    I have the same problem with my 60" Philips Magnavox Flat screen (9P6040C102) My blue will not line up from left and right. Also, the color seems very bright. Is this the same problem? If so, please give some help.

    Your model uses two STK392-120 Convergence ICs and you will also need about four 6.8 ohm 1watt resistor. The following link has the ICs and resistors and they will provide free insatalation instructions with pictures and free online tech support when you do the repair in case you have any questions during the repair.

    Heres the link.

Shadow images and scrolling banner curves upward and back down.


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.

Samsung HCM5525W TV red blue outlines on images


The Samsung has bad convergence IC's most likly. This should be repair ONLY by a trained technician as a TV set is not a place to experiment or tinker with because of the extremly high voltage inside. This repair should cost you in the range of 250 to 400 bucks . Good Luck
