244t trouble finding caps

[lsbnrgbrn]

Hello, I've had my Samsung 244T open for some time and have been reading the help guides and 244t threads but am unsure how to move forward. The ESR is not provided for any of my caps so I don't understand how to select appropriate replacements.

Much appreciation for any help getting started, in Canada Ont

Re: 244t trouble finding caps

Others with the same monitor have posted their cap's details of which differ from my own.
Could I just use the caps they have chosen, even though they are somewhat differnt?

Also, I wouldn't mind ordering from Farnell so that I could get a couple raspberryPis

Re: 244t trouble finding caps

Here is a list of good capacitors to use don't use Capxon or Samxon

read this section of badcaps https://www.badcaps.net/forum/showthread.php?t=388

On the FAQ we have the following list of good low esr caps to use. I would appreciate assistance in updating this list. If everyone can assist in advising series to add, that would be helpful.

Nichicon - PM, PW, HV, HD, HC, HE, HM, HN HZ (we do not recommend using HM or HN series presently due to early fails of those series.)

Nippon Chemicon - NRSZ, NRSX, NRSY, NRSJ, NRSG

NRSX is probably the best

United Chemi-con - KZE, KZH KMG, KY

KZE are used on many boards recently.

Panasonic - FC, FM, FK, FA FJ

Panasonic FC are highly available and recommended.

Rubycon - MBZ, MCZ, ZL, ZLG ZLH, ZA, YXH, YXG

Re: 244t trouble finding caps

Yes, I've read all of that and then some.
My problem is that I'm unsure how best to choose replacements without the ESR of my caps listed.

Should I just use my ripple and an ESR similar to someone with the same monitor?

Or,

Since there were several revisions to the powerboard of my monitor, and there are kits available that likely have different ripple and/or esr to that of my own,
could I even use a kit or someone else's caps of the same monitor?

Re: 244t trouble finding caps

While low ESR is important for the power supply and inverter circuits in an LCD monitor, in my opinion, it's not SO critical that you need to sweat the specs too much.

I use Panasonic FM, FC and FR series in all of my monitor repairs. There is some difference in ESR and ripple ratings between the 3, but they're all more than good enough, and certainly better than the caps you're replacing, again in my opinion, some others may differ with .
I'm doing a motherboard for a dual Xeon computer, and for THAT repair I AM sweating the specs and getting caps that match or exceed the originals, but for monitors and LCD tvs, I just use Panasonics.

If you have enough other stuff to get to justify the $8.00 shipping, Digikey.ca is a great source.

Re: 244t trouble finding caps

That are what I used (FM/FC/FR) for ALL my repair.
The bag is full now after almost two years, fixed over 1000 TVs/Monitors/Power supplies.

"We" (I) certainly do, the problem with the HM and HN series was in 2001 to 2003, and has LONG since been fixed, they are now as reliable as the rest of Nichicon's series. I would also add VZ, they're a 105 degree version of VR, and just under PW in ripple rating. They make a great replacement for all general purose 85 degree caps.

Nippon Chemicon - NRSZ, NRSX, NRSY, NRSJ, NRSG

NRSX is probably the best

United Chemi-con - KZE, KZH KMG, KY

I would add KYA which is a downsized version of KY, and KZM which is a better KZH (lower ESR, higher ripple, longer life).

KZE are used on many boards recently.

Panasonic - FC, FM, FK, FA FJ

Panasonic FC are highly available and recommended.

Add FR and FL.

Unfortunately FJ and FL are only available to OEMs, so impossible to find except as surplus on ebay, and we all know not to buy from ebay . . . right?

Rubycon - MBZ, MCZ, ZL, ZLG ZLH, ZA, YXH, YXG

Add MFZ, but again only for OEMs (or maybe just Microsoft), again, only available on ebay.

Some unscientific stats:

I have not had any of my repairs come back so far.
I thought I had a repeat LG monitor, but turns out the user had 2 identical ones.

Just spoke with my very first monitor "customer" and his Dell E196F that I repaired in Feb of 2010 is still going strong. Used FMs in that one.
And a Xerox multifunction printer I did in August 2010 is still faxing copying and printing today. Again FMs.

Re: 244t trouble finding caps

Okay, I think I'm getting somewhere..
Should I be using a conversion chart for Capxon Km or Gl / Samxon Km series?
This is what I have so far. Will they be alright?

Thanks everyone, my monitor is now working.
Caps I used were:

UPW1H470MED 47uf50v
25YXG1000MEFC12.5X20 1000uf25v
