Re: Yuyang YP2632T: oil from cap ?

Ok.
I have removed some suspect caps and then put back them again (the same !).
I have replaced a Samxon 2200uF 10V (this seems to be a very problematic one) with a Daewoo equivalent one (I guess).

Than i put back PSU in the tv and now the lcd power on very well !!
But only one time !!
On the next times... the 5VSB-led turns off slowly when I press the ON/OFF butto on the lcd for some seconds.

May I be sure that the problem is some capacitor?

Thank you.

I have removed C133 cap but I can see no oil under it. It seems clean.

With a ohm tester it seems to charge before going in open-circut.
Is it possible to test its goodness ?

Hi all.
I have an LG LCD TV model 26LX2R.

When I have removed the power supply, i have noted some oil in back of the PCB.
I have alreay readed [URL=http://www.fixya.com/support/t511962-lg_lcd_tv_standby_light_flashing_red]here [/URL] that samxon caps have this problem after they bulg.

The question is that I cannot see any bulged cap.

Can you help me with some advise to find the bulged cap ?
