Re: How do I adjust the picture to fill the screen
I was having problems in the tv menu getting full screen. no matter
what i did there was two black bars on each side of the screen. i have
att u verse so i went into the cable menu to options. In the options
tab i went down to system options then to aspect ratio. in this screen
you get a few options like 4:3 standard definition and 1080i on high
def screen. I chose 1080i high def and then played with the zoom
function on my remote and the problem was solved. hope this helps

It looks like you are saying standard definition pictures do not cover the screen like HD pictures do. Standard def is formatted 4:3 and high def is 16:9. They are not the same so your high def screen is made to display the not as tall but wider high def picture. In order to fill the screen with the taller and not as wide 4:3 aspect ratio std def picture you must tell the TV to stretch the picture or otherwise fill the screen.The TV will have controls you can exercise for this purpose and you can set it up to always show std def in a particular manner. The alternative, if you want the standard Def picture to look true to form, is to view standard def in Letter Box form. It's appearance will then include black panels on the sides of the picture. So the problem is not with the TV but in accepting older format pictures playing on newer format displays (TVs.)
Plasma tvs are tricky for picture. They use two boards to burn the plamsa gas instead of one (LCD)...This almost doubles the price for any replacement boards, unless you know componenet level repair.
Overall, if you can find someone that will work cheap and knows what they are doing...then yes it isn't the most intence repair...but if NOT...then it's probalby too expensive to buy the replacement baords.
if you see the volumn bar on the screen when you adjust the sound then the tv should be OK. So look for HDMI wire not inserted fully or what ever wire sends your info to the tv from your cable box, satelite box, or whatever. Or does anything show at all on the screen that you can see, like snow on antenna without a signal input. Maybe a real problem.
To answer part of your question;
Whitout having the complete story on your tv and what prompted you to replace the Ymain and drivers along with the Zsustain.
I would suggest that you look on the back panel, you will see a sticker with voltages written on it.
For a 50" plasma set it should be somewhere around 195 to 205 volts for the VS voltage.
There is a control in the power supply circuit to adjust that voltage that usually can be measured on one of the fuse of the Ysus or Zsus.
You can also vary that control slowly while you look at the screen and you will see a difference(sparkles) in the picture.
It might just be what is missing now to repair your set.
Good luck and don`t forget; this is a freebie so you can either say thank you for the advice but no thank you or just thank you :)
This is know as the" Blue Haze" defect. A tech may try to lower the screen voltages for you. Realign Ve, 110volts to 100volts. Vset from 195volts to 188volts...and the Vs from 197volts to 190volts. This was an authorized fix early in 2007. But more importantly you will have to live with this, as replacing the plasma screen is very costly. You probably have a bad screen.....SORRY!!!!!!
The noise reduction option will cause a blur on fast movement. Also, you probably already know this, but a standard definition broadcast will look very blurry on an HD TV, so make sure the channel you're watching is actually an HD channel.
Oh, wow, I just noticed that this is from October. Oh well, maybe you're still having problems.
Depending on what source you are using, this is possible. Most digital sources are set and cant be changed by the tv leaving black bars. Though video, svideo and component should allow multiple masking and cropping modes to strech the picture.
