LG60PC45 capacitors

[habanerocat]

Hi,

I an trying to repair one of these boards with bad caps. I foolishly removed all the bad caps, thinking they were all the same value, 7 by 3300uF 10V. However then I noticed one was 680uF 50V.

Can anybody tell me which one is 680uF please?
I can't find a circuit diagram anywhere for this board, EAX31466601/5.

Would the odd one being 50V help me in any way?

Please help and thanks.

Lol I did one of these luckily for you a video too will upload it as I stated the positions of the caps in it.

That's great!

But I don't understand, upload it to where?

Thanks.

By the process of elimination and some guess work I replaced C222 with the 680uF and all seems to be working ok now.

Might help somebody else out.

It's a BIG TV.........

You can double check by measuring voltages at caps against voltage rating on them.

hi .i do the same wrong way,when im just find the bad caps , and i just desolder all of them,but when i check it , one of them it was different,and i have no idea,where come from.....
i do find it. it was on the "small PS board" position is c202
i changed all caps , and the tv is go back to live.

but after 2 days continued to use it,without switch on , my tv is just go to standby.
im just realized,the two fans is newer turning on,so maybe this tv just overheated,again. but,i can't se any bad caps.
when i try to switch on the tv, i hear two click noise(from relays) and after 6 green light flashing,just back to standby.
if i want to switch on again,10 or 11 green light flash and back to solid red without relay clicks.

just a short update.
i find the problem,the two small fans is not working,one of capacitor is just exploded.(c237) .so i decided to take the long fan from my another LG 50" tv , and install into big one.
i find the "Proper" place for the "big one" , im just remove the old fans and put the "new" on place.and i make a thermal controller and jobs done ! My tv is back to life ! I will share some pictures today,maybe is helpful for someone.sorry about my poor english.

Good luck !
