Looking for help to determine what capacitors to get

[stw1911]

I have a Magnavox flat screen TV, Model# 37MF337B/37 that needs repair, and has some blown caps. Four are on the power supply, and three are on the mainboard. They are all CapXon caps, and I would like to replace them with much better quality ones. Three of them are CapXon GF 105 degree PF710 VENT 1000uf 35v, three are CapXon LZ 105 degree P711 VENT 1000uf 25v, and one is CapXon GF 105 degree P706 2200uf 25v. Links to Digi-Key, and or any other help would be greatly appreciated.

The Gf Series are 13x25 and the LZ Series are 10x20

CapXon GF 1000uf 35v 13x25 2780ma 0.019ohms
CapXon GF 2200uf 25v 13x35 3420ma 0.018ohms
CapXon LZ 1000uf 25v 10x20 2180ma 0.016ohms

i'll look at some better company's

panasonic FR
for the LZ replacement, use the 25mm tall version.

so:
CapXon GF 1000uf 35v 13x25 2780ma 0.019ohms > FR 1000uf 35v 12.5x20 2600ma 0.018ohms
CapXon GF 2200uf 25v 13x35 3420ma 0.018ohms > FR 2200uf 25v 12.5x30 3630ma 0.013ohms
CapXon LZ 1000uf 25v 10x20 2180ma 0.016ohms > FR 1000uf 25v 10x25 2470ma 0.018ohms

Re: Looking for help to determine what capacitors to get

Thanks for the help. One more question though. How do the differences in ohms and ma affect the performance, as in higher numbers better, or vice versa?

Re: Looking for help to determine what capacitors to get

higher ma is better, lower ohms is better.
but in the case of ohms - not too much lower.

also, those FR are rated for 10,000 hours minimum life.
the originals are probably only 2000

Thank you so much for the information. You have been a very big help. Hopefully these are the only things wrong with the TV, and I will have myself a nice 37 inch flat screen for only around $15.00 and a little bit of my time. Thanks again for the help.
