Today I decided to fix the tilted picture on my Panasonic CT-27SX11 TV. I took the back off, adjusted the yoke so that the picture would be straight. Then I had difficulty getting the case back together. Finally I did and proceeded to turn the set on. The picture was extremely dark and I could not see the setup menu, because all the boxes were black, No text was present or I could not see it, If could get into the menu or reset the set somehow, I'd be in business. Unless I disturbed something when I took it apart. Help!! Please help!!

You're discussing about the width problem to picture. If yoke have a short in between its wingdings [even a single winding short], will cause the failure of horizontal output transistor. As per you report here, the set has a raster, but problem is with the picture width. There possibliliites for this fault are. 1. Lack of voltage from the SMPS power supply output. 2. Horizontal width capacitor. 3. Horizontal output capacitor. Check the output voltage from the SMPS section first, and confirm that it is OK.
Its an easy adjustment but it requires you to work around the deflection yoke on the neck of the picture tube. Above the yoke is a red connector that is carrying 30,000 volts then on the yoke itself you have wires that are connected to the horizontal and vertical circuits that can carry up to a 1200 volt pulse. So this alignment is not for anyone but a technician. I personally would leave the tilt until you can have a technician touch it up for you. Take a moment to rate my answer. Thanks...
Hope you have fixed this problem by now, if that tv is unserviced, I mean if nobody has ever opened it, it could be a problem with the positioning of your tv, just tilt the tv in different positions and find out the position in which it will show the right fit. If it is serviced, especially yoke is changed, this is rare, it could be because the position of yoke is not aligned properly.
