hitachi P50TO1u psu problem.
« on: November 02, 2010,13:26:29 »
hi got a hitachi P50TO1u plasma in. set is dead suspect psu problem.

on inspection i noticed 1 trace was burned on underside of psu board.

also 2 resistors had burnt out.

repaired the trace and replaced both burned out resistors.

tested tv on low voltage on the variac.

i have noticed the 2 new resistors i replaced on the psu are overheating and getting red hot to the touch..

anyone have any ideas or come across this set or psu.

i have attached a picture of board.

thanks
