Another Westinghouse 19" monitor issue

[ATXjoe]

I think I have a bad capacitor on the power board, but I'm not 100% sure. I took photos of the board and of the capacitor in question. Looks to be a bulge in the top of the cap.

Any ideas on how much it would cost to have that cap replaced? I can't solder to save my life..

capacitor is a capxon 2200 microF 10v

Welcome to Badcaps.Net

I suggest that you get the data for all the caps (except the bi one) and post the data so replacement for all of them can be suggested, as it would be wise to recap entirely. The cost is small, but you need to do it yourself.
What model of the Westinghouse 19" do you have?
Also, what symptoms has the unit?

Re: Another Westinghouse 19" monitor issue

Hey eguevarae,
I have a Westinghouse SK-19H210S. It's classified by W as a LCD TV on their site.

My experience with electronics is limited to watching my buddy tinker and two labs in college. Of course I never soldered as we used those breadboards for all our projects.

Not sure which the bi caps are, but all the caps with the cylindrical form and defined (-) on them are:

All CapXon Capacitors
One 100uF 400V
One 2200uF 10V
Two 1000uF 25V
One 1000uF 10V
Two 220uF 25V
One 47uF 50V
One 22uF 50V

Dunno if I have the skills to recap entirely, but I can likely handle the one that is blown as it's on the outer edge of the board and not very cramped.

You forgot the series. In the second picture I see that the CapXon is a KF series. Make sure all are KF or post the series of all if they are different. Think of CapXon as the brand and the KF series identifier as a model. We need the complete info to suggest replacements (well, PCBONEZ needs it....).
And again, it would be wise to recap all of them at once. Not counting the big one (the first on your list) there are 9 caps in the list. If one blew, all of the others will almost for sure give problems (maybe they are bad already, but with no indication you'll not know without an ESR meter). Just imagine opening your LCD 8 times more instead of doing it just this time ....

And you still have to post the symptoms.

And the symptoms?

Re: Another Westinghouse 19" monitor issue

Unit will not power on at all.

Did you check the fuse at the AC input (black box at upper left portion of 1st pic)?
If AC is getting in, have you measured the voltage reaching the caps?

Re: Another Westinghouse 19" monitor issue

I didn't. Was kinda scared to plug in the power board with the blown caps. If it's ok to do then I'll check. I have a multimeter. Gonna wait til my friend comes over though in case I electrocute myself. At least then I'll have someone to hide the porn from my family so that they won't find it when they are going through my estate! hahahah

And don't worry. It was working (or trying to) that way.

Re: Another Westinghouse 19" monitor issue

any idea which online retailer is the best place to buy these capacitors?
thanks

I prefer Digi-Key. Their low-cost shipping option is USPS first class mail. For small orders it's as fast as Priority Mail at 1/3 the cost.

I second that. Mouser has a higher shipping rate (not that much, but if you are ordering just for this unit, it really is not worth it).

Re: Another Westinghouse 19" monitor issue

Hey folks.. thanks to everyone who helped me. Two weeks and 50 bones later, my $250 tv works. I'm excited that this was something that I could prevent from going in the garbage and repair. So many cheaply made items are "disposable" and not cost effective to fix. Thanks again!!!

Maybe cost effective to fix, but not to pay for them to get fixed.
And congrats on your now working unit.

Re: Another Westinghouse 19" monitor issue

So I have the same monitor and also the same issue (bulging caps, won't power on).

I also have all of the same capacitors except for 2.

All CapXon Capacitors
One KM 100uF 400V
One KF 2200uF 10V
Two KF 1000uF 25V
One KF 1000uF 10V
Two GL 470uF 25V (these are different than listed above)
One GL 47uF 50V
One GL 22uF 50V

I was hoping someone could tell me what caps I can replace these with.

Also, if the OP had any other issues I might expect other than replacing the caps it would be good to know since our situations are almost identical.

Re: Another Westinghouse 19" monitor issue

I usually use Panasonic FCs in LCD inverters and power supplies.

Digikey has them.

This isn't the VRM of a mobo here where ESR is critical any good brand of low ESR caps will do.

Change the caps (400v one isn't really necessary. Leave it alone for now) and bring the monitor to life. If green power led shines in all it's glory and no image, we can mess with the inverter side.

Re: Another Westinghouse 19" monitor issue

Alright, here is the list of the replacement caps. Let me know if it's alright.

1000uf 10v: http://search.digikey.com/scripts/Dk...name=P10225-ND


1000uf 25v X 2 : http://search.digikey.com/scripts/Dk...name=P11223-ND

470uf 25v X 2: http://search.digikey.com/scripts/Dk...name=P10274-ND

27uf 50v : http://search.digikey.com/scripts/Dk...name=P10318-ND

47uf 50v : http://search.digikey.com/scripts/Dk...name=P10321-ND

2200uf 10v : http://search.digikey.com/scripts/Dk...name=P10230-ND


Also, just curious, why do I not need to replace the 400v? It doesn't seem bad but is there less of a chance it will go bad compared to the others?

Exactly. Only a power surge might damage it more often than not. They rarely fail (60+ units so far and I've not seen one dead or heard about one around here).
As for the list, one of our seniors will confirm it in no time.
