ok.

They f**k up several of their series of caps, I really don't think that is ok.

I guess even Samsung made a singe TV or two, that lasted for more than 2 years. That still does not make Samsung a good brand

"They f**k up several of their series of caps, I really don't think that is ok." I might have just got lucky then, as I have never seen one fail.

"I guess even Samsung made a singe TV or two, that lasted for more than 2 years. That still does not make Samsung a good brand"
I agree with that, I have had too many shamsungs fail on me in the past. Unfortunately, I chucked them all out, and that was before I was aware of the cap problems, lol.

Ahh, what a shame. You could have saved a buck fixing them

UCC is in that boat too with KZG, KZJ, and TMZ.

In my experience, it's typically Samxon capacitors that are the cause of Samsung monitors becoming defective. For example, here is a Samsung Synmaster 2220WM with bad Samxon caps on the power supply board:

Re: are these bad caps?

if any board has bad design, caps can bloat no matter how good quality they are

Good point.
