Blue lines that surround a face or broken lines across the screen

These lines can be best seen on light clothing and faces.This happens when the TV is in vivid mode. The only way to make them disapper is to select cinema mode which is a darker picture or lower the brightness. This is a Panasonic rear projection lcd tv. Appears to be the same problem that the Sony Wega rear projection TV has.

Your TV most likely has one of two possible problems.

Problem #1 - Failure in the convergence circuits. ( 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 are some photos of convergence problems.

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.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, 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.

Check the voltages that comes to the back light inverter, especially, the voltage from the main digital board that controls the brightness. If is found OK, be sure that the backlight inverter board is faulty. If not, the main baord. If you wish to get some details, check the site linked here. Pull up older posts.

Green hazy lines across my projection tv screen


The coolant in between the CRT face and the focus lens has probably become discolored and would need to be drained, cleaned and refilled. The green CRT is the center one and it would have to be romoved in order to refill it.

My Phaser 6120 leaves light lines across the face


Lift out imaging unit and look down and back toward you, may need flash light, and you will see a 5" x 1/2" piece of glass. Carefully wipe it with soft cloth. Toner gets on this glass and creates the streaks. Often means a bad toner cartridge is leaking toner. Ron

Samsung LN-S4692D - Vertical lines (>15) & static on screen


this sounds like a scan board gone ,, if you check ebay youll see two things,
1, other tvs for sale with the same fault (It might give you a clue to the fault ie , which board )
2, the same tv as yours with a broken screen ,

i dont know how good you are with taking things to bits but i personally would buy the tv with the broken screen and start swapping over the internal boards ?

Have you checked your home insurance policy for broken tv,s
it may have fell of its stand when you were'nt looking?
