Troubleshooting & Repairing LCD TVs by John Preher at
For someone new to electronics the first few pages of this book may be a bit challenging but the majority of this book is easy reading with lots of pictures,diagrams and useful troubleshooting techniques. Johns book gives you a good idea about the main test points you should look for and their approximate voltages.
How to troubleshoot and repair Switch Mode Power supplies by Jestine Yong at This book is a bit spendy but I'm still glad I purchased it. In my opinion it's a must read. Jestine is good at getting right to the main points you need to understand about troubleshooting this kind of power supply and its associated feedback circuits.
Since a majority of the problems I have seen on LCD TVs are related to bad power supplies I figured it will pay for itself many times over. Most of the book was easy reading with plenty of pictures and diagrams.
Testing electronic components and finding unknown resistor values by Jestine Yong.
I have not yet read Jestines book on Testing electronic components but I was told it's a good one for a person just starting out in electronic troubleshooting.
How to repair LCD Computer Monitors by Jestine Yong at
Even though this book was about computer monitor repair I found most of the troubleshooting techniques he demonstrates also applied to LCD TV repair so I was glad to have read it. Much like the book on Switch Mode Power Supplies it was easy to read and similar to Johns Prehers book on LCD repair but in Jestines own style. It had lots of pictures and good troubleshooting techniques.
Mikes TV case histories The latest paperback edition has 1300 case histories on LCD, CRT, Plasma and Projection TVs. at 1-410-272-4984
When I first started in the TV repair business and my troubleshooting skills were not that great often times Mike's case histories told me exactly which parts I needed to replace and it often saved me from having to purchase a great many schematics. I have been using his case histories since 1995 and I would not be with out them. If you call him please be considerate of his time zone and call between 11:00 AM TO 8:PM Eastern time only.
John Prehers LCD TV case histories at
This ebook has 56 case histories on nothing but LCD TVs
and which parts he replaced to get them going. I found this ebook was helpful in better understanding the connection between certain symptoms and their causes. Right now it's only 10 dollars.
Getting Started In Electronics by Forest Mims available at some Radio Shacks or through this link.

Another one of my favorite repairs are these antenna.

Connectors customers are always ripping them off.

They moved the TV set or the yank on the cord, and it gives yank these things right off.

And here I've got one that's been yanked up right here, I'm going to go ahead and fix it for the customer.

First thing I had to do was unsolder his tuner it's, a little section right here.

I'll show you how I go about that first thing I have to do is unsolder the backside of the tuner and I apologize for the poor quality video here.

And just sitting here alone in my shop doing what I do most of the time.

Anyway, this stuff called wire wick.

If you don't know about wire wick, you really got to learn about this stuff.

You can buy it at RadioShack it's.

It actually drinks up the solder when you hold your iron.

For example, when I want to take the solder off these different terminals here on the backside of the tuner I simply push the wire wick up against the terminal I.

Wanna do solder and I don't think the camera is able to pick it up, but it's it pulls it right off.

You move on to the next terminal touch, the iron to the back side of the wire wick again it.

And it literally soaks up the solder I actually did this tuner ahead of time.

So I don't need to go through the process, but I'm just showing you.

You can see all the solder that got sucked up onto the wire wick.

And now that I've got it.

All unsoldered I can simply pop my tuner modulate there, a lot of times customers bring these in and they're in pretty bad shape.

Sometimes I have to repair the circuit boards too.

And anyway, the way these work you you can see I just pulled off the side there I did that or rather abruptly I, usually like to take a marking pen and Mark how everything goes, because you want to put these back the way they came out, but you can see the side comes off here.

And on the other side, you've got a same thing.

Now you've got the circuit board exposed and you're going to want to find where you saw it on the new connector.

Now I buy I buy quantity quantities of these at a time because this is so common I've had as many as three people bring these things in in a week, winning antenna.

Connectors, put on and it's good business.

Anyway, it simply fits right in here.

And then you have to pull the back side here and solder it into the circuit board.

Now one thing that I generally do is I walk over to my grinder.

And I actually grind the sides of these of this connector before I solder it because the solder sticks a lot better.

I mean, let me show you exactly what I do here.

