    You have been a great help. I have discovered that I can buy the convergence chip and cooling oil for $100+. Now I need to know how difficult is it to replace the chip and change the oil? How long would it take the average guy and how likely is it that he would be successful? Thanks!! Rick

Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move tmy hitachi 60SBX72B having picture convergence pro - 2c07611.pngdirections your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around my hitachi 60SBX72B having picture convergence pro - 578ba6c.jpg

Seems like the convergence chips are the problem. The picture with the bow in the center of top and bottom matches my screen. Also my colors don't line up.

Garage door light blinks but doesn't stay on


Three blinking lights & door won't close by Candi
(Winston-Salem, NC)
Garage door will not open and close with remotes. Three blinking lights occur when we try to close door. What does this mean? It is a Linear unit.

I will assume you mean that your garage door will open with your remote but will not close. It should close if you press and hold the wall control button until the door is fully closed.

If that is the case, the 3 blinking lights indicate that your garage door's infrared safety beams are not properly aligned.

1) Check that the operator has power. The green lights on the sender and receiver should be lit.

2) If the receiver's green light is on, but the red light is off, the receiver has power but is not detecting the infrared beam from the sender. The red light might flash when the beam is partially detected. This can be caused by
mis-alignment or something blocking the beam.

Adjust the safety beam sender and receiver while watching the receiver's red light (stay out of the beam while aligning it). When the red light stays on, the beam is aligned and your garage door should operate normally.

http://www.linearcorp.com/pdf/manuals/LCO75.pdf

NOTE: If the receiver's red light remains off, check for:

1) Dirt on the receiver's lens,

2) Sunlight shining into the receiver's lens,

3) A short in the safety beam wiring (from staples or at the operator terminals).

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

My Tv has red light (color) out of focus..I've tried tuning the lance but it's not the problem in the lance..it's something else..don't know what..do you?


Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here http://www.mitsubishi-tv.com/support.html

This sounds like some of the capacitors have burnt out! (does it stay in line then warm up and go out of line? or is it the other way around?) After 9 years there may be many more problems to come with this model TV Projection TVs have a much shorter life span then say a tube tv! (This could cost upwords of $700.00 to fix!)
Please rate this response to your question
Thank You!
