Has any one who has expirenced buzzing / electrical noise from thier 42PD3000 had the problem rectified by having a modified transformer fitted?
My transformer was upgraded at the end of February 2004 after my wife & I grew tired of the constant changing of he buzzing frequency when the picture content changed. This buzz could clearly be heared above normal listening levels and obviously spoils our viewing experience. The mod seemed to lessen the problem but we were not totaly convinced. Now just over one month later the buzz is back and worse than ever.
I reported this to Hitachis service agents, who had carried out the mod , who responded that the transformer was up to current spec and that there was nothing further that they could do. After some twisting I managed to persuade them to contact Hitachi. As yet I have had no reply.
Presumably, either the modded transoformer has failed or this is not the answer to our problem and I am interested to know if any one else has had problems with the modified transformer.
Many Thanks
