Okay so i self taught myself a lil about lcd tvs today and i go to fix a 37" tv i picked up. i find the bad cap, desolder it and then i couldnt find a 16v1000mf 105c cap anywhere but there is a 16v1500mf 105c cap on a motherboard i dont use anymore and was wondering if that would work just fine?

Re: LG Bad Cap Help

It could and probably would if its on the secondary side of the PSU, I have swapped caps on secondaries many times so far with great success. Although you should remember the rule about swapping caps with higher rated ones - never go more then 50%+ capacity and never go with smaller capacity then the original.

second side of the psu being furthur away from the pins that the power connector connect to?

Re: LG Bad Cap Help

I'm not a born-again expert (yet) but yes, generally farther away. You can usually look at the circuit and tell where you switch over from the high voltage to the low voltage. A rectifier is a good indication. If I'm wrong, someone please correct me. I've been out of this game for a long while, but the thread hadn't been answered and I wanted to try to help the guy out.

I wish it works fine. I know the trouble of doing this cause I've done it myself, unfortunately did not worked.
Good luck.

Re: LG Bad Cap Help

the capacitor actually costed me $1.39 with $7 in shipping and handling but because they screwed up and took so long to get it to me plus charge me $7 for s&h that wasn't supposed to be there i got a $25 coupon from them. And the capacitor is this. http://www.radioshack.com/product/in...uctId=12460839 im not sure if its has a lower esr or if its a normal cap.

Ughh... not really good. The capacitors Radioshack sells are not brand name, so you can't tell how good they are.

You should have asked for our advice and buy a good brand capacitor from this site or a reputable store from digikey.com or newark.com - about the same shipping fee and cheaper price.

What you have will obviously work for now, as your tv works, but it's quite possible it will have a small life.

Re: LG Bad Cap Help

and when it does ill just fix it again lol

Re: LG Bad Cap Help

Yeah, that's an OK strategy... just flip a coin now to see if it's gonna take down other (possibly harder to find) components with it or not, when it goes bad.

Digikey.com sells quality low ESR capacitors and their shipping prices are usually in the $2.75 USD ish range with deliverly in usually 2 to 3 days.

Badcaps.net also has a capacitor store.
