Look for lower ESR.
You are going up by 50%. That's a pretty big step.

KZE is -probably- good enough but, lacking actual data, if they have Panasonic FM or FR that would be better.
What series Capxon is it?

This is good if the numbers are right.

Re: Samsung 244T ...stuck in standby

well it seems I have no choice but to order from the states ..as neither RS, Farnell or Rapid stock All the caps... seems hard to believe they can't be bought in the UK but there you have it

It turns out the items can be ordered from the states via Digi-Key's UK site ..they assure me they have an arrangement with customs and delivery takes 3 days...they say I am liable for the VAT(import tax 20%) ..but are vague on how I pay this exactly ...I have heard of people being charged £30 for a £10 item and their package being held by customs until its paid...so I hope this doesn't turn into an expensive nightmare

digikey want £12/$19 dollars for delivery..so in total excluding vat and any other hidden charges the order will come to roughly £20/$31...the other option is ordering from the u.s. using Farnell but they want £16/$25 for delivery...but they are a bigger company and don't mention anything about VAT so maybe the import tax is included in the delivery costs

Re: Samsung 244T ...stuck in standby

thanks for the suggestion jet, but I tend to avoid ordering from the states as stuff can take weeks to get here ..and with xmas just round the corner maybe even longer ..as it says in the small print

International mail delivery varies from country to country. If you don't receive your shipment within 3 weeks, contact us for further direction.

it has something to do with clearing customs ..unless you spend a small fortune on postage there is no way to cut the time down ...I'm not sure this monitor has weeks left in it...unless I upgrade to a more powerful hairdryer

also those kits dont tend to include the 450v cap ...on the up side I just snagged a great pic of the powerboard from that ebay ad & the parts list seems to check out though only farads are mentioned and in what quantity ..no esr,ripple etc

[jetadm123]

Re: Samsung 244T ...stuck in standby

Maybe to avoid the minimum order that Farnell charges, have you considered ordering a cap repair kit through Ebay? The US seller below has sold many of these kits. Be sure to compare his parts list to yours.

Re: Samsung 244T ...stuck in standby

did a forum search for "244t" but couldn't find any decent pictures of the power board ..found a couple on google images but they are not much better than the one I used ..if someone has a link or can upload a decent pic of the power board for a 244T...I will label it for future ref
--------------------

here is my shopping list so far ..based on this Capxon datasheet and ordering from Farnell ...if someone could cast an eye and also offer suggestions where I'v run aground ...would be much obliged

1) #### for the 47uF@50v couldn't find a lower esr than the CApXon & for the 47uF 63v could not find a higher ripple & lower esr

2) Could not find datasheets for the last 2 on the list so went with a guesstimate ...the 450v is vertical to the board and where the pins meet the board there are 2 silver square feet ..but I'm thinking these are just normal through hole and not snap in?

3) For the first one I'v included the values for FR,FM,FC for comparison ..I decided to go with the FR where possible as the values seemed slightly better

No I can't see the values in that pic..... LOL

Re: Samsung 244T ...stuck in standby

Check actual voltage.
Also post pic showing locations so people can look for pics elsewhere that might give a clue.
I think there's quite a few pics of that board right here in this forum.

just to check..can you see my pics in post #19 of this thread? ..maybe I have to make them visible or something?

[PCBONEZ]

Re: Samsung 244T ...stuck in standby

Check actual voltage.
If either are over 10v that's where the 50v goes.

Re: Samsung 244T ...stuck in standby

wait tho ...that means our part lists are the same ..the only question is which way round the 2 caps go ...I could go ahead and order ...and then just check the caps when I remove them to put in the new ones

can someone confirm the above isn't nonsense ..I'v been staring at this all day and a little tired ..but want to get on and get them ordered

Re: Samsung 244T ...stuck in standby

could be ..its just a bit funny that if I swapped jonnies values around then his list would be the same as mine

me:

CS802 50v@10uF

jonnie:
CM809 50v@10uF
CS802 10v@100uF

You may have different revisions of the board.

Re: Samsung 244T ...stuck in standby

yep, Farnell have a £24 min order but free delivery ...RS don't seem to like dealing with the public ...their site requires a trade account to make an order..they have a shop in town but it's a trade counter so not sure if I can buy from them easily ..I could probably add a few more things to my Farnell order to make it up to £24 ...Rapid are ok but they want £7 delivery...I could spend that £7 at Farnell instead ..I will price out the suppliers when I know exactly the parts I need...

...and on that note I'v just noticed crazyjonny has different cap values from me

https://www.badcaps.net/forum/showpo...89&postcount=8 ...thread here ....I think one of us has got 2 values swapped by mistake

Re: Samsung 244T ...stuck in standby

You also have RS Components there I think.
.
Ordinarily you need to replace all the lytic caps on the power board except the large high voltage one.
.
The real problem is the quality of the caps and if some are gone already the rest probably aren't far behind.

Re: Samsung 244T ...stuck in standby

aha ..I just re-read your guide and noticed the ripple can be higher and the impedance lower ..I will order those pannies at your link and update the thread how I get on

great forum btw ...and thanks to everyone who replied ..very helpful

And Farnell want £20 minimum order value,before adding Vat ???

Re: Samsung 244T ...stuck in standby

Don't forget to replace them ALL. All means all, not just the bloated ones.

Re: Samsung 244T ...stuck in standby

they are:
size: 13x25
ripple: 2780
impedance: 0.019

When I give examples, I try to select caps that are widely available around the world. So if you choose Panasonic FM as my example, you would get (using "1000uf 35v fm" for search)

http://uk.farnell.com/panasonic/eeuf...=1000uf+35v+fm

12.5mmx 25 mm, 3190ma, 15 mOhm

Re: Samsung 244T ...stuck in standby

Im in the north of scotland ..& have found somewhere to deliver ...but the range of caps is a bit confusing and haven't been able to find exact values

the 3 swollen caps for eg are 3x 1000uf@35v

and from looking at what I think is the datasheet

they are:
size: 13x25
ripple: 2780
impedance: 0.019

have narrowed down some decent brands here ..but not matching the impedance and ripple

you can do your own search by value here

should i get caps with a voltage higher than 35v ..or just go with 35v?

[trebo]

Re: Samsung 244T ...stuck in standby

..Im just wondering about the heat thing ..as ordering components is expensive here and would like to get it right first time if possible

where are you by the way?, we may be able to tell you the best places to souce parts

also the big filter cap on its side rarely fails so its not often replaced, but in this model of monitor you might want to replace it after reading this,


https://www.badcaps.net/forum/showth...t=Samsung+244T

there are other threads on this monitor in the forum for you to read, they may intrest you and help you

[jayoung]

Re: Samsung 244T ...stuck in standby

that puts my mind more at ease that it's the caps.. should I use the same type of cap thats in there already ..black radials with stripe ..or is there a better type or brand to use

There are several threads on the forum about what good capacitors to buy, the following is one of them:
https://www.badcaps.net/forum/showthread.php?t=2280

retiredcaps explains one way of finding suitable replacements:
https://www.badcaps.net/forum/showpo...4&postcount=19

If you make a list of the capacitors on the board with the uF, V, diameter, height, and the part you think will work, someone on the forum can verify your results.
