I am looking for a multi meter or volt meter what ever it's called under $25 any recommendations? I wanted to test out a power supply for a tv. It is an LG 55lb5900 any advice?
Oh, by the way: I have a 2013 42LA6200 LG LED tv set that started acting up. It turned out to be one of the led's on the strips inside was intermittently shorting out, and causing the switching power supply to trip out. I watched a Youtube video on how to replace the strip, bought one from Ebay, tore down the tv set, and replaced it. I then put everything back together and it hasn't failed to this day. That was over a year ago, and it's still working fine.
Let me warn you though: IF your tv set has the same issue (likely), the actual lcd screen itself is like handling a large sheet of newspaper, very thin, and very floppy. It is EXTREMELY easy to damage. If you do so, you might have issues depending on where it got chipped or cracked. Then again, if your tv set would otherwise be a throwaway, you might as well give it a try if you suspect a bad led strip is also your issue.
P.S. Once you replace a bad led strip, turn DOWN the backlighting setting as far as you can to still see a good pic, but not so bright (no need for "torch mode") that it can cause more led's to go bad.
