Got the red blinking LED of death. (power light just blinks red, tv will not turn on) TV is about 2 years old.
Did a little research on the web found that it is a common problem, with an equally easy fix. capacitors are shot. So I took it apart last week to figure out which were the problem, turns out there were 4 that showed bad. (top bowed up instead of flat) Ordered the 4 capacitors online, $10.78 shipped. They arrived and I under took removing and soldering in the new ones. Took about 15-20 minutes to resolder, put TV back together. hit the power button . . . . . . It LIVES . . total time dis-assembly , solder, re-assembly probably took an hour

I was a little concerned about soldering on a circuit board.
I've done a lot of welding, brazing, sweating copper pipe, some soldering of electrical wires. never a circuit board. nothing really to loose $11.00 worth of capacitors. TV was already broke

I did the same for my Viewsonic 20 monitor. Apparently, there was a year of capacitor production at one of the largest OEM sellers of capacitors that were defective and would fail early. I soldered in two new ones and fixed it. I wish I could tell you what year's production that was.

Dude, can you fix my microwave too? Damn thing shuts off like it lost power sometimes by itself or usually when the timer ends. I open the door, then close it and then it comes back to life. I need to pull the case off and check it out. Replaced the main fuse in it years ago when it tried to die on me. It's served me well the past 21 years!

Bad caps yes. But electrolytic caps die from heat and ripple anyway.

Mines a Panasonic, same size and also LED. We have had trouble getting it to turn on in the past, but being an electrical idiot I figured the TV was toast. Now I know that I'll be able to tear it apart and spend another $11 before I have to toss it.

I did a Samsung that I got for free a couple of years ago.
$16.00, about 2 hours of my time (including beer time and cleaning the dust bunnies out of the tv while I had the back off). Display has been working great ever since. |

Its amazing what gets thrown away anymore for lack of very inexpensive parts.
My wife's dehydrator quit working and she was ready to buy another, it needed an .89 thermal fuse. She was actually disappointed (she wanted a new one) but admired my skills....... LOL She is convinced she is cursed because she will never own a new major appliance or vehicle again since I usually can fix them. I have a 1978 vintage RadarRange that need the caps replaced in the touch panel, my next project, its built like a tank and I can't bring myself to throw it away! LOL Good on ya OP, I have a 42" LG so your story is interesting........ |

Fixed my FIL TV, with the same repair.
Though it took me all of 10 minutes. I had all the parts in my garage. So basically it was free.Wife had never seen me repair or fix things like a TV. She was amazed. I am surprisingly full of good stuff, according to her.

Nice job. It feels good to fix something.
Last weekend my wife tells me that we have to buy a new portable DVD player (my two year old son watches it in the car) because the screen no longer works. I investigate to find that the screen is most definitely fucked. I figured that since I was going to have to replace it anyways, I might as well try to fix it. Opened it up to find the ribbon cable that goes to the screen kinked causing it to fray at the end. I straightened it out and secured it to the chassis with electrical tape. Put it back together, and it has worked fine since. That is $100 that I can spend on ammo or mags instead of another DVD player.

Thought the cheap ILO LCD tv we have had the capacitor plague. Opened it up and found that a trace burned on the power supply board. Soldered in a jumper and good as new.
My old ASUS mainboard has the plague tho. Leaky caps everywhere  Debating if it's even worth it to fix.

Nice fix! I like resurrecting stuff with the multimeter and soldering iron.
If it's broke, I figure there is no harm in pulling it apart and having a look. I am better at larger soldering jobs, though. I have fixed a couple SMT components but it was ugly.

Lot of the new flat screens have cap issues. TV in our guest room went out, and it was two burned caps. Couldn't find the right cap (6kv 39pf) from any of the major parts houses, (I know you can stack them), so I get them from china (eBay). Little over five bucks for ten including shipping.

Hmmm. I have an older LG, also a 42 inch. Never had a problem and never heard of this issue.
Good to know, though. My soldering skills suck, but I have a buddy who can build and repair electronics who'd probably do it for ammo. |
