Here's what Philips FAQ says about your convergence procedure:
Question How do I adjust convergence (align colors)? Answer Note: For best results, the Projection TV needs to be turned on for 15 minutes or longer before adjusting the picture tubes (convergence).

Press the INTELLISENSE button on the remote (under the flap). During the convergence process DO NOT press the INTELLISENSE button again and DO NOT move the Projection TV.

So, I think you're going to need to order a replacement remote.
search "replacement remote" at http://www.philips.com

normally when something like this happens, we could right away propose what can be done, in your case, since youve already changed a lot of parts on that tv, you can at anytime fix it. the tv alone is not fixed yet as of the moment but to some it up, experts have already given you some ideas on how to fix the tv. cheers. hope youll fix that tv in no time.

If you are having "shadowing", this indicates a convergence problem in the LCD optical engine. Convergence is the correct alignment of all panels so there is no shadowing, or at worst limited to a one pixel shift. Some models can be adjusted, others cannot depending on the optical engine.

They adjust FOCUS and Screen settings---they have nothing to do with convergence---if you have not touched them---do not---they are not real easy to reset correctly.

What is wrong with the set and what is the model number?

let me know and I will try to assist you

hello it sound like convergance chips may be the problem

Manufactures sometimes contract with other tv companies to build their tv. Regardless of the internal hardware you still have a philips tv. I beleive this set was made by Hitachi. And what you are looking for is a replacement board. This board is referred to as the small signal module. When contacting a rebuilt board, have the model# and the chassis# available. And contact PTSELECTRONICS.com or Andrews Electronics.com. The board you seek is in the rear lefthand side on the floor of the TV. You will see a pair of tall aluminum fins. Theses are the heatsinks for the convergence ICs. I would definitely replace this small signal module, as repair on the local level will require pulling the board in and out of the tv several times. The company will give a part number and then you may order this. Striving for success the first time!!!!

Hi there!
You would need the manual to adjust the convergence. First to correct the curving and then to line up the colours. Not too sure wether you need a service remote or the one that came with the set. If no adjustment takes place when you adjust, replace the Convergence Amp IC'S. Good luck,JUS004

Requires convergence amp IC replacement ( two) and check
resistors in vicinity of IC's....fairly technical repair....Please read
some of my convergence solutions and let me know if you want
step by step instructions............................T.

You probably have a problem with your convergence board. Try resetting the convergence manually on your TV - go to Philips website for instructions on doing this if you have lost the Quick Start Guide. If the manual convergence fails, then your convergence board needs to repaired or replaced.

because you have defective convergence correction circuit amplifier! the only thing you can do now is to replace the convergence IC.
