Philips Projection Screen TV Model PTV915 Horizontal Alignment

Hello everyone, 
I have a Philips Projection Screen TV Model PTV915 with Horizontal Alignment issues. (for some reason this forum system does not recognize the model)
The RED is not aligned and I do not know where the focusing controls are on this unit.
I opened the unit up and tried to work the RGB focus dials and I have focused them to appear sharp and clear but the I see 2 distinct lines of text each within the color space. 
You can see The text frozen on the screen and a red layer of text floating just above it to make it appear as a red duplicate behind it.
How do I align them? I assume there must be some sort of control within the unit. I have already tried to use the RGB focus dials but it is does not align them.
Any help you can provide would be much appreciated.

    You have a problem with your convergence circuit. Most likely the convergence IC's and resistors need to be replaced.

Problem solved, needed to get the universal remote i was using set up with the proper code. Once I did that I was able to use the remote to set up the single & multi-zone Red & Blue Alignment.  I also pulled the back plate off and manually adjusted the RGB focus knobs. It seems to be working just fine now.
Thanks to all the other posts.

Hello linda, hi, I dont think the remote or manual can help the color issue problem, the tv needs to be looked at by a qualified technician. If the TV is a tube type, there are magnets on the neck that needs alignment, this alignment is done while the TV is ON. so high voltage risk are likely. keep out and call service.

hello dm beatty, First i must ask if you have anything placed on top of the tv? second what i would suggest is for a professional repairman to come and fix it. There are proceedures which you may do it yourself but if you were to mess up it would cost you a new tv. If you would like more assistance to do it yourself place post again and i will be happy to assist.
Please post what you do and how you did it. I look forward to your posts.