I just take this little brand new connector and I, and I rough, I kind of turn it.

I get precise with it kind of cleaned up this see now now solder will adhere to the sides of it real well.

And I also like to generally taper the edge of this down a little bit.

Sometimes these won't fit in the circuit board.

Here we go now I can just solder that baby on I have generally have to use my soldering gun.

Because of the fact that it's uh requires a lot of heat, and you don't want to overheat these things if you overheat them, you melt the inside of it I had a friend that he always likes to put a connector on it before he slaughters it to help stabilize the inside of it.


Now that I set the antenna connector in place.

I can I, actually, go ahead and solder it.

Now, these kind of want to fall over here.

So the first thing I like to do is I, take my soldering gun and I, hold the trigger get a good and hot before I try to solder it and I'll just try to tack tack it down on the edges.

And because because I pre sanded, the ground ground, the side of the thing, the solder sticks to it real.


So I put a little there, a little here, a little bit more to get it to flow better and that's going pretty good.

Unfortunately, got a little bit of a space there I'd, rather not have, but that's.

Alright, long as I don't short out that Center terminal I'm good.

Now, this is a little trick.

A friend taught me, it's, probably not a bad idea.

He generally likes to take some sort of an antenna connector and pop it on here as he's soldering it.

The reason he likes to do that is he sometimes the plastic inside here starts to get molten and soft.

And you get pushed to the side because you're getting this thing so hot to solder it, but that's, probably not a bad idea.

I'll, go ahead and do it this time just for the show and get this baby soldered on here.

Just about got it solder is flowing on there.

Real nice, I bet you this thing's, a whole lot stronger that was when it was first made I've never had a customer bring one back for a second repair after I got done repairing him.

So I think we're good.

All I got to do is pop the tuner back in and I'm all set.

Well, I almost forgot I have to head to resolder the back the back wire coming off.

The connector goes right here.

So I had to resolder that too that's, good and I generally, like when I'm done with these things I generally like to take my magnifying glass out and really look things over because a lot of times let's see if I can hold it in front of my camera and get it to work a lot of times.

You can saw our connection.

And if you're not careful you'll you'll have a little spot solder bridge going to somewhere else.

You don't want it or you'll lund saw it or something you shouldn't because you're, not being careful enough and you're causing more problems than you start with.

So you got to be careful, especially with the surface, mounted components, sometimes you can unintentionally unsolder one of them.

So just be steady with your iron.

And you should be fine anyway, I'd like to look over the board for cracks and stuff.

Sometimes you'll see little cracks by the way.

This is a 10 powered magnifying glass.

You can buy one similar to this called Jewelers loops.

If I didn't have this thing I'd be completely lost I, don't know, anybody that has I strong enough to see what you can see with a magnifying glass.

This enables me to find baddest bad solder connections and all kinds of things I wouldn't.

Normally be able to find.

So an absolute must in this business is a jeweler's loupe or just a magnifying glass.

I suppose, if you can find one that's, 10 power, so that's, pretty much ready to go I'm just going to slide it back together, I noticed a lot of times when I get done soldering.

These sometimes the case doesn't want to squeeze all together because of the solder around the edges.

So if you can do it carefully, it doesn't hurt to just put it in a vise and squeeze the squeeze of ice a little bit to make this thing going the wrong way there to make it fit a little tighter and I, remember one time a customer brought a TV back and the case had actually fallen off the tuner.

So I, really like to make sure that everything is on there, good and snug.

So that's, pretty much ready to go.

You can see that's rock so that's, not going anywhere now, I'll, go ahead and solder back in so I'm, just going to go solder the rest of these terminals in here, very carefully and put the back on and get paid I was thinking they're, probably so many people out there that have the same problem.

If there was some way I could just do these eight hours a day, I'd, get wealthy, I mean, it's so it's.

So common it.

It goes fairly quick as you can see I'm done everything's, pretty well soldered in there I'll double check just to make sure if it looks like a better all soldered in so yeah, we're.


One little thing I could say here about soldering iron.

So maybe I'll make a special video about that.

But getting a good soldering iron is a must - I'll explain that in a different video as you can see, it's all back and better than new.

So let's, all take care of.
