Hitachi (Vestel 17IPS20) 50HYT62U.
« on: July 16, 2018,13:02:06 »
Hi folks,

Had one in where the mains fuse and bridge rectifiers had popped (17IPS20) Thought the worst but noticed with a series lamp that the PFC transformer (TR100) was smoking a bit. Seems it had run hot and shorted primary to secondary.

Had a spare from an otherwise duff panel, and surprisingly the set worked. Gather the secondary goes somewhere, but couldn't sort from the schematic where it goes to, though one end goes to chassis.

Being dubious, got a spare board from Ebay, just in case it poops - Chris.
