You have a convergece board failure. Changing one board will not nescessarily fix it. It is recommended to change all 3 boards in the unit. many try this as a DIY and fall afoul because it is a specialist job to retune and reset the paramaters. The cost then becomes greater than if a tech did it correctly the first time. Be advised it is not a simple DIY.It requires soldering and desoldering skills, specialised tools and a knowledge of circuit diagrams.

    Ronald It would only be a guess, as i am in Australia and costs differ But generally from others that have commented it costs $300 in parts in USA + labour But generally having it done for you is a better investment from the stats on this forum Best wishes dennis

The TV is showing everything in a 3D kind of way. Everthing looks like a 3D proection, with only red and blue overlapping at some points.


Try to use a convergence function found in the menu. If that doesn't work clean the lenses with alcohol and q-tips. Good luck.

Hi there, this is what we call in the industry convergence board failure. this board regulate the rgb and keeps everything in order so the picture looks nice and clean. when this board starts to malfunction, what you are witnessing is usually the result. I suggest repairing this convergence board. this will fix the 3-d effect.

Red color border on the pitchures


Probably the convergence output integrated circuit is at fault. There are two-one for red and one for blue. They should both be changed. Also, sometimes the resistors feeding the I.C. may have opened as well.

Philips 60 rear projection hdtv looks 3D


If your red convergence controls will not remove the red in all four directions, you have a faulty convergence IC. You will need to replace both. They cost around ten dollars each. Let me know if you need anything further.
