Hi, I have a samsung LCD that will not turn on when connected to a input. If you take all cables out, the tv turns on and displays no input.

When an input is connected, sky via hdmi or scart or DVD player via hdmi or scart the televisions cuts out. And then keeps trying to turn on. It makes the start up noise repeatedly, flashes the content on the a screen and then turns off. Then tries to restart again.

Does anybody know the how to fix this?

Thanks for your help in advance.

It 'might' be the common crap quality capacitors causing the problem - how old is the set? (because some people here claim that in later sets Samsung improved the quality).

Television is 5 years hold but has been in spare room and hardly used. I have put it in my office for the past two weeks. It has been on every day for 1 week and now stopped turning on

Model number is LE26R87BD
26 " Model

Just out of interest have you tried it on an aerial? Or is that the same as when using Sky or the DVD player?

There is a chance it is dodgy capacitors. If you are competent with a screwdriver and soldering iron and know what to look for, identifying dodgy capacitors is not that difficult. And swapping them out should be possible.

Just depends on how much hassle it is to get at the circuit board and your skill level.

I have just taken out power supply and there are 3 capacitors that are bulging and slightly leaking.

I am quite competent to take them out and put new ones in. The capacitors that are bulging are 35v 1000uf.

What capacitors should i replace with?

35V 1000uF

It's not the value they got wrong (though it could have been) but the quality of the components they used. Basically they used the cheapest and nastiest ones they could lay their hands on and they didn't have a particularly long service life.

So swap them for something decent of the same value and you should be OK. Just don't stick them in the wrong way round or you'll have an even bigger mess to clean up!

Panasonic do a decent range, something like this

Another quick question.

Where can you buy capacitors? or is it just ebay or amazon?

See the link above.

Plenty of other places. Even Maplin if you want a "High Street" store to visit.

Trouble with some online retailers is they may do a minimum order value or charge a handling fee for orders under a certain value. Which can bump up the cost considerably given how cheap capacitors are.

You can buy them at any good electronics supplier - CPC (Farnell) was mentioned above, RS Components is another good source.

What you want is good quality 105 degree caps, low ESR if possible - Panasonic and Rubycon are good makes to go for. While you can buy capacitors at Maplin, they are only likely to be cheap ones.

You should also be aware that they might be other faulty capacitors, not all faulty caps bulge - although any bulging cap is faulty But try replacing the bulging ones first, which will probably cure it.

You could be right about Maplin. Sure I have been in there and bought some Panasonic caps (OK a lot of years ago ) but their current offerings don't look all that inspiring.

Thanks for all your help. I ordered some replacement panasonic capacitors from PL1 Electronics via ebay. Ordered thursday night and arrived saturday morning.

I replaced the bulging capacitors and all working fine now. So pleased. Would have previously thrown TV away. Now repaired it for £5.

Many thanks all.

Well done, I'm pleased you got it sorted
