TV problem

Panasonic plasma, just under five years old, sounds to me like power supply tripping out when switched on. Blown capacitors? Amazon (quick response) say speak to Panasonic first. Panasonic (slow response) say sounds like motherboard, needs to be inspected and they give me the number of a service guy (but not been able to get hold of them yet). A fair amount of stuff on the web about how to diagnose boards, but arguably obsolete technology so not worth spending much money. On balance better to whip the back off and poke around, rather than getting a man in? I have some electronics experience, plus DVMs (and an oscilloscope, for that matter).

I'm very happy with the Humax HDR Fox T2 off eBay, with hacked firmware. Pulled my first reciording off it yesterday to make a DVD!

Panasonic used to make nice loudspeaking phones. The latest offering has half the volume level. It's just a rebrand exercise.

1st step: identify the power supply board, it will be where the mains cable goes to. 2nd step: read off the board's part number. 3rd step: put the number into Google. Similar TV's might share the same board, but different screen sizes will have different boards. 4th step: see if a UK supplier exists. There used to be a guy in Glascow that stocked everything like this.
