Lower screen is pinkish


The screen's backlight is dying. Sooner or later this screen will be pinkish and later it will be darker and black. You need to replace the whole screen (it is not easy to replace the backlight).

MY LAPTOP WONT GO ON AND THE BATTERY HAS A PINKISH LIGHT


The battery has a pinkish light or the laptop screen has a pinkish light? When the screen has a red or pinkish tint to it, and is black still, it is the LCD inverter that is the problem. The computer and the LCD screen work fine but you need to change the inverter. It happens very often and you can find inverters for your specific laptop online and certainly on eBay.

White has turned pinkish


sounds like the linear adjustment is out of whack.....most projection type tvs, projection, lcd, plasma, have to be correctly aligned so that the color grids overlap each other to properly display the correct hue being created. you'd need the service code to re-adjust it, or have it serviced. also possible that one of the color grids is bad, but if you have all three (red,blue,green) colors showing on the entire screen area i would doubt it

3-d looking picture on top and bottom of screen


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 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.
