Today most people have or are looking to purchase an LCD TV. The technology has taken over the market and even the new “LED” TVs are just the same type of TVs with LED back or side lighting (excluding OLED TVs) as apposed to the traditional CCFL back lighting that most LCD TVs use and have used for some time. When you take this fact and couple it with the fact that LCD TVs in general have about a 3-5 year life before needing some kind of repair, you can see how LCD TV repair is a very profitable business to be in. I know because I own a business that specializes in liquid crystal display TV and monitor repair along with other electronic devices. We not only have seen a huge increase in customers bringing in liquid crystal display TVs for repair, but also we have seen a large increase in the warranty work we do as well and all the extra work is for mostly LCD TVs along with some plasma, DLP TVs and more.
The fact that many LCD TVs under warranty are failing tells me I will most likely be seeing a lot of these same brands of TVs later on out of warranty as well. You may hear some people saying “TVs are not worth repairing anymore”, this is absolutely absurd, is it not worth it when on a daily basis I fix $1200 dollar TVs for $200 dollars and make $170 profit in 2 hours? Is it not worth it when I fix a $400 dollar TV for $100 dollars with $90 profit in 1 hour? No way! It’s worth it to the customer and to me. The secret is you have to actually know what you are doing and not just be a “board swapper”, if you are a board swapper then you most likely will not fix a lot of TVs because it will not be worth it for the customer to have the TV fixed for the cost of the board plus your time. You need to learn how the TV works and learn to troubleshoot the PCBs within the TV at the component level, then this can be an extremely profitable business and will be for years to come.
I would say that the majority of the problems I see with most liquid crystal display TVs are failures relating to the PSU (power supply unit) or SMPS (switched mode power supply) board. Many times the failure symptoms will not even seem like the failure is related to the SMPS board even though it is, for instance artifacts in the video or an all white display, dim display etc. these failures and many others (that are obvious SMPS problems) like no power or intermittent shutdown can be caused by electrolytic capacitors in the PSU that have an increased ESR (Equivalent Series Resistance) due to electrolyte venting out of the capacitor when it is hot and or chemical changes that happen to the electrolyte over time that cause an increase in ESR. Often times the failed capacitors will have a greatly reduced capacitance value as well. Of course this is only an example of some of the common failures I see with these types of TVs.
To learn more you can read my book “Troubleshooting & Repairing LCD TVs”, http://preher-tech.com/lcdtvrepairguide.aspx, or if you want to find a quick fix for your liquid crystal display TV check out my other book ” LCD TV Repair Case Histories”, http://preher-tech.com/lcdtvrepaircasehistories.aspx. I hope you will repair many TVs and electronics devices in general. Remember you can always email john@preher-tech.com with all your electronics questions.
