I would say the best one is made by Peak Electronics. You want one with probes so you can test capacitors in circuit.

As for instructions, Google is your friend but here's a starter:

The DE-5000 is cheaper, more versatile, and more accurate. But yes, you have to figure out to press a few buttons to use it.

Frankly, for this purpose, both are overpriced and will never be seriously utilised. The little £20 things do fine.

Hi Guys,

Sorry for the long delay, been away.
Anyway, I've had a look at a few meters and have decided on the one below.

Can you please let me know if this is ok to test the capacitors on my tv?

That meter from the book seller measures only capacitance - not ESR. See my previous reply for recommendations.

(Note that buying from the book seller means sending money out of the UK, to a company that (quite legally) pays very little UK tax. Buying from a company such as Peak Electronics in Derbyshire means supporting Britain. When we end up destitute like Greece you'll all be complaining but it'll be your own fault.)

Since i dont have alot of experience with electronics,

In that case, how is buying an ESR meter or anything else really going to help?
If one or more capacitors test as faulty, what will you do?
Is desoldering the faulty capacitors and soldering in new ones something you can realistically do / have done before?
Even if you do that, what if the TV still doesn't work?

Realistic options:
Put TV on ebay, sell for parts only, get some money for it to put towards a new TV.
Or find a local TV repair shop - such places do still exist.

I would avoid the multi-purpose meters and buy an ESR meter. K.I.S.S.

Hi Sam,



Can you provide a few example esr meters i can have a look at (preferably good cheap ones)
And also any easy to follow guides on how to test the capacitors.


Cheers

In general you can get things that are good, and you can get things that are cheap, but you can't get both together.
