    Hi Joe,

    Thanks! I checked on the pioneer parts website and they suggest a replacement part STK392-180. I found another thread that suggests this part is an improvement since it is a higher rated part and runs cooler. Any idea where I can buy parts other than Pioneer. They want $50 each!

    Thanks,

    DF210

The image color on projection is not the same as shown in laptop. There's is no red color.


It could be a broken connection in the computer lead for the red signal, or a fault on the projector that the red panel doesn't work any more.

To diagnose, bring up the projector's on screen display. If there's white in the menus then the problem is the cable. Replace it with a new one. If the menus are affected too then it's a projector problem. This requires the attention of a service engionner.

Cannot adjust color


Have you turned the controls from one of the presets? Presets are Vivid, Movie, etc. Most sets have to be in Custom or Customize to adjust the controls, likely on-screen with one of contrast, brightness, color, or tint selected. If those are horizontal bars then up/down selects which and right/left select decrease/increase or red/green for tint. Start with 50% if no reset (0% for R/G) or start with the non-Vivid settings. Consult AVS forums for you model to get better settings. Rules of thumb: Brightness should be as dark as possible without losing gray scale at lowest part. Contrast should not be so high that whites bloom or make it hard to see. Color should not blow out any color nor be unnatural. Tint is best judged on flesh tones. -Ken

Here is something that may help from the toshiba.com website under your model number television. Q. Why are people on my screen green?
Models: 32HL17, 37HL17, 42HL17, 42HL167, 47HL167, 52HL167, 42HL167, 42LX177, 46LX177, 52LX177, 57LX177
REF:FAQLCD00107
If the problem is not the connections, try adjusting the tint on your television. A high tint setting will usually create a green
image on the screen where as a low tint will create a more red hue. In order to access your television's tint:
1. Press the “MENU” button on your remote control and use the LEFT or RIGHT arrow keys and select the
VIDEO menu.
2. Then use the UP and DOWN arrow keys to highlight PICTURE SETTINGS and press the "ENTER" button on
your remote.
3. Next use the UP and DOWN arrow keys to highlight TINT then use the LEFT or RIGHT arrow keys to adjust the
TINT. If the picture is too green the tint will need to be lowered.
4. Once you have adjusted the tint to your liking, use the DOWN arrow key to highlight DONE and press ENTER. The toshiba customer service telephone number is : 1-800-631-3811. I hope this helps you with your problem.

You may have 1 of two problems.

1) Convergence Chips are failing - Using your original remote goto the "convergence" screen. 

Try to adjust the red - UP - DOWN - LEFT - RIGHT

Next try to adjust the blue - UP - DOWN - LEFT - RIGHT

If you can move both colors in all directions you do not have a convergence issue. 

If you can't move one or more colors in one or more directions the convergence chips are defective and need to be replaced. 

If your convergence chips test out ok the most likely problem is......

2) CRT Coolant is cloudy  - The bright outline you described is one common symptom. Other symptoms include dull images, red or orange tint, halo around images.   

If you goto the site www.TvRepairKits.com - and click on "Tips" - you will find more detailed instructions on how to check the convergence.

Your TV most likely has one of two 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 them in all directions 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 images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Hello paulaspec,

You have a problem with the three factors, and they are screen voltage, focus voltage, and control (focus 2) voltage. Basically these voltages have to be adjusted since the components in this section have aged some. These controls are usually located in the television on the IHVT (Integrated High Voltage Transformer) or as it is also called the flyback transformer. these controls must be adjusted together, along with the color controls. Here is how the adjustment is done (You will need a schematic diagram, a DC volt meter, and a color bar generator to do these measurments):

 

1) turn color and tint fully counter clockwise until you have a black and white picture.

 

2) connect the color bar generator to the TV (ch 3) and turn it on, you should see bars in various shades of gray

 

3) adjust as best as possible the color and tint controls to obtain the color bars on the screen Red Green Blue.

 

4) measure the voltages on the focus, screen and control grids of the CRT and match them to the schematic digram measurements.

 

5) adjust the focus screen and control grids to match the ones on the schematic diagram

 

6) once this is done then you adjust the color controls once again to obtain the red green and blue bars on the TV screen.

 

This should help if the CRT (picture tube) electron guns are still good and if the flyback transformer voltage supply is working.

 

However if you do not have a background in electronics please take the TV to a shop for repairs.

 

I hope this helps,

Thank you,

First adjust the contrast level 25 percent.Now see there is any improvement. If the performance is well there is a problem in video section. May be capacitor leakage like 180v supply filter, and coupling capacitor in video section.
