TV has started playing up and taking a while to turn on, tries a few times, chimes etc... And eventually gets there, but quite annoying. 
 
Seems its a common problem to do with cheap capacitors, anyone on here fixed it themselves? Seems I just need a soldering iron and a few replacement capacitors?

Yeah simple job, maplins sell the capacitors for about 59p iirc. I'm followed a guide on YouTube.

Most places local to me quoted around £80-100 to fix it, make sure you get a soldering iron with a fine tip as it makes life a little easier

Seriously? A business is going to charge you for their time?? What a rip off!

I didn't say that was a lot, but if its the problem it seems to suggest, I'd rather spend £20 on a soldering iron and a couple of capacitors.

You'll want to replace every cap on the PSU.. You cant tell which ones are buggered without removing them and testing them.

If they're electrolytic capacitors then you can tell if they've popped by looking at the top of them - they will either be leaking or they'll be domed on the top: 
 
  
 
Though if it's a similar sort of problem to the one I had with my first gen Sky HD box, you'll want to do the lot anyway as they use poor quality capacitors on them which caused all sorts of issues.

They can still fail without bulging.. I've fixed a fair few PSU's and only a handful have the caps bulged or leaked..

From what I've seen on YouTube, they should be bulged. I'm not gonna fuck around with it if I'm not positive, but I'll open it up and have a look at least. 
 
It seems to be a common problem because they used cheap capacitors

There was a bad batch of capacitors years ago, affected loads of stuff. Dell had a motherboard replacement scheme that went on for years and years because of it. 
 
This may or not be related to that.

A lot of it is down to manufacturers using CAP's on spec (instead of over-spec'ing) and the life span is only about 50,000 with nominal load..

Had this on a brand new smart TV, bought from John Lewis and withinf a week it kept turning itself on or off regularly. 
Google suggested same things, but as was brand new we just had a replacement

Fixed it yesterday, cost £12.80 including the soldering iron kit. 
 
Soldering isn't exactly high quality, but works good as new now
