Question about Projection Televisions

1 Answer

I have an older model PioneerProjection Monitor Receiver (model Pro-119). I have been experiencing color convergence problems that until recently was able to solve by using the owners manual's adjusting guide. The red, green, and blue crosses are so far off that the remote control is unable to line them back-up completely. Any suggestions?

If you have a cable box, unplug the tv and cable box from wall for 1 minutes, then plug both back in. This should solve your problem. It worked for mine.

Help with RCA projection TV P46812BL (chasis ptk195AA)


You have probably blown one of the convergence ICs. Effectively the easiest thing to do is replacing the whole convergence board, so that no soldering is involved.

Here you can buy a replacement convergence board, just select your model.

Let me know if you need further help.

I'm experiencing different colors on the tv when displaying an image.


If these colors appear to be like a 3-D image, the problem is in the convergence circuit. Please update this with the make and model and I will provide you with further information and instructions.

Thanks,
Dan

I have a older model


You will need to replace both convergence ICs. This is a simple common repair for all projection TVs. If you would like I can post a link where you can order your ICs and they provide step by step instructions on how to remove the old and install the new ones.

Convergence problem, lower left corner fixed green gun convergence bows upward


You have a componet out of tolerance in the green drive circuits, resistor or capacitor. If you have the service manual you should be able to take some raedings off the test points for the circuit and be able to track it down. I am enclosing a link where you can purchase the service manual for that set for 10.99. They will mail it to you unless you go back to the site and request that they email it to you by clicking on the contact us link. They also offer unlimited free support if you purchase your manual. I am one of their support techs. Hope this helps. Heres the link

Red, bule, green lines do not line up together.


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.
