I need help decoding a bad cap LG plasma tv (60pv450)

[Saraleigh]

Hi guys. I'm new to this & see the this community is awesome. U guys freely give advice over & over. So I want to thank u ahead of time.
My issue is a LG plasma tv (60pv450). I read enough to see that the cap on c802 was bad. I'm trying to decode this cap & im just not getting it. Can u help me. The cap reads FL 1.5 KHP 333H S K42, so far I've got out of this is
33000pf at 1.5kdv .

Any good clear pictures of the cap?

Re: I need help decoding a bad cap

It has the marking that I referenced in the Initial post

Re: I need help decoding a bad cap

Are you sure the cap is bad? it is usually the black square type that bulge that are bad.
This one from digikey would work 495-4767-nd or 399-12622-ND (2kv)

Re: I need help decoding a bad cap

I'm fairly sure it's bad. It appears to be bulging on the sides. However I didn't test it yet. Was trying to identify it first.
Thank u so much for the product code

Re: I need help decoding a bad cap

That green cap you posted looks ok. it looks original and not bulged, it was never square. I believe that cap that goes bad is on a different power supply board but same location.
Since you never mentioned what the problem is, I suspect there are other issues.
this is what the bad ones would look like

Re: I need help decoding a bad cap

I'd expect dry capacitors to immolate before seeing something like this... at least if I assume that's a polystyrene/polypropylene capacitor.

I imagine there's a story behind this capacitor, what kind was this really, and how did this happen?

Re: I need help decoding a bad cap

I have seen many polypropylene with same failure in lots of Samsung, look for CI818.

Re: I need help decoding a bad cap

Which model?

CI818 seems to point to many different inverter board capacitors... but how is this thing stressed to cause it to bloat like that -- or is it just a capacitor manufacturing QC problem?

Re: I need help decoding a bad cap

Many models, the cap that failed is used for coupling/DC blocking from the Bridge drive to the primary winding of the inverter transformer, or power transformer.

"but how is this thing stressed to cause it to bloat like that" I have no idea, it is needed to be taken apart and analyzed.

Re: I need help decoding a bad cap

Okay that one is a bit more voltage "stressed" - I saw another schematic when I searched for a Samsung CI818 that was a 0.01uF filter capacitor hooked up directly to an input of a LM393 op amp and was wondering how that could possibly be stressed...
