Samsung UN55F9000 Dead (Lightning Damage)
This set is dead due to storm damage. There was no output from the power supply and after checking all the fuses(good), I visually inspected the board and found the top blown off of ICS801S, an 8pin dip with D3011k printed across the top of the chip which was the only part left of it. I haven't been able to find a s/m for this supply BN44-00675A and find no USA suppliers for this chip. Any help out there? -
Vizio VO47LFHDTV30A Dead Set
This set has a 0500-0407-0680 (DPS-280LP) power supply. Through troubleshooting I found Q901 N-ch Power FET shorted which I replaced, along with R908 an SMD resistor open. The value of this resistor was blown off the top so I have no idea of the value. I have searched for a schematic for this supply to no avail. Does anyone have a schematic from which they could give me the value of this resistor(R908). Thanks much for any help. JMHammond -
