LCD TV with a bulging cap in power supply

[eyespider]

Hi my sister gave me a TV. It's acoustic solutions lcd26762hdf

yep I've never heard of that brand neither.

Well it turns itself off after about 1 min.

I took the back off and there is a capacitor on the power supply board which is bulging.

I would like to replace this with a superior one.

I look at the cap in question and it says :

SAMXON 1000u F16v
105ᵒ C6
W9A
GF(M)

Replace it with Low esr of the same value, also replace any other Samxon Gf brand capacitor.

Re: LCD TV with a bulging cap in power supply

Hi Is Samxon a rubbish brand?
and which one is the ESR rating

[budm]

Re: LCD TV with a bulging cap in power supply

GF series are LOW ESR type, 105c.

I would replace them with PANSONIC LOW ESR, 105c FM or FR series.

Re: LCD TV with a bulging cap in power supply

esr is not printed on it, you need the GF series datasheet.

however, dont concern yourself with it, just use panasonic FR series.
be carefull to get the correct diameter and height or the tv may not go back together

and dont use ebay - use RS or Farnell

Re: LCD TV with a bulging cap in power supply

nice. thanks for help guys. Is it ok just to replace this Samxon with the panasonic and leave the other Samxon caps?

Re: LCD TV with a bulging cap in power supply

If you need practice taking it apart, replace them one at a time every couple of months.


Not that I'm a smart-aleck or anything. I usually replace all questionable parts while I'm there. If I have to come back, so be it, but I'm going to try to not let that happen. Personally I don't trust any but Panasonic, Nichicon, or Cornell Dubillier, maybe Rubycon.

^This, if one cap failed the others have been exposed to the same stresses (heat, ripple, etc.) for the same amount of time, and likely aren't far behind (especially those that are the same brand and series, meaning they are engineered to the same specs.).

ok cheers guys
will let you know how I get on

Re: LCD TV with a bulging cap in power supply

I've been working on a similar situation with a Gateway monitor suffering with the Great Capacitor Plague. I'd suggest replacing them all so the full compliment of electrolytic caps are the same age. During old capacitor removal, one shortcut I've learned is to grasp the capacitor with a pair of gas pliers as you wiggle and pull them off the board. Once you physically pull them off, all that remains are the leads with the rectangular terminals that were formerly inside the cap. Then with the cap body removed, there is less heat sinking when de-soldering the leads making the job faster and easier. I used to use the a cumbersome "solder sucker" tool that didn't actually work and also the copper braid "solder wick". The solder wick works but limits your visibility and usually ends up with burnt fingers. In place of this procedure, I now leave all the old left over solder on the circuit pad and use a straight pin from the wife's sewing, pushing it through the board while heating the circuit pad. This facilitates lead space for placing the new caps on the board and then soldering with just a tad of new solder. As for finding replacement caps, I always use Mouser Electronics because their listing are extremely extensive and complete. On the site, just search for "Electrolytic Capacitors, Leaded". My favorite caps are Panasonic with a balance between quality and price. Here, you can select Regular or Low ESR types among others.

Re: LCD TV with a bulging cap in power supply

just checked one of my spares the gold strip is minus -

Re: LCD TV with a bulging cap in power supply

oh boll0cks I've got to desolder it then. Good job i didn't put it back in the TV lol

[eyespider]

Re: LCD TV with a bulging cap in power supply

Get in!!!!
I've fixed it, it's working perfect. Many thanks to everyone who helped me out.

[vinceroger69]

Re: LCD TV with a bulging cap in power supply

Thanks for posting the update and glad the capacitor fix worked not sure if you have replaced them all on the power supply but its always best too,although i usually leave the main large filter capacitor on the hot side of the psu, as thats usually fine.

Re: LCD TV with a bulging cap in power supply

confession....I just replaced the bulging one as I am inexperienced soldering. As this has given me confidence I will now do the otheres.

Re: LCD TV with a bulging cap in power supply

btw, "acoustic solutions" is a brand name of Richer Sounds afaik.

Re: LCD TV with a bulging cap in power supply

I had the 32 inch version of this set which had a capactior fault on the inverter circuit once repaired the picture quality wasnt the best so not sure what panel these use.

It (was) an Argos brand, a sort of higher-end version of Bush/Alba.

I don't think R.S. need the shit that was branded Acoustic Solutions. They tend to sell higher class stuff (or at least until Toshiba, Sharp and Panny started rebranding Vestel shit!)
