Hp vs17e 17" LCD Monitor, No Power, Will not Turn On

[ComputerGeek]

Hello, I have a Hp vs17e 17" LCD Monitor That Will not Turn On. I Pulled it apart and immediately found three caps that were oozing. I assumed that they were on the 5v Rail being 10v caps, plugged board in out of the case, and Pulled out my multimeter, turned out correct they measured 5.1v, however I got a surprise when I hit the power button the 5v rail drops to 0.75v. Anyway, I am almost sure that those caps are the only problem on the board, as I was able to get the power light to flicker dimly with only the board connected.

On to the Questions,

What Caps should I replace on the board? It's only a 17" monitor so I don't want to put too much money into it.

I think most of the caps in the list on this post are the same https://www.badcaps.net/forum/showthread.php?p=92533


As for the 3 Caps that are Leaking and two other that might be raised slightly what do you suggest for replacements?

2 Su'scon 1000uf 25v UK Series 105C Caps 13mm Round, Probably could go 15mm

3 CapXon 1000uf 10v KF Series 105C Caps 10mm Round I don't think it can go any bigger.


These Must be under 19mm High Might be able to fit a 20mm but it will be close to metal, Current Caps are both 16mm

Thanks!

Should Also, mention that none of the other caps are visibly bulged. Thanks!

The OEM for HP seems to have combined the main board (scaler), power supply and inverter onto one board, I suppose to save a few bucks.Your first step would be to replace those caps, yes. Panasonic FC/FM/FR is a favourite here ("good" to "best"). I would consider CapXon and Su'scon replace on sight parts.

So which ones should I replace? It only a 17" so I don't want to spend a lot on it as I said.

The bulging ones, and then only the rest if it still gives problems.

Are there any others that are more important than others that I should replace? Thanks!

they are not visibly bulged they still can be bad in ESR and in polarity example 1000m/fared --> can be only 200 m/f. the best move to make change them all. they are cheap anyway.

For the (2 Su'scon 1000uf 25v UK Series 105C Caps) I looked all over and finally found a datasheet [I attached the page] however the can size is not the same. How do I tell the specs? Also I can't find the Impedance.

These are the only Caps at digikey that are in stock and seem like suitable replacements.

These have a 7.5mm lead spacing instead of 5mm, but I think I could squeeze them in.

http://search.digikey.com/us/en/prod...0279-ND/266288

Looking for the Capxon datasheets now. Thanks!

Re: Hp vs17e 17" LCD Monitor, No Power, Will not Turn On

Acording to this datasheet () the Maximum Impedance is 0.076 and the Maximum Ripple Current 1040mA for the Can size.

Which one of these should I use? The Nichicon seems better?

Are any other Caps on the Board that get a lot of use that are more important than others, and more likely to fail, that I should replace? Thanks!

If anyone could answer the questions in my last posts I would be appreciate it. Thanks!

The Nichicon is good, I myself use PANASONIC FM series, I would also replace all the caps in the secondary side all at the same time.
Here is the service manual.

Re: Hp vs17e 17" LCD Monitor, No Power, Will not Turn On

How do I tell which ones are on the secondary side?

Re: Hp vs17e 17" LCD Monitor, No Power, Will not Turn On

See my suggestion.

See my suggestion.

Perfect! "You Da Man" A clear simple photo that I can follow!


I'll look those up and get a list on digikey. The only question I have curently is about the 2 Su'scon 1000uf 25v UK Series 105C Caps (Post 8) if someone could answer that i would be grateful.

Thanks!

You cannot go wromg with teh PANASONIC FM series for those two caps, I use FM series in all my repairs.

I would however all of the FM series are too high, even if I go up on the voltage. I guess I could put a piece of plastic on top so They don't touch the metal case, I might be able to fit them. However, they won't have any room at all.

I can't find the Specs on the 2 Su'scon 1000uf 25v UK Series 105C Caps either what should I do?

Re: Hp vs17e 17" LCD Monitor, No Power, Will not Turn On

Bump for a old thread, I have a bunch of Caps I am going to be ordering from digikey. So I want to get a list together for this. I also got another one of these in so I will have a double order of whatever caps I get. The Second one works Suprisingly even though it has the same date code.

Re: Hp vs17e 17" LCD Monitor, No Power, Will not Turn On

PANASONIC FR series may also have smaller body size available.

[ComputerGeek]

Re: Hp vs17e 17" LCD Monitor, No Power, Will not Turn On

OK I'll check on that.

I Also can't find the Specs on the 2 Su'scon 1000uf 25v UK Series 105C Caps either what should I do? What do you do if you can't find the Specs? Just replace them with a Low Esr Cap and assume it has to be better than the Su'scon Junk?

Yes, I will always trust the PANASONIC caps. I must have done close to a thousand monitors and TV combined now using nothing but PANASONIC caps.
