There is no convergence. try resetting the settings to factory default through the menu. if you have a dlp, the colorwheel and dmd chip are set. if you have an lcd, the lcd panels are locked down. if they are off, you'll need to go inside and realign them physically. but that's chore, because you have to plug it in, turn it on, see which way you need to go, power down, unplug, remove the top cas, remove the main board, adjust, tighten, replace the board, replace the top, plug in, power up, check the image, and do this as manny times as necessary. leave it to the service centers.

You dont it is only an Engineer who can do this as it is very dangerouse due to UV output from the unit when alignment is done.

Seems the rgb is note centered getting 3 ghosts


This is a convergence problem that will require factory service. Convergence adjustments must be made with particular test images and tools to access the internal adjustments. This is not a DIY repair.

I have a problem with the colors not converging properly.


reset the settings to factory default. the resolution may be off. if the resolution matches and you still have trouble, the lcd panels need physical realignment. only a sharp service center can/should do this. try av solutions in ny. they're really good. www.avsolutionsny.com

Bad convergence. do i need remote to converge unit? i can bring up menu and make those adj's by set top buttons. but i have three misaligned pic's


there is no convergence for these. the lcd panels are fixed. if they are out of alignment, you'll need to replace the entire optical engine. first reset the settings to factory default. see if that helps.

How do I ADJ the convergence on my PTL555U projector?


These adjustments are internal to the machine, It is not a recommended user adjustment. Typically these are set at the factory under controlled conditions using a known signal source. Also, I'm not 100% sure about your model (I'll investigate further), but it may not be adjustable at all. How far out does the convergence appear to be? Can you see it under normal use conditions or only when using the test pattern?

Thanks,
Dan

Video adjustment on LCD projector


convergence on lcd is a tough issue... you can if you are really good and know what you are doing adjust the panels to correct some convergence issues. but depending on how many hours the unit has, the LCD panels may have warped due to the heat inside the projector, then corrections is pretty impossible.

there is no convergence on this animal. reset the settings to factory default and set the resolution to match the source. if the colors are way off, you need to adjust the mirrors manually, which is quite an undertaking, and would not recoment doing it yourself.
