    You can try force on the power supply board again but this time have a 4.7 (4R7) Ohm 5W (10W preferred, since 5W will be at the limit) connected to 5VSTBY output and the see if the C946 Voltage will go to 14 ~ 15V when using force on and the PFC will stay on or not.

    So far we get the two 47" boards, one 37", and one Stereo receiver (bad brown out resistors) fixed, now you only have the 46" one to deal with.

            UC3842 Power Adapter Blowing Fuse
            by Dannyx
            Good day folks......wow this new layout is weird. It's like I woke up one day and I'm no longer on Planet Earth or something

            Anyway....got this here power brick from a USB to SATA adapter which keeps blowing the fuse after I almost repaired it. The reason I even bother to fix a power brick (wall wart, whatever) in the first place is because this thing was really convenient to use: I'd just plug it and that's it. It's a dual output supply, for both 12v and 5v, which although I COULD easily obtain with a DC-DC converter from a standard 12v adapter, I thought I should crack open the...

            Samsung PD27AOQ (BN44-00506B) constantly blowing internal fuse.
            by Tips
            Looking for some assistance please.
            Trying to repair a PD27AOQ samsung power board.
            Initially had the typical problem of cm806 capacitor blown, additionally thermistor NT801s blown.
            Replaced the ceramic capacitor, str60252s, bridge rectifier, thermistor and fuse.
            Testing it the fuse blows immediately power is turned on.
            diodes dm852 and dm853 test as shorted when in the board but fine when removed.
            any assistance, guidance would be appreciated.

            Samsung 46" TV LE46B530 blowing fuse
            by RogerH58
            Hi all,

            I am a newbie and not very experienced so bear with me if i struggle sometimes with technical language - but I'll do my best. I searched "Samsung" and the model number on the forum but didn't find anything I could understand!

            I'm not an electronics guy - just picked up stuff over the years through my flight-simming hobby.

            I have the above mentioned 46" tv as the monitor for my flight-sim setup. Recently it went "crack" and stopped working. No standdby light and no response. I assumed a fuse had blown and after investigation...

            A funny fuse story – Lumix LX100 II
            by corrize
            Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
            I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
            The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
            There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
            And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping...

            Philips 47PFL4606 Powers on, works normal then powers off after a minute
            by simwalsh
            Hi,
            I am new to this forum and have searched for some answers with problems similar to mine.
            Philips TV powers on as normal for about a minute or less then click and no power at all not even standby light. If i disconnect from mains and reconnect it will power on again but for a shorter time. Once i leave it disconnected from main for a longer time it will power on for a longer period the next time.

            It sounds like a power supply issue?

            I have the board out and want to run some tests. Not sure what i should be doing but i put a 1k resistor across SB and +5v...
