Howdy Gang,
I'm having a go at repairing my Panasonic TV - TH-P42X10A.
Symptoms - None. Completely dead. No power on LED - Nothing.
My first thought was a blown capacitor in the power supply - its about that age - 25 years old or something like that.
Pulled the back off - on visual inspection - all the caps "look" OK - no swelling/bulging/leaking etc - and no other outward signs of nastiness.
So start from the start.
Power is definitely coming out of the wall.
Power is definitely getting through the power cable - 240v at the plug end where it goes into the TV.
Power is definitely going into the Mains line filter.
Hmmmmm - only 4 or 5 volts AC coming out of the filter and going to the board.
I've got to admit I've got very little idea about this filter. Its a TDK-Lamba EMC Filter. RPEN-04808EA-00A (photo attached).
Should I expect 240v AC out of this? If yes - well - looks like I've found the trouble - replace this (or maybe open it up and see if there is anything fixable inside), and it should be good to go.
If no - well then I'll keep tracing things down the line.
Yes, yes, yes....if it is the filter - they are pretty cheap. but what would I learn from simply buying a new one and plugging it in - I'll have a look inside to see if I can fix anything just for the fun and see what I can learn.
Thanks for your advice
