Re: need suggestions replacing large capacitor



an air conditioner compressor unit, and they charge me about $40 for each replacement

its quite costly

its been at least 3 times now theyve been replaced unless.... they are taking me for a ride....

Re: need suggestions replacing large capacitor

Actually I was more hoping for a quality replacement because we've replaced this MANY times and they just keep breaking

Unlike usual capacitors on psu im not sure what to search for

Any idea what to replace (attachment) with?...

Re: Please suggest capacitor replacement

budm: I think so, I did go ahead with what you suggested.

Thanks!

From my ASUS RT-N16 router:

HERMEI LZ
1x 680uF/16V - 10x13mm, 1400mA, 0.026ohm @ 25c / 0.078ohm @ -10c

Long ago someone suggested some rules when buying a replacement.
[CODE]#new vs old
~~~~~~~~
capacitance uF =
voltage V >=
ripple mA >=
ESR/impedience ohm <=
height (d x l) mm <=
spacing mm =[/CODE]

I've been following that rule all along but this time.. I can't find anything within the configuration.

I will need to purchase from:

Re: Please help me decide replacement capacitor

LG L226WTQ-PF (MY BAD SOLDER WORK):


Backlight is on but no display.
Pressing on menu button doesn't show anything. Actually none of the buttons do a thing -- zoom, source, menu, etc etc.
Turning on and off does show the LG logo middle of the screen. Very clear.
Also displays source at top right corner. Very clear....

Re: Please help me decide replacement capacitor

There are 2 monitors I'm unable to repair:

LG L226WTQ-PF:
capacitors replaced
bad soldering work, pictures to come soon. waiting for camera
light tubes go on and off normally when monitor is on/off, however, no picture can be seen

Samsung 931BW:
nothing's changed.
capacitors not even bulging, looks good.
picture displays a split second then disappears. selecting source causes it to display for a second then disappears again.
found someone else with this issue. this...

Re: Please help me decide replacement capacitor

2 monitors don't seem to be capacitor issue! Hmm.. they display for just a split second then picture disappears. By selecting the source from the panel, it displays again for a split second then disappears.

Re: Please help me decide replacement capacitor

I've already purchased and received the following (for various monitor repairs):

EEUFR1E102 CAPACITOR, RADIAL, 25V, 1000UF EEUFR1E102
EEUFR1V681 CAPACITOR, RADIAL, 35V, 680UF, 20% EEUFR1V681
EEUFM1A102 CAPACITOR, RADIAL, 10V, 1000UF EEUFM1A102
EEUFR1E821 CAP, ALU ELECT, 820UF, 25V, CAN EEUFR1E821

They are all panasonic.

I've fixed a Samsung 931BW, and a AOC 2219VG.

I just did a LG-L226WTQ-PF. The screen power LED now goes standby/lights up normally when the PC...

Re: Please help me decide replacement capacitor

Hm, perhaps its my misunderstanding.. but would you mind telling me when replacing PSU / monitor PSU caps, what are the things to look at then for a more prolonged lifespan? Is it to check those 1000h@105c? I've went ahead and purchased 10,000 hours @ 105c with lower ESR, higher ripple... Please correct my mistakes

Re: Please help me decide replacement capacitor

choice 1: 0.019ohm 2180mA PANASONIC
choice 2: 0.052ohm 1220mA PANASONIC
choice 3: 0.023ohm 1820mA PANASONIC

Re: Please help me decide replacement capacitor

monitor

replacement caps: panasonic

Some people on IRC are telling me choice1/3 is better.

ORIGINAL CAPACITOR:
EPCOS 1000uF 16v 10x20 0.054ohm 1100mA

REPLACEMENT:
choice 1: 0.019ohm 2180mA
choice 2: 0.052ohm 1220mA
choice 3: 0.023ohm 1820mA

which to pick?

Re: Replacing LCD CapXon Caps

I'm going to purchase a new solder wick. (2mm seems a bit small and difficult..)

My eyes are on

3.9mm wide oxygen free copper
5.3mm wide rosin oxygen free copper

which would you choose? I feel 5.3mm is rather too wide... but I'm not sure if being extra wide causes for-now-unforeseen problems.

Maybe i'll buy some liquid flux.. not very sure if that flux pen works at all haha... or im using it wrong. Any tips on liquid flux? Also, how do i clean off flux, alcohol?

Would like to ask...

Re: Replacing LCD CapXon Caps

If you're interested to know, I've successfully revived the monitor with all the recommended items you provided, not to mention with bad solder work. I guess experience is needed. That braid was rather thin though. Didn't quite like that. Had difficulty getting the solder to stick to the braid.

OK, many thanks for your replies.

BTW: for desoldering, is a 60/40 better? I notice adding some solder helps in desoldering.. then i couldnt help but wonder if a 60/40 would work better for that.

Re: Replacing LCD CapXon Caps

It just occurred to me.. will I need decent tweezers to hold caps? Searching element14.. there's a whole range of these goods...

Re: Replacing LCD CapXon Caps

Okay.. you're right I haven't watched this. As funny as it may seem, I'll be getting my gf to watch it as she will be doing the soldering. My hand shakes as hell so I'm probably no good at this. I saved the links though, I thought I should watch them after purchasing. Incorrect assumption.

Now I realize, everything you say is very absolute.

Proceeding with purchase now.. a very big thanks for all the help and recommendations.
