19" KDS monitor model:XF-9P,chassis:C812
19" KDS computer monitor (flat
screen),model:XF-9P,chassis:C812,year:Feb 2002,LG Electronics (Goldstar) CRT,UL Listed:7K04 (Sampo).Problem no power I found Q706=2SC5584=NTE2533=SMPS x-fmr transistor is shorted due to cracked solder connections at the base signal drive components: R723 D705 R734 D706 R720 R721 T701=horizontal driver x-fmr I replaced Q706 the monitor powered up with hv for a second then a chirping with an increasing rate from the power supply so I now D706=BY459F (diode connected to collector and emitter of Q706) is shorted but the new Q706 is fine. I would like any common repair tips for this chassis before I replace D706 and I would like a possible NTE substitute as NTE does not list one and this diode comes in a rectangular case that is screwed on same chassis heatsink as the SMPS x-fmr transistor (Q802=2SC5339). I don't repair computer monitors because usually about 70% of them have defective flybacks but I rang this one and it's fine.Thanks in advance. Note:this unit is similar to 19" HP computer monitor M90 model:D6433A,chassis:C812 Sidney Dartmouth,Nova Scotia Canada O |\ __O _|_| \ |
