LCD TV problem

Hello clever guys,

Please bear in mind I don't know much about electronics, but I am asking for advice really.

I have a 32" LCD TV (LG Electronics) about 3 years old. Recently I have noticed a distinct "shimmer" on the picture, most noticable when first switching the TV on. After it warms up, it is not really noticable until you put on some on-screen menu, or an image with sharp vertical lines - but it is definetly a lot worse when the TV is cold.

So being an adventurous type, I thought I would take the back off just in case I could see something obviously wrong (this has worked for me in the past, believe it or not!) my idea was maybe there was a lot of dust causing some chips to overheat, that kind of thing.

Anyhow, there was no dust, but I inspected the MB and noticed 3 capaitors that look in a bad way...they have their insides leaking out! As a human, I know that if MY insides were leaking out, I would not work too good!! I assume this capaitors work in the same was as humans in this respect.

So, my question is, could this be causing my "shimmer"? And if I buy 3 new capacitors (I assume these things are cheap cheap) and some nice chap to solder these in place of the sick ones, can I watch my TV in its former glory?

Thanks for your time.

Wonderful post ... I am still laughing. Hey, go for it. Change the capacitors and see what happens.

Yes, if the contents of the capacitors has not damaged the circuit board, this may solve your problem. You should check for other bulging or leaking caps and change them too.

Thanks guys, this is all I needed to hear. I don't think the circuit board can be too damaged, as the TV still have an excellent picture after a few minutes. I will get them replaced and let you know what happens.

Cheers!

The electros are cheap, but those nice chaps are damned expensive to buy - had you thought about just renting one for the day instead?

It might not hurt to take a small toothbrush,and a bit of iso/rubbing alcohol and carefully clean the capacitor "goo" off of the circuit board too.That stuff is corrosive,and may cause problems later on.

I have found someone at work who can do soldering, so thanks everyone for some good advice. Cleaning the goo off the circuit board sounds like a good idea too (I will use my wife's toothbrush).

If the electrolyte sits on the board for long, it will be damaged. That stuff corrodes copper like crazy.

If you do, you'll need a new toothbrush, or a new wife.

Hi!

I'd strongly suggest the new toothbrush route. :-)

What if the wife is already out of warranty?
