Re: Key on tv can't view anything only sound

Someone has locked out access to functions. Possible "parental key". Check menu settings for this. If user used a password, you will need it

Black and white picture with red lines vibrating with sound.

More info would be nice. Are you using HDMI or Component cables. If it is component cables (red, blue, green for video white and red for audio) Check your red and blue connection. Green alone will give you a black and white picture.
If you are using an HDMI cable, replace the cable to see if this changes anything or if you have another tv swap cables to see if problem stays with tv or moves to another tv.

Sony kds-60a2020 lamp problem

I would change the whole LAMP ASSEMBLY because if you touch the lamp while changing it out of the housing the oils on your hands will cause premature failure.Most of the time the lamp assembly's come with replacement instructions but yours is not too bad it is located on the left hand side if looking from behind set.

TV smokes when you turn it on and no picture

Check to see where the smoke is comming from, the far left side of the unit, it is probably the flyback/horizontal output transformer. The big gray/black thing on the board with the two red wires out of the top of it.Replace the horizontal output transistor (D2348) with a new one to increase reliability. It is the large three leged transistor to the left of the transformer. Use Sony parts if possible.

You can adjust the lines and make them straight. You can also in the same process, make them line up.
1. With the TV on, press the mute button the remote control so that you have picture but no sound.
2. With remote in one hand (holding it as far from the TV as you can but still be able to reach the TV with your other hand), press and hold the mute button again, with the other hand, using the control panel underneath the screen, press the menu button on the TV set.
You will notice an "S" on the screen on the right hand side about 2/3 from the left, halfway up the screen (If you did this right).
This means you are in service mode.
With the remote, curse right only once and you will have some information displayed in the upper left. The top line is Item, the one underneath is Data.
Press "7." This will display the built in cross hatch pattern. You can move the line around with the directional circle located at the center of the remote. Using the "3" button, you can decide which color to move. To move the curser to a new location, The number pad doubles as a direction key pad. (2-up), (4-left), (6-right), (8-down). To simplify the process, you can eliminate the red or blue or green lines and only focus on one color at a time. "0" will shut on/off the green line. "100 button" will shut on/off the red line. "CH RTN or Enter will shut on/off the blue line.
"7" will exit the process as well as get you there.
Power off when you are done and turn back on.
Repeat as needed.
