Question about Projection Televisions

1 Answer

Power light flashes 3 times

You suggested a convergence ic stock number 392-110. Is this easy to install or difficult. I am very handy with cars but lack any real knowledge in the way of electronics. What should I pay for someone to install. It appears to be a 20.00 part.

Thank you.

Depending on your model you will most likely need two. most people will want to charge about 400 to 600 dollars sad but true. if you know someone that can solder and de-solder, that will be your best bet. A repair shop will charge alot and it takes an experienced person about 40 minutes , a novice maybe an hour but its actually a easy repair if you can solder.

Blinking power light


Hi,
Power light blink 3 times shows that convergence out ICs got defective and need to be replaced.
If you are handy with electronics stuff repair and can solder parts in circuit board with proper tools then replace two big black ICs, convergence out, mounted on aluminum heat sink.
Or call local tech to fix it.
Let me know if you have additional question.
Thanks.

I have a JVC AV-56Wp74 Blue power light on the front keeps blinking and the screen is black & makes a popping sound


There are a couple of common problems this model has--one is easy to confirm.


How handy are you if I tell you to disconnect the convergence board to see if it is your problem?

The blinking blue light means the set is in protective shutdown, and I know a fairly easy way to see if it is your problem and how to fix the set if it is.

Let me know if you need help--I am here to help people and l know a lot about this set.

Powers on for about 5 seconds and shuts off with 3 flashes of the power light. Continues to flash 3 times.


Hi: Three flashes for the power indicator indicates convergence failure, Most failures are the large black convergence IC's on the convergence board, have these replace to restore operation, The Part number should be on the chips themselves. But just in case the part number of the are STK-392-110, Replace them with 120 for extra life expectancy. (STK-392-120)

JVC- red wave on screen and letters doubled


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

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Shuts off then flashes power light


I think this is a power problem, check the power supply for bulging or leaking electrolytic capacitors or other damaged components.
