Hitachi 65 Inch Rear Projection TV

[kgg_1]

I am working on a Hitachi 65" Rear-Projection TV that had Pico-Fuse E907 ( 3 Amp ) Blown on the Power-Supply-Module, which was "Blown-Out" due to "Shorted" "QHO1" Flyback Output Transistor ( 2SK2771 ) "Power-Enhanced Mos-Fet". I recently replaced these Two-Parts Only-To-See them blown out again about 25 days later. I suspect that IHVT Flyback "THO1" has an intermittent issue taking out "QHO1" 2SK2771 again. The Deflection Output Panel is DP23/80 and the Power-Supply Panel is DP2X. Any rare but intermittent known issues here to so soon take out QHO1 and subsequent 3 Amp Pico-Fuse again in 24 days of great operation after initial repairs and replacement of same parts..
