Hello!
I'm from italy...
I own a panasonic kx-p4420 printer, this printer worked fine since the first
day.
Now it's dead.
It won't turn on, no power , no light , no noise. Totally dead.
I have searched trough the news , and trough the board and this seems to be
a common issue,a common problem with these printer.
I'm a good handyman ,i've tried to repair it but i don't know where to look.
At now i've removed the power supply ,all the fuses are good.
I got power from the switch in the front panel.
What to look now?
What are the "COLD SOLDER JOINTS" ?
What is and where is the THERMAL FUSE?
What other can i look for?
Thank you very much.
I forgot to mention that sometimes before the total dead, the printer comed
on after one or 2 hour of sleeping with the power button on. !!!!

The boards seems to be good except for some few wear on it.
If you need i can take a pics of it and send trough e-mail.
Thank you in advance
