Re: Samsung LN46A550 Power Cycling

Has anyone had the parallel fix fail on them? I replaced caps and did the parallel fix 12/2016 and my LN46A550 is starting to show power issues again (power on/relay/power cycle, finally on or occasional green screen). I'm debating if it's even worth opening up again at this point?

Re: Samsung LN46A550 Power Cycling

Thanks to everyone in this thread but especially budm and Terryfictv! I was able to fix my LN46A550 that had reached the point of not staying on at all through hours of power cycles. I soldered 100uf caps in parallel with C102 and C131 and all seems fine now; it powers on just like it used to many, many months ago.

budm, first of all thanks for the extremely well documented pictures. Also, it seems that you've done a number of these repairs, have any failed that you've done the parallel fix on?
