Re: Leaking Cap or ink marking?
Yes readings are the same. A little more detail on the problem: the "pop" comes from the speakers. The screen goes blank, but the green light stays on, which leads me to think that in fact the TV is still on, just the screen (backlight?) is going out? Don't know if this helps. Thanks for sticking with me.

[B]IGNORE ABOVE POST I COULDN'T EDIT IT-- BELOW IS ACCURATE[/B]
OK first of all a zillion apologies for only being able to get back to this now... it turned in to a busy summer. So I was able to do what you said
And here's what I got with the TV plugged in, turned on, and the white internal connectors plugged in, both BEFORE the pop, and then a few minutes later, AFTER the pop.

Re: Leaking Cap or ink marking?
Thanks for your reply
Here is the best I could do, sadly I only have an iphone camera. I do have a multimeter (recently purchased) and I suspect I could figure out how to read DC
Again, all your help is appreciated!...

Re: Leaking Cap or ink marking?
Thanks to all for your responses. There is no evident bulging, as the accompanying photos suggest... so maybe it's not the capacitors.
Problem I'm trying to fix: Mintek LCD TV, connected to PC. Turns on and after several minutes, there is a loud POP, and the screen goes black, from outer edges towards center.
Turning TV off then back on fixes situation, but only briefly then it pops back off again. Happens with both VGA and DVI connections, different cables, etc.
Thought that sounded like bad capacitors...

Leaking Cap or ink marking?
Hi all--
Newbie here, have searched all day, but cannot figure out if these caps are bad or not. The are not bulging as far as I can tell, but some have these dark purplish marks, that look like they COULD be leaking, but also look like somebody could just have taken a marker and marked them.
This is from a Mintek DTV-260 LCD Color TV.
Many thanks for all your expert opinions.
Best
R...
