First post guys.
I've read all the Panasonic post but found similar post to this but not for my model and no resolution.
My Panasonic W28R3DP has started popping it speakers.
It's like a HV or static crack- the sound usually dies for a second then comes on again.
I'm at my wits end....
This always happens within the first 10 mins of switch on from cold, but has happened when the sets been on for hours and is warm.
I think it's affecting all speakers but at least the centre one. It also affects line out as I've an sub which obviously exagerates the problem ! Thump !
Just hoped someone had come across this before ?
Things I've done already.
1) Checked for obvious failures.
2) Checked for dry joints
3) Checked the HV anode is not arcing to tube.
4) Check over sound sub pcb for obvious failures
5) Ran the set in the dark to see if I can see any arcing - non seen :-(
Has anyone experience this before ?
I'm begging to wonder if it's a HV cap or a electrolytic drying ?
Any pointers much appreciated.
Set is around 7 years old
Thanks
