Screen Adjust


You can't. There are no adjustments for height and width. Not all programs were shot on 16 x 9 wide screen resolution so it will leave the screen with black spaces . around the edges. Nothing wrong with the TV, and nothing you can do other than the zoom buttons you use now.

What is cost of yoke for panasonic ct tv?


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.

I have 2 black spaces on each side of my screen


The width of the picture is less than normal. It can be adjusted by entering in to its service menu options. But, entering service menu options and adjusting data values there is a skilled task. It will be best to contact any expereinced service techinician ot do this. Or Visit the site named 'Electro-help' for more details. Check this link and select the site. View it in 'Flip card' option, which can be selected from the drop down box menu at the left top corner or the display window. It will make search easy. If you are confident that you can do this, just proceed. If not, do not tamper the TV.

I would go with it. The 1/8" on each side you are worried about can probably be trimmed if need be. The manufacturer is usually very precise on an measurements they publish.

Check very carefully for cold solders on horiz. drive transformer also replace the electrolytic cap that shapes the horiz. drive signal - if you have a scope and manual compare the drive signal shape.
Some times using poor after market horiz o/p's also causes the problem - does the o/p heatsink get to hot to touch or does the horiz o/p blow immeadiatly?
