Some models require two buttons to be pressed together for menu access - usually at the bottom or side.

SOURCE: Correct overscan on kv-34xbr800

With TV off, enter the following on your remote:
Display > 5 > Volume + > Power now you are in service mode 2 & 5 will take you up and down categories 1 & 4 will take you up and down settings within categories 3 & 6 will change the data up or down
So press 2 until you come to the 2170D_2 category Press 1 until you get to HSIZ and change the data down to the required setting (different data registers for different width settings)
It could be more involved but this might do the trick in your case. Good luck!

the picture tube is gone.
i repaired 150 sony xbr and kv series with that problem.sony has a single gun not three and has a great pix,but burn out faster.
there is a main screen control that you can adjust ,but the tube is gone.
on the back of the crt there is 3 gun drives r g b .
turn the color all the way down so it is black and white.
if there is a green ore purple tint,one gun is out of balance.
ajdusting the r g b controls so that black and white is normal is what you want to do.
the crt board has the screen bias voltage 800volts on it so be very careful and use an insulated screwdriver to adjust the drive controls.

Sony Trinitron KV-32S40 32" TV problem


This is a simple and common problem. The solder joints on the vertical output IC have cracked loose. I actually did a housecall on the exact same set with the exact same symptoms this morning! A good tech will resolder the pins of the vertical output IC and all other major solder joints on the main board and the set will play fine.

Check first for bad solder on the vertical IC, Im not sure for your set as I do not have the service manual, but it may be location IC301. If after resoldering it does not fix it you may have to replace it and you should replace the electrolytic capacitors in the vertical section. Hope this helps. Don

Screen went dark


Sounds like the screen control which is usually mounted in your high voltage transformer (Flyback) has opened up. Stargazer

Picture problem


Usually that symptom is caused by cracked solder joints on the vertical output IC. As the IC starts heating up, the picture starts breaking up at the top with several "dancing" dark lines appearing, the top scrunches down and then when the vertical quits altogether, the screen goes completely black. A good slap on the side of the TV might make it happen faster or clear it up temporarily. If you have experience working on PC boards then you can resolder the pins of the vertical output IC but if you have never soldered parts on PC boards then allow a qualified tech to handle it for you.

video card went out in the tv. You are saying you need a schematic. Be real careful getting into tvs. They have very large capacitating capacitators in them that can electrocute you. You need to take it to a repair specialist and have them run a check on it. Sounds like the video card to me though.

Picture takes hours to appear


Spounds like the b+ feed filter capacitor off the flyback that supplys voltage to the three drive transistors on the crt board is bad.
