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 comturns blue and has shadows - 2c07611.png.

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.

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.

Horizontal blue lines with a slight blue wash in the screen


Hi,
Its because of Over Voltage of Screen (G2) to Blue CRT.
Take off front lower cover (speaker grill) and unscrew board. There you will need to find Focus Block mounted having 6 control knobs. 3 knobs are for Focus control and 3 are for Screen volts control. Find Blue Screen control knob and turn is Counter Click Wise slightly until bluish shade disappear on screen including few blue horizontal lines.
If you select AV input to adjust that will be fine as you do not need to wait for dark-scene.

Philips Blue Shadowing


If you have not already done so go into the picture menu and set the convergence. The convergence is the angle at which the three picture tubes meat at a given distance. The tv will have at least 3 and up to 64 convergence points, and those 64 can be set for all three colors. This can be tiresome but I'll be it will solve your problem. What your trying to do is get the color in the cross-hair so you cannot see the color behind the target. On top of the fine setting for each point and color you will probably have 3 gross adujustments for blue and green and maybe red. These adjustments will affect positioning, like what you are discribing. You should do this at least every month, the thermal cycleing of the lamps is what will cause this to creep out of adjustment.

Don't recommend replacing the light tunnel if you never had any experience with DLP optical systems. you need to pay careful attention to the way you remove any screws or you will be forced disassembling the engine multiple time to get the alignment correctly.
