            You are kidding, right? This old TV does not use LED for backlights, it uses CCFL.

                        Replaced 4 bad caps that were swollen, and the ones next to them that were not, crap ton of bad solder joints on power supply.

                          Hi, all

                          I've posted a similar Q&A on alternative site but this site seems to be more focused in saving UPS.

                          The system is a SUA 2200XL Rev 7 230V 640-0800G Rev 7

                          I have UPS that has a strange fault, it does not show or indicate any load on the system, via display or internally coms, LED test front panel works all light up.
                          has anyone else seen a fault like this , operates but no load recorded, or just blown one of the important non replacable IC's


                          1. internal monitoring via cable direct into the CPU that no load is present even...

                          LG 50PK590 - three clicks and steady red light, won't turn on.
                          by Noah Glasse
                          Hi all,

                          I've got a LG 50PK590 plasma TV which upon plugging in will click three times and the red LED in the corner will come on and stay on, the TV however doesn't come on (no humming, sound, video, etc.) and using the touch controls or the remote does nothing. On exceptionally odd occasions, the TV will come on and work normally when plugged in and will last about 5 minutes before going back to off and unresponsive.

                          I've got the back off of it and none of the caps stand out as visibly buggered, I've also tested the three resistors in the corner of the power board which...

                          Board was just repaired, great thing for us since the DATA was recovered, however the battery was just replaced with a brand new OEM battery and holds the charge well, I plug it in and the charge icon comes on (lightning bolt) then it goes off and comes back again and repeats itself, The MagSafe 3 Amber light is turning off and on constantly, which is telling me something else is going on, before I pull this board out again I was wondering if anyone has come across this issue since its a little new to me on this model. Battery is holding the charge well at 52% but it won't charge further, I checked...
