Have you done the two year technicians course?

Here is a question that we see often.

Question:
I've replaced everything in my television because it previously had a black screen with no lighting. Now it doesn't turn on at all and all I have is audio. What could be the cause ?
So your television stops working properly and you think it must be easy to fix, because you can buy boards on eBay, and you can watch YouTube videos. So you make a decision, you buy a board and you fit it, but the television still doesn't work! This is a classic case of the 'let's try replacing this' method of television repair and illustrates why it is a bad idea. It doesn't work for a number of reasons. To correctly diagnose issues, you need to know every board, what is does and every component on the board. You need to know which part has failed, replace the component, or replace the board. The parts you purchased off eBay were probably out of scrapped sets and not tested. The part your put in was dead when you put it in, so you just moved on to another guess at what might be the cause and replace a board that is fine. And so it goes on, you change all the boards and it still doesn't work. Did you notice the large print that says 'No Refunds, NO Returns'. This is to stop you sending your old one back and saying it didn't work, but the unscrupulous use it as an excuse to get money for selling items that may not work! The course to be a television engineer is 2 years full time education, take it to someone that knows how to diagnose and fix. It is by far the cheapest option. The part that failed might be a 20 cents fuse diode hard soldered to a board. They will charge you $2 parts and an hours labour.

If the entire screen is curved, and it is not taking the whole screen, then you have a vertical deflection problem.

If the colors are double and do not match, with lines of different colors around pictures , then you have a convergence problem, often caused by a faulty convergence board.

The curving effect can be a side effect of bad convergence, or you may have both problems at once.

Unless you are a TV repairer yourself, better calling technical support. Usually you can ring the number listed on the owner manual.

SOURCE: picture is bending at the top and bottom and looks 3d

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

Vizio tv screen went gray


Hi Mike,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Vizio Plasma HDTV not working, flashing static!


I would start looking for a new set, replacement parts for that set are pricey. Trust me, I just recycled a P50HDTV10A that had a busted screen. I couldn't believe what the parts sold for !!! I don't know your preference LCD or PLASMA, but prices have really come down. So if it's in you budget, treat yourself to a new TV !!! Whatever you do, don't just toss the old set in the trash, toss that puppy on Craigslist and If you can get $50-$70 for it, take the money and run !!!
