After replacing the color wheel and lamp in my Samsung HLP 5063W DLP, the projected image is mis-aligned with fixed screen (down / left). On attempting to realign, I managed to put the image slightly out of focus. Now the picture is out of alignment and fuzzy. What components affect alignment, and how do I adjust both these characteristics back to original quality?

Re: projection image mis-aligned & out of focus
To align picture in DLP TV, you should know where and in what order 3 LCDs are fixed and on top of Light engine there are Hex Screws for alignment of each LCD. I can provide you few illustrated pictures of light engine to give you an idea about alignment. A professional TV tech can perform alignment properly.

Do you have three flashing lights on the front? You most likely have a problem with your lamp or color wheel. Those two component combined are pretty much the guts of your TV. If you are handy, you can replace those parts yourself. I have a 50" Samsung DLP and I've already replaced those to items myself. Otherwise, you can contact Samsung at 1-800-SAMSUNG and they can assist.
I bought my parts using Amazon, had them shipped to me, and took an afternoon to take about the back of the TV; documenting everything and taking photos of the progress, until it was done. There may be video tutorials on Youtube. There was for my model (HLS5086). Here is a great link to help you along. Good luck. http://blog.trebacz.com/2011/01/50-samsung-dlp-hl-p5063w-with-3.html
Hi it sounds like the problem is with the convergenge ics these can be replaced but the problem usually comes from a bad resistor this causing the ic to go.
The only problem is without having the proper testing equipment in front of you you could keep guessing and never find the problem the best thing to do is if you dont have the equipment nor the knowledge of diagnosing the problem it is best left to somebody who know what they are looking for.
I see this problem often on these sites and it all comes down to the convergence ic failing they usuall fail to a resistor failing on the main board the board will need testing and tracing back from the ics to eliminate any resistors that could have failed.
I have seen alot of people that have replaced the ics without checking the resistors and then they have the same problem shortly after.
The resistors tend to start failing shortly after the warranty has run out.
The cheapest sollution would be for you to take the tell yourself to repair shop as calling somebody out might charge for the call out and for transporting the tell.
Their isnt much you can do yourself but if you need it i can get the spec sheet for you so you can follow circuit diagrammes let me know what you want to do
If the capacitor on the ballast was puffed up or blown up you have to replace the lamp, ballast & SMPS at the same time. But if the ballast is not trying to fire the lamp it sounds like the color wheel is not coming up to speed. If this is the case, the set will not turn on.
In some cases,after installing a new color wheel, the speed of the wheel motor must be adjusted to obtain proper speed to ensure a satisfactory image. Unfortunately, you can not and should not attempt to do this adjustment yourself as the service menu contains many adjustments which if accidentily mis-adjusted may cause irrepairable harm to your TV. Ask a local samsung servicer to do an "index delay" adjustment in the service menu.
As part of the power up sequence on the Samsung HLP-4336W the lamp isn't turned until timing pulses are detected from the color wheel. The color wheel motor is powered through the flat brown four conductor ribbon cable and the timing pulses are detected over the the three conductor ribbon table.
