                  At least check the resistance between legs of the devices mounted on the heatsimk first to see if it shows very low resistance.

                      LG 37LS5600 blows main fuse
                      by dimis7
                      Hi all,

                      Need some advice to troubleshoot this TV.

                      PSU blow the main fuse F100, 3.15A.

                      I replace the fuse with another 3A (but not ceramic) and blows it again after few seconds when i plugged in to the wall, with nothing connected to PSU, just the power cord.

                      I checked with DMM for dead sorts but didn't found any.

                      Checked bridge rectifier and seems ok.
                      Also check main filter cap with transistor / cap / esr tester (the usual cheap transistor testers from ebay) and found ok.

                      PSU p/n is EAX64405901 (1.6)...

                      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.

                      Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
                      by cheeky2
                      I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
                      Obviously the same LVDS connector for the screen connection...

                      Sceptre U550CV-UMR 4K LED, Bad Caps on Main Power Board?
                      by Dani_2024
                      Hi and thanks in advance for any input you might provide!
                      I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
                      Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO

                      Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

                      Panasonic SA-MAX770PU SMPSU board fault....
                      by Rictech
                      Hello everyone. 😀

                      As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
                      Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.

                      Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
                      This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
                      There are no devices that have exploded or otherwise show signs...
