EEVblog guy fixes Panasonic Viera plasma TV with black tape!

Facebooktwittergoogle_plusredditpinterestlinkedinmail

(Note: This isn’t an actual repair video)
Here’s a little fun video created by the David L. Jones of the EEVBlog.com, a video blogger who tackles topics in electronics engineering and other related stuff. He thought it was a great strategy to get a top-of-the-line Panasonic Viera plasma flat screen thinking that it’s going to give him years and years of perfect service. Well, needless to say he found out how wrong he was when, after 2 or so years of light use, his unit started exhibiting the dreaded vertical black line/column and thin white stripes problem. He was told that the plasma screen needed replacement but he suspects that it’s just a simple column driver ribbon/cable problem that plasma screen televisions are quite notorious for. But alas, the TV was designed such that you won’t be able to fix the ribbon as it’s permanently embedded to the plasma screen module. The ribbon can’t be fixed or replaced. Dave’s gripes about his experience with the Panasonic Viera is quite entertaining to watch along with some commentary on its impressive engineering design (which, as he pointed out, didn’t do him any good). Um, and see how he fixed the problem with the use of black tape!

Commonly Reported Vizio TV Problems

Facebooktwittergoogle_plusredditpinterestlinkedinmail

vizio_logo_ratings_box_logoTechnology has no doubt come a long way over the years and continues to advance rapidly. Of course, it is far from perfect and there are a number of things that can go wrong with any given household appliance or gadget. There are some very impressive televisions on the market these days. Vizio, for example, offers an array of LCD, LED, and plasma models in all sizes. Any of these common Vizio TV problems may arise at any time throughout the life of the set.

Perhaps the most common complaint regarding Vizio TVs is the appearance of a blank black screen even when the set is switched on and the indicator light is glowing. The screen may still light up in some instances, but in either case the screen remains blank. This issue is usually corrected by replacing the power board, but there are several other things that could be the culprit, like the backlight converter, the T-con board, or even just a faulty screen itself. If a repair shop does not have all of the LCD TV parts that could possibly be causing the problem readily available, they may need to order them all in order to single out the guilty part, which can get rather pricey.

Faulty remotes are another common issue. This is one of the much easier and inexpensive Vizio TV problems to fix. Usually this is due to a bad IR sensor or a loose wire and the parts can generally be found online for less than 20 bucks. If the cause is unknown, just replacing the remote altogether is also fairly easy and of course less expensive than dealing with a problem with the TV itself.

Commonly reported Vizio TV problems also include sound-related issues. This may be a matter of faulty speakers or disconnected wires, which are both easily remedied. If it is an issue with the main unit, then it will be a little more difficult and expensive to fix.

There are many shops offering LCD TV repair services. Purchasing an extended warranty is usually advised to cover the cost of potential expensive repairs and replacements but you will need to rely on your judgment on whether the price of the extended warranty will truly be worth it (most of them are quite pricey).

15″ Magnavox LCD Repair Tips for Model 15MF170V/17

Facebooktwittergoogle_plusredditpinterestlinkedinmail


Here’s another video of a LCD TV repair made on a Magnavox 15MF170V/17 which is a small 15-inch flat panel TV. The malfunction is characterized by a blank white screen when you power up the unit. There is audio coming out but the screen is just white and not displaying any pictures.

The repair video showed that this problem is being caused by the absence of electrical input which is needed to power the electronics of the LCD screen such that all you are seeing is the LCD backlight which is white.

The problem was traced back to a faulty MOSFET (metal-oxide-semiconductor field-effect transistor) which is a very small 8-pin chip that acts like a switch that allows electricity to be fed to the LCD electronics.

The fix involved replacing the MOSFET but it does not show the actual process of removing and then replacing it with a new one so this is not beginners stuff. The transistor is very small and the video even said that it is a bit tricky to work on without the appropriate tools.

Important thing is to determine first whether you are having the same problem by checking if the LCD is really not getting any power using a digital multimeter on the connector pins that was pointed out in the video.

If you need the schematics for this product, you may check out another post of mine that discusses where you can possibly find LCD repair manuals and other relevant data sheets for the needed parts.

As always, handling electronics is an activity not to be taken lightly. Be sure to take all the necessary precautions. If you are a beginner, it is recommended that you take an LCD Repair Course first.

