How Would You Like to Fix Your Own Broken Televison?

You could if you have a little knowledge on how to use a multimeter and are able to take the back off of your tv without extemely hurting yourself! There is alot of youtube videos out showing you how to repair alot of the broken televisions but is impossible to make a video showing every possible brand, model and scenerio with each set. What if you were able to fix your television over the web live via a webcam or chatroom would you? I am going to start my own business repairing televisions online via webcam or chat and guarantee to diagnose and fix it. I have been repairing televisions for over 30 years and I no with my knowledge I can repair any tv as long as the person has a webcam a multimeter and a little electronics background. I can diagnose it send you the parts you need to repair it and if it doesn’t then a free session will get another tech call. I can even have the power supply sent to me, repair it and send it back to you and step you through putting it all back together in any LCD, Plasma or LCD television. Contact me on facebook, twitter, email, or on one of my posts and I will respond.

I can not be responsible for any accidents that may result of my services. So don’t attempt this if you can not read a multimeter, have ever had anything electronic apart and no something about electronics. Don’t waste my time if the screen is busted as they are not worth repair!

Fix Your Own Broken Television

I have been in Television Repair for almost 33 years now! It’s not like it used to be back in the day, how many times have you heard that? ( Back in the Day ) You used to have to get out your big magnifying glass, schematics, test equipment, big bright light and alot of patience to troubleshoot Televisions. Troubleshooting them down to component level, down to that transistor, resistor, capacitor, doide, regulator, etc. and repair the problem. Alot of times it took an oscilliscope to trace the Video or Audio going through different circuits to troubleshoot and repair, align different parameters and so forth.. With all the LCD, Plasma, DLP, and Projector Televisions out today times have changed and quick! The Digital Boom changed everything, I haven’t had to use my oscilliscope to troubleshoot a TV in a long time. Anymore all you need is a Multimeter maybe a schematic on rare occassions and a little no how to troubleshoot Televisions and fix them yourself. Most of the Power Supply Boards in all new TV’s are marked with the voltages. Most people can check Voltages with a Multimeter and troubleshoot from there. Alot of people set at home and repair there own computers so you should be able to check for a few Votages and replace a Board. You don’t need that little component, most repairs are Board replacement to repair, unless you have 33 years of experience like me and can still replace down to the componenet level as long as I can still get the component I need. There are only about four to five different boards in a Television. There are alot of replacement Boards available through different distributors and some listed for sale on Ebay as well. All you need to no is the Model number and Brand of Television that it is and you can find Boards anywhere. Most local repair shops charge a Bench Fee to check out a broken TV anywhere from $50.00 to $100.00 plus parts to repair the Set. The average repair could run from $350.00 to $500.00 or more! Most people just throw it in the trash at that point and go buy a new TV. It’s getting to be a throw away world. I could actually have a Broken LCD Television shipped to me anywhere in the world repair it and ship it back cheaper than a local repair shop would charge you. I run a local Repair Shop in my hometown of Chillicothe, Ohio and charge a $35.00 Bench Fee plus whatever the parts are going to cost with very little markup. The average LCD Television repair out of my shop runs around $125.00 on 26″ to 32″ Televisons and about $225.00 to $300.00 on 40″ and bigger tv’s. If you do the math and check your local UPS for rates, you could ship a broken Television to my shop in Ohio for about $40.00 the average set weighing about 25-30 pounds. Plus the repair cost at worst $250.00 plus shipping is only $265.00. I can almost guarantee to beat any repairmans cost even the local repair shop up the street. Television repair shops are also closing due to people repairing them thereself or just throwing them in the trash and buying new. I repair alot of LCD and Plasma televisons and can get plenty more life out of them them most are! I have alot of years of electronic experience to just about fix any television on the market today and am trying to find a way to convince people to repair them instead of throwing them out. Tell me what you think!

Electronic Crash Course

If you no how to use a multimeter and no how to test diodes, resistors, capacitor, inductors, and transfromers then your a little ahead of the game if not then I try to find a course to teach you basic electronics. Hands on is always the best way to learn something so I’d Suggest collecting broken electronics and appliances from your friends, relatives, the dump, garage sales and flea markets, etc. Start on those that have been written off – you will screw up at first, we all did. As times passes your batting average will improve. It may not happen overnight but it will happen if you apply yourself. There will be many relatively easy successes but the ‘tough dogs’ may make up for these triumphs. Don’t let them get to you – not everything can be repaired. Sometimes, the basic design is flawed or someone before you messed up royally. Troubleshooting is like being a detective but at least the device is generally not out to deceive you.

Experience will be your most useful companion.

If you go into the profession, you will obtain or have access to a variety of tech tips databases. These are an excellent investment where the saying: ‘time-is-money’ rules. However, to learn, you need to develop a general troubleshooting approach – a logical, methodical, method of narrowing down the problem. A tech tip database might suggest:Replace C536′ for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don’t have a service manual or schematic and your tech tip database doesn’t have an entry for your sick TV or DVD.

While schematics are nice, you won’t always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don’t see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.

Here are just a few basic listings and schematics.

Resistor Codes

Schematic Symbols

Dual Volatge Regulator

12 Volt 20 Amp Voltage
Regulator Circuit

I no it all looks so confusing been doing it for over 30 years now and it is always a learning curve! There are alot of online courses available and even some good books and guides.
