Sounds like dodgy caps, when warm ie on/standby they will stay in tolerance until removed from the heat source

philk: I thought that one side would be constant voltage - positive side? should they not all be 234V or 234V and then another volt of some sort? maybe DC

The low voltages in the range 0.2 to 1.1V are likely to be along the Neutral leg i.e. very small voltage drops across the chokes in series with that leg.

How old is it?
I know it will be out of warranty - but someone usually suggests the consumer guarantees act at some point.
Maybe worth checking out...

Probably about 18months old - out of warranty I think they are only 12month

If its as new as that I would carefully hide the evidence that you have been fiddling and have a quick look for your rights under the consumer guarantees act.

Search geekzone - there is plenty of reference to it.
In a nutshell - never mind what they put in writing (12 months) - you have a right to expect X number of years out of a TV and it has failed.

Who did you buy it from? - you probably have to go through the retailer - but read up on your rights first...

Actually - read this:
http://www.consumeraffairs.govt.nz/pdf-library/publications/Your-Consumer-Rights--Goods.pdf
Page 19 sums your situation well.

The whole problem with the act is what is 'reasonable' expectation of the life of a product. Have a rummage on the consumer website. In the case of a TV then yours would seem to have failed in an unreasonably quick time.

Let's try something simple here, the Panasonic Plasmas have a proper mechanical switch on the front acting as a master power switch, off the top of my head this is wired directly into the HV Power Supply, test this switch is working with the multimeter by unplugging the leads heading into it then seeing if you can get the switch to short when on the [on] position.

Hang on - what?

Post a thread on Geekzone showing you've taken a set apart, then try and hide the fact you have (despite having pulled it apart), then take it to a store and lie about having taken it apart...

robjg63: Are you suggesting that the OP should be fraudulent in his behavior? What happened to being a straight up, honest person?

If it's only 18 months old you had a legitimate repair or replacement claim under the CGA (failed within a reasonable lifespan) which you have now blown by delving inside the set and trying to sort it out yourself.
You should have gone back to the Retailer as soon as it stopped working. Your best options now would be to try and obtain a replacement power board from Panasonic spares and fit it yourself (no guarantee that it will work), take it to a repair facility (maybe uneconomic repair), or buy a new TV.

I am assuming here that he hasnt actually done anything more than run a multimeter over a couple of components and has not tried actually modifying the TV.

By 'hide the evidence' I actually intended that he screw the back on straight away.

I had assumed initially that the TV was quite a few years old - which it apparently isnt.

And trying to push cga after 12 months isn't nearly as much fun as removing some screws.

You're not on Atlantis anymore, Duncan Idaho.

Try for CGA and see what happens... might be surprised and find its sorted. Worse case scenario is that the agent takes it apart and finds that someone has already had it apart, and refuses to repair for "free" and youre no worse off than you are now, but at least you know CGA wont cover it now.

Just rang place where I brought it from, they told me I purchased on 11/4/2011 so it's a little older than I thought.
They said you can ring Panasonic about consumer guarantees act on it but didn't offer anything else
