Magnavox lc32sl1

I have this TV that takes a while to turn on, I found three 10V 1000uF caps that are bulged and leaking. I have available a couple of TV parts that have two 16V 1000uF and a 25V 1000uF so my question to you guys is, can I use the combination of 16V and 25V caps in place of the 10V caps?

Re: Magnavox lc32sl1

The main thing is that it has to be low ESR type cap (such as PANASONIC FM/FR/FC series) since it is used in the hi frequency power supply. You can use what you have right now just to try it out to see if the TV will function then you can order the right type, general cap will not last in switching power supply.
That 10V 1000uF is for the 5V power supply for running the main board.

Re: Magnavox lc32sl1

BUDM do you consider Panasonic caps the best? My second question to you is, I have ordered low impedance Nichicon caps from mouser, I have been told low impedance = low esr, yet I can find those same caps at digikey and they will state that the caps are regular usage caps. So is low esr the same as low impedance?

Re: Magnavox lc32sl1

Capacitor ESR is not the same as Impedance. Impedance is more complex measurement of the caps.
You can learn more by Google "what is impedance rating of the capacitor"
I.E.



I cannot say which brands are the best as far as Japanese made caps are, but I have very good records with PANASONIC caps. I am sure the NCHICON low impedance will be fine. You can compare the spec of the PANASONIC and the NICHICON (depends on the series).

Re: Magnavox lc32sl1

Does the diameter and height matter? If I have a cap that is 10mm X 20mm can I replace it with a cap that is 12.5mm X 20mm? Or a 10mm X 18mm replaced with a 10mm X 16mm cap?

"If it fits, I sits."
Cap diameter/size isn't important other than getting it to fit.

Re: Magnavox lc32sl1

Wonderful, although I keep looking at mouser and digikey for low esr caps and every cap either says general purpose or low impedance. Nowhere does it say low esr.

Re: Magnavox lc32sl1

Yeah, I have seen that often. If unsure, look at the datasheet for low esr or low impedence.

Re: Magnavox lc32sl1

Give us a link to one that you are looking at - there is usually another column for ESR but its not always populated - try the data sheet

Re: Magnavox lc32sl1

HZ is "too" good. They are designed for computer motherboards; a power supply may not work well with them. The other two are good.

Re: Magnavox lc32sl1

Oops, the HZ is what I ordered. Crap!

[ztu165]

Re: Magnavox lc32sl1

What are the chances the HZ caps might still work? Or am I completely screwed?

Re: Magnavox lc32sl1

It will probably work. The problem is, some power supplies may not work with it, so I suggest FM/FR/FC as they work with virtually every power supply.
