Our replacement samsung dlp tv lamp doesn't give us a full screen picture on any stations other than the High Definition stations, how do we fix this?


The high def stations are full screen as they are transmitted in a 16:9 ratio which is full screen. However the non HD channels are transmitted in a 4:3 ratio which is square and not full screen. Usually this can be rectifyed by putting your tv in 16:9 mode through it's menu's. You can also adjust this setting through your cable box if you are using one.

Hope this helps

Toshiba 57H82 convergence problems. TouchFocus


See my solution <http://www.fixya.com/support/t2795690-convergence_off_blue_line_only_vertical>.
You need to get to the service menu--it's been 4 years so go to AVSforum.com to turn off the different guns and get the better pattern.
At your risk: To get into Service mode:
1. Turn your TV on. 2. For X81 or earlier series: Press MUTE on your remote and release. 2. For H80/H81/HX81 series: Press MUTE on your remote and release two times ("Mute" on-screen) 3. Press down MUTE on your remote again and hold. While holding, press the MENU button on your TV set's front panel. 4. Release both buttons. 5. An "S" should appear on your screen. Press MENU again on your TV. 6. Now you're in service mode. Channel Up/Dn - Scrolls through Parameters and Volume Up/Dn - Changes Parameter Value
To get into convergence mode:
Get into Service mode, then Hit '7' to bring up the convergence grid. Buttons 100, 0, and ENT control which gun you want to turn off (if you want to align the red to the green without seeing the blue gun and other variations). 2=up, 8=down, 4=left, 6=right, 3=change gun to converge, 5=converge that point. To exit convergence mode you press 7 once and your screen should look like it's imploding then return to normal and then you press 7 to get back into regular service mode.
I have more info found on the board. -Ken

Cant see top 2" of program


Try going to the service mode. I think it goes like this. Press menu, and hold it. Then press volume up and volume down at the same time for 8 seconds. Then you should be able to go to service mode. scroll down till you find the adjustment for vertical size, the top part. If the service mode proceedure I gave you is wrong, You can try asking someone else here if they know how to go into service mode for your particular model.
