Is your [electronic device] broken? Don't throw it out!

Anonymous (@) 9 years, 3 months ago

How many of you know someone with a tv that broke, or a computer screen, or a fridge, or something of the like? Maybe a cracked screen on an ipod or a phone?

What did they do? Throw it out and buy a new one? Well that blows! The poor planet. Slaved really hard to get that, and instead of fixing it, it got tossed.

Let me tell you how to fix over half of all broken LCD or Plasma TV’s (a real issue, a cheap fix).
If your TV does the following you may be in luck;
When you turn it on, does it initially act like normal – the power light comes on, makes a clicking sound like its powering up, and then… nothing?
When you turn it on does it simply turn itself off right away?

Take apart the TV. What you want to do is take the entire back panel off to expose the circuit boards. What you’re going to look for after this is usually easy to spot; a blow capacitor. These are very sensitive to high temperatures, and due to the nature of leaving TVs on for extended periods, and being of very high amperage and voltage, high heat can accumulate. Especially in hot humid summers this can ruin a TV. Go here to look at a picture of a blown capacitor:

A normal capacitor will, at the top, be perfectly flat. A blown one will expand and break the top seal, exposing some electrolyte or fluid or solids. These have to be replaced.

Desolder them with your soldering gun, make a note of where they are on the board, record their VOLTAGE and CAPACITANCE. Unfortunately these are completely worthless now, not really able to be fixed (planned obsolescence).

Replace these from radioshack or from a quick google search.

Start surfing the tv (wait why do you watch TV?).

This goes with nearly any electronic that heats up and fails due to heating. Computers unfortunately aren’t always the same – sometimes the motherboard can go or the processor, these are expensive to fix, and due to the soldering impossible for the average human. However, some power sources of computers have been known to go out.

If you can’t fix it – for the good of the world send it to a repair shop. Its not cheap, but it saves so much energy and resources from being absolutely wasted. If you really care about being a good human – repair it. Got a rip in your pants, sew a patch. Shoes coming apart, see a cobbler (what a great word). BORROW a vacuum cleaner. BORROW a lawn mower – don’t buy a new one. Nobody uses these every day and a good neighbor shouldn’t mind lending one out.

All for now. Please tell me your repair / fixit stories.

Oh and to extend the life of all computers, take them apart (Carefully!) and remove and dust that has accumulated from the intake fan. This is one of the most common causes of a dieing computer. If it takes more than 1 minute to boot up your computer – see if some dust hasn’t settled on the processor.

Nobody? Really?

Thanks man, I’m gonna pass this knowledge on to a friend whose TV broke during a lightning storm. It’s possible the circuit board is fried, but if it’s just a capacitor it will be an easy fix :)

I would have though more people would find this useful.

like you said, i don’t watch t.v. I’ve had the same lcd screen for 3 years, doesn’t seem like a common issue for them to blow. Nothing else I use has a capacitor like that… dvd player maybe? idk I use my computer for everything.

My roommate has an issue with his TV though, tell me if you think this could be the fix. It turns on fine, but randomly after having it on for a period of 30 min. to 6 hours the screen will just go black and start making a crackling sound through the speakers. It starts as a pop then accelerates like popcorn until it’s white noise and you have to turn it off to let it chill out for a bit.

He’s so frustrated. It’s probably blow his mind if we could fix it with a twist of the screwdriver and a run to Radioshack.

All flat screen TV’s have the same problems and the same fixes all flats have 3 circuit boards like he said if it powers on but turns it self off then it’s the power board if you have power but the sound and picture are messed up then it’s the t-con board if you have power and sound but no picture then it’s the main board most of the time it’s something blown on the board which if your good at soldering very easy and cheap fix if not just buy the whole board a little more expensive but you don’t have to worry about soldering and the board are easy to install their plug and pulls

@versai, sounds like yeahp over heating. Try the above. It is one of the most common reasons they “die” other than dropping them.

@ijesuschrist, Bummer, he had like 6 caps but they all seemed flat and sealed. Thanks for the guide though, was easy to tell.

I just found a Lg Plazma 50 it the trash. The screen isn’t broken and powers up, it look like the screen is blinking. any help would be great.

Replace either the main board or t-con board that should fix it best way to find out which would be to do a online search on the make and model of the TV and the problem it’s having this should narrow down were the problem is

@gofast325, take off the back and look for blown capacitors.
