Lg 226 wtq

[akuthia]

Hey there bad cappers.Here's the back panel Of my monitor. As you can see, it's about 8 years old. Earlier this week it seems like my monitor started to die. I want to see if you can confirm my suspicions that it's capacitors (and maybe provide some assistance on replacing them)

The symptoms started after doing some PC upgrades, but i've since narrowed it down to a monitor issue only. At first, when i'd wake up in the morning, I'd go to wake up the monitor, and the monitor would respond, but not actually show an image for ~30 seconds. The power light was blue (indicating it was powered on, and connected to the PC), and there was no "check connection" style message. In use, there was no issue with the monitor. Fiddling with power and DVI cable would eventually turn it on. This morning, I go to do the same, and there's no response, until i get what seemed like a solid white flash a couple of times.

I haven't been able to actually open up the panel yet. Following these instructions, I have the screws out, however I'm unable to pry the front bezel off, even using a flathead screwdriver as leverage.

So, the first question is, does this sound liek a cap issue to you, and secondly, are there any other hints to getting the frame off this monitor to get to the inside?

Re: Lg 226 wtq

it might be bad caps
seeing the board would tell

he may have had that trim off on that video which might be why it came off easy
some are a real pain especially at the corners.
try taking an old credit card and sharpen an edge so that it is like a wood chisel . you can do this by rubbing it on a concrete floor or using a nail file. Then work that between the front frame and rear case starting in the middles and while rocking the front away from the lcd screen.

Re: Lg 226 wtq

i'll second that,
getting plastics apart is easy if you use something worthless like a bank or satellite-viewing card.

You lift the front bezel up.

Re: Lg 226 wtq

ok so this is where I'm at, however, i'm hearing what sounds more like a "tearing" than a popping sound, and it's scaring me to hades and back. Is that the right sound? or am i screwing something up?

DO NOT DO IT THAT WAY
Especially with a knife, you will crack the screen and be DONE IN !!
It may be double faced tape releasing
go from the outside between the two plastics

I just looked at one picture and cringed-- SERIOUSLY !!! A SCREWDRIVER !!!
you do realize that most people looking for help have not done this as often as you have and will probably crack or scratch their screen when they slip !!

Maybe if you wrapped it with tape first

Re: Lg 226 wtq

ok, so i got some help popping the front off. Here's what i've got on the inside and PSU side Now on the PSU side, all of them look slightly bulged, and a couple of them are obviously cracked, but do those seem to match the symptoms, since they're on the PSU side? Primarily being that it was definitely getting power, but not actually displaying an image?

Re: Lg 226 wtq

eeks
yep it needs caps on the power board
also replace that one small one while you are at it

The small one meaning the leaning tower of piza over there by itself?

[bammbammfran]

Re: Lg 226 wtq

I do not notice it leaning too bad
it is C10x (can't read the rlast number)
between the yellow square hipot and the aluminum heatsink on the power supply

I do see a leaning one on the vga dvi board-- but that boards caps look ok

[akuthia]

Re: Lg 226 wtq

ok I see the one you're talking about now. Trying to source them now. One radioshack only had the leaning one, so that's not a concern that it's bent over like that?

Edit: so far radio shack is saying they've only got 1000uf in 35 & 50 v which if i'm not mistaken will likely bring about the end of the univere if i try to use them, correct?

will take 2-3 days to get to you but prices and product will be better than radioshack

leaning one is ok since it is going perpendicular to the pins. you can right it if you like

Re: Lg 226 wtq

Th screw drive is to show that you will lift that section up while I am taking the picture, you lift it up with your finger. I only have two hands. When you work long enough you will learn what not to do. Wooden stick from ice cream works great and you have to take your time and do not rush.
Caps: I use PANASONIC FM/FR/FC series. They have to be low ESR type for switching power supply.
I.E. Just match the dimension, voltage (higher is OK), Capacitance (a little higher 20~30% is OK)

Re: Lg 226 wtq

is there somewhere i should be looking to determine the exact size of these? the only thing i see printed on them are the uF rating, and the volts

[budm]

Re: Lg 226 wtq

Take good notes where each cap is removed from, then use the ruler to measure the Dia, and length (in mm is preferred) to match with the replacement.

what are the uf and voltage rating of each and how many of each
I'll try to get your the models at digikey if you want to go that route

might be a 1000x25 or 680x25
those are 10mm diameter and maybe 20mm tall

the small one maybe a 47 or 22 x 25 or 50
probably 6.3mm x 12mm

For the big ones, it's 1000uF, 25v and this is is the only match (actually, i tihnk there were 2, but they seemed identical to me, on the chart,the other just appears to be an out of stock bulk.

The small one is 33uF, 50 v, of which digi key is giving me no matches for.

Re: Lg 226 wtq

all 5 of the large ones are 1000 ?
link to digikey that you posted didn't work (seen this before)

1000 x 25
P15349CT-ND
22mm tall (make sure the 22 mm tall is not higher than the heatsink)

33 x 50
493-1895-ND

LOOKS LIKE A COUPLE ARE 1000 x 16v
P12366-ND

Im about to see if i can track down the soldering iron and pull them out now and will verify