52-Inch Samsung LCD TV Repair Video for Fixing Power-up Failure

Facebooktwittergoogle_plusredditpinterestlinkedinmail

Here is another video showing a step-by-step procedure on how to fix a Samsung 52” LCD TV having some power issues, which I am seeing is one of the most common issues people encounter after a while of using their flat screens. This is actually a very similar to the Polaroid LCD TV problem I posted about a while back.

This problem is characterized by the failure of the unit to turn on. Trying it a number of times might eventually do it but if you leave it as is and not do anything to fix the problem, it may get worse and stop turning on altogether.

Like the Polaroid TV problem in my previous post, the problem can be traced to capacitors gone bad and the video will show you how to get to them safely and replace them using very simple tools, one of which is a soldering iron. Operative word here is “safely” so if you are in doubt whether you can do this due to safety concerns, I’d suggest you just bring it to a professional.

This fix can also be performed on other Samsung models in the same line like the LN46A750 46” LCD TV and will cost you just around $15. You will definitely get charged more than that if you have it done at a repair shop.

As usual, if you are interested to learn more about how to repair LCD TVs, I’d recommend checking out this LCD TV repair course by Kent Liew.

Below is the 2-part video of the repair:

How to repair a Polaroid LCD TV that’s showing no pictures

Learn How to Repair Other LCD TVs Besides Polaroids! CLICK

For those who bought a Polaroid LCD HDTV some two or so years ago, chances are you’re already having some issues right now with your unit. These televisions, particularly this model (FLM-3732), are notorious for blinking out on you because of some bad capacitors. Basically the symptoms would be such that when you turn it on, the blue indicator light lights up but the screen pictures do not. It’s just blank like it’s turned off. Although I’ve told people that this year might be the best time to buy a new TV, I remain practical in the sense that if you can repair your malfunctioning TV and it won’t cost you more than $4.00, then definitely, repairing should be an option worth trying. The alternative, which is to go out and spend around $600.00 for a new LCD TV should remain a course of action in the event that your $4.00 repair attempt fails.

Plasma and LCD TV Repair Information: How easy is it to find them?

Facebooktwittergoogle_plusredditpinterestlinkedinmail

If you’ve been scouring the internet for information on DIY television repair then you probably already know that it’s one of those things that are easier said than done. Sure there are lots of sites and TV repair forums that offer help on the subject but most of them offer bits and pieces of information that will be hard to put together most especially if you’re a non-technical person who’s looking to undertake a do-it-yourself repair project.

Of course you want to do it right and avoid mistakes that could cost you more. Hence, you set out to arm yourself with as much as information as possible so you go on the internet to search for them but finds puzzle pieces. Yikes.

We all know how it goes. You go to a forum and post a question and waits for an answer. If you’re lucky you get an answer quickly and one that actually helps. If you’re out of luck, days and months will pass while your plea for help gets stuck in virtual limbo. This poor fella waited one year for an answer to his plasma screen problem query. He probably gave up on it and just hauled the thing to a service center and got billed $600 for a problem that can probably be resolved with a careful soldering exercise. Or worse, he could have thrown the television out. Hopefully, he didn’t hurt his back carrying the thing out and thereby spent thousands more for physical therapy.

Looking for repair manuals and schematics? You will find online stores that are selling them per copy but if you wish to get more for many other brands and models then it will definitely be expensive. But there are these LCD TV training membership site and plasma TV training membership site that are offering repair manuals for over 400 brands and models worldwide for a small fee that would be equivalent to just around 4-5 manuals if you get them from those buy-per-copy sites.

Yes, you could get some manuals free as well but again, they will merely be pieces of the puzzle. The membership sites I mentioned above are actually giving out a free service manual for Sony LCD TV Model KLV-27HR3 and one for LG Plasma TV Model DU-42PY10X. I downloaded them but alas- I didn’t know what to do with them. If you’re a non-technical person like me, you’ll probably need more than just the TV repair manuals.

The two membership sites that I mentioned above have them all— basic information for beginners and detailed technical data for seasoned or experienced repair gurus. And here’s the kicker: They have visual troubleshooting guides which I definitely love!

They’re the ultimate repair forums where you won’t have to buy each and every manual. You pay a one-time fee equivalent to to a couple or so decent burgers and you will get all the information you need from, get this, from only one or two sites! You will also get access to new manuals and information that come out any time in the future!

See there’s no need to go sleuthing all over the internet for a wild goose chase. Get complete TV repair information now and quick!
