Vizio LP2626/VMM26-F20I

Re: Vizio LP2626/VMM26-F20I (after thoughts)

I had a similar situation, in my case however, c504 was clearly fried. (c504 is a 12pF, 3000 volt ceramic disc capacitor.)

This monitor was not made to come apart. Don't forget to take out the deep screws. After the screws are out, it's going to take some cautious brute force prying with flat blade screwdrivers (it's good to have several). Start at the bottom speaker grill where the flat spots are and work your way all around. After that, it's downhill.

Thanks for the above and good luck anyone trying to do this.

where was the best place to buy 2 of the 12pf 3kv caps?

Re: Vizio LP2626/VMM26-F20I

I replaced both 12pf 3kv caps inline with the ccfl and this did fix my monitor. thanks to all for the input on this post. BTW i have 18 12pf 3kv caps available if anyone should need any.

Did you test those ballast caps to see if the value has changed or it has leakage resistance? They usually fried with brown marking on the body. In your pictures, they look OK. I get my from MOUSER.

I just had mine die and have one black cap if i could buy a few just in case. let me know asap! thanks

Sportsman99,
reading this thread helps... however, someone like me.... well I know I am having the same issues and not sure what all these caps you guys are talking about.... I'd just like to buy the same parts you bought and hope it works... can you assist?

Re: Vizio LP2626/VMM26-F20I

@IRIEBLUES you will probably have to pm sportsman99 if you want to buy some of his caps

These caps circled in red, they are high voltage capacitors, see if any of them look brown (they are normally blue).

Hi guys - brand new - been reading and searching

my question is are the caps at 503 and 504 the same and is that also true on 517 and 519

my 504 is crispy!
my 503 reads N3 3KV SEC
my 517 reads N3 3KV SEC
my 519 reads 12J 3KV JNC

my thought was 504 might be the 12J 3KV JNC and maybe since 519 looks a little "dark" I would replace both 504 and 519

lastly is there an "alternative" cap that will not burn up - this thing was a PITA to open and I would rather not repeat in 6 months

THANK YOU for your inputs!!!

504 is the same as 519, they are symetrical.
I use TDK or MURATA, VISHAY from Digikey or Mouser. Just type in 3pf 3000V (or 6300V) in the search box
3pf 3000V, this will be hard to get.
12pf 3000v.
You can use 6300V instead, they will be larger.

Re: Vizio LP2626/VMM26-F20I

Thanks
so the link shows all caps removed - were they all replaced with the same P/N (12pf 3KV)

I am really electrically challenged so I thank you in advance for "dumbing it down" for me

Re: Vizio LP2626/VMM26-F20I

I repalce them with what they should be, two are 3pf, two are 12pf. I replaced tham as a set. So make sure you mark each location to make sure you install the right value at the right location.

Re: Vizio LP2626/VMM26-F20I

Thanks so much for the info and reply - I will report back my findings to bring a close to my end of the thread - planning to replace ALL 4 with same as factory

Re: Vizio LP2626/VMM26-F20I

WOOOHOOOO!!

Thank You - the monitor works perfectly - We bought some caps off ebay out of Canada for about $4 took about a week to arrive, about 5 minutes to install, tested - worked, put it all back together and I have one really happy boy! that is a very nice monitor!!!

Thought I would close out my end - so many newb's never come back and thank forum regulars -

as for what we did (guess that is important too) I replaced cap c517 and c519 with same size 12pf 3kv caps )only one was "burned"

I would like to add - the "ribbon" connector on the power board does NOT unplug!!! - if you want it to be removed you have to unplug it from the other end which required removing the other metal box, pcb and a few wires - then unplug the cable to the power board - use some sort of a marker to mark the placement of the box before removing so it will align with the back when re-installed (its just "taped" in place)

Anyhow - hope to use this forum again and thanks!

Re: Vizio LP2626/VMM26-F20I

SO i bought another monitor and replaced the 12pf caps the monitor comes on then off again after 3 seconds. i read resistor r525 and and it reads .9 Meg, can anyone tell me if this is a 1.5 meg resistor it is hard for me to read the color bands i would say it is brown/green/green. i did not have the 3pf caps but will get a couple of them but i wanted to replace resistors at the same time. Since they did not seem to read what they should.
i did see the pictures posted to this forum, awesome pictures i might add, still unsure of the resistor values.

Re: Vizio LP2626/VMM26-F20I

Does it read the same as R508? Did you test it off the board and your are not touching the meter probes with your hand?

[sportsman99]

Re: Vizio LP2626/VMM26-F20I

yes i did read them out of the board and it did read the same as 508. they looked somewhat dark in color but that could have been manufacturing. i read them with a analog meter and a digital meter (same results per say). with pg clips so as not to induce resistance from me. i have been able to keep this monitor up, but after a power cycle it is pot luck weather it comes up or not.. IF anyone has the 3pf caps for sale i could take 4 of them. i replaced the 12pf caps and have extras. i do have another vmm26 monitor i could pull the power supply on and read those resistors.. if any one has additional info thanks for the help.

[sportsman99]

Re: Vizio LP2626/VMM26-F20I

Well i decided to pull the power supply out of my working LP2626 monitor and i really like the way they stamped the resistor 508 and 525 it is a 1.5M resistor.

Re: Vizio LP2626/VMM26-F20I

That is correct. I just looked at my board last night.

Re: Vizio LP2626/VMM26-F20I

Just registered so I could see the pictures—thank you for these posts; gave me the extra oompf to go the rest of the way, dismantling (this monitor is the most insane thing I've had to get into! and I thought laptop screens were annoying...). One of the 12J 3KV (C504) was horribly disfigured. Interesting that it seems to be that one in particular across the board...?
