Panasonic TH-46PZ81B - No go, at times.
Turnip:
Thanks Bruce,
Chap who does the leg work took it back to find the mains extension socket rather Brown, and the set wouldn't come on. Not a word since - Chris.

Greetings Chris, from the nether regions,
Power supply on these has been incredibly reliable except for the monolithic chip cap (1uF) on the small modules MC201 and MC301, but these caused code 2 and 10 respectively, and can be intermittent.

Anyone care to point me at which cap? I have a set in at the moment with a code 10 and it has to be worth a punt trying that.

Here you go Dave,
The blue cap on the upright module MC301 is usually the culprit. The original is a tiny chip cap off pin 13 of the ic. Do not replace it as has been done in this case. Merely remove it from the module. Bruce

Thank you, you are a flippin genius!!!!
I was on the verge of ordering the repair kit which wa a new SMD chip and a new capacitor. So I thought I would try your suggestion and just remove the offending cap.
The set is working!!!!!
Do I just leave it like that and give it back to the customer, or fit a new cap?
downunder:
Hi Dave, just leave it as-is. The set will functions quite merrily without it. We used to replace them but it was a tricky manoeuvre
given the size and flimsy nature of the solder pads.
So that cap on MC301 causes code 10, cap on MC201 (identical) causes code 2. An invite to a roast dinner would be nice except we're worlds apart.
