Question about Philips 43P8341 43" Rear Projection Television

2001 Philips 43P8341Blue outlines on images

Screen is darker than normal and most of the images are outlined with blue tint. Sometimes in the corner of the tv the color is normal, but still dark.
Then you have a strange color blue that is outlined on different areas of the tv. It sometimes pops in and out, at the top or the bottom. Very strange look.

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

You might consider changing the convergence chips. They do more than just adjust convergence in your set and they're pretty inexpensive.

The blue outline is a convergence problem. Depending on the brand of tv you have there are adjustments to fix that. If the adjustments wont work then the convergence circuit will have to be repaired.

You may have 1 of two problems.

1) Convergence Chips are failing - Using your original remote goto the "convergence" screen. 

Try to adjust the red - UP - DOWN - LEFT - RIGHT

Next try to adjust the blue - UP - DOWN - LEFT - RIGHT

If you can move both colors in all directions you do not have a convergence issue. 

If you can't move one or more colors in one or more directions the convergence chips are defective and need to be replaced. 

If your convergence chips test out ok the most likely problem is......

2) CRT Coolant is cloudy  - The bright outline you described is one common symptom. Other symptoms include dull images, red or orange tint, halo around images.   

If you goto the site www.TvRepairKits.com - and click on "Tips" - you will find more detailed instructions on how to check the convergence.

My screen has gotten much darker


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

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
