Re: New Members - please post your introductions here

Hi all,

Good forum and lot of information. I am basically doing repair work in Textile machinery panels. Recently my TV Sony KDL-42W650A gone dark. Diagnose is done and TCON board (T420HVN04.3-AUO) has shorted PNP transistor. After replacement same is getting hot. Seems to be some more problem. While Searching for schematic for T420HVN04.3-AUO TCON board stumbled to this site. Hope to get information and any help in industrial Drive, and controllers.
Thanks.
