A friend has two large Plasma screens with burned out power supplies. He's a Broadcast Maintenance Engineer at a 24 hour news channel and can
fix any electronic equipment if he has a schematic or can identify the parts.
These units are NEC PX-42VP4A
Does anyone have a schematic, service manual or insight into where to get the following part, BLQH, which looks like a surface mount transistor or insight into what the equivalent parts is?
NEC has been unresponsive to requests for a service manual or schematic.
Thanks all
