Hi,
I would just to share with you my experience with Pioneer Service center, yung main distributor yata nila ito, yung authorized distributor lang ng plasma tv.
I had problems with my PDP-427 nung June. Some pixels go black kapag super white yung background. Pero di siya dead pixel kasi sa ibang colors, ok naman siya.
So tinawag ko and may technician na pumunta sa house para tignan. Di niya din sure kung ano yung problem, so pinapull out yung unit.
They tried replacing the board daw pero ganon pa din, so iniisip nila baka yung panel mismo sira. Sabi ng Pioneer Singapore gusto din daw nila makita yung problem. So ayun, pinalitan na lang yung panel ko, so parang bagong tv na din ako.
Lahat yon happened in a span of 1 week. I am so happy with the service ng Pioneer. Sulit na sulit ang bayad ko sa kanya.
