    thank you for your response, and the info. maybe im missing somthing?
    on plastic thingy i found two phillips adjusting screws , unnamed (no focus no screen) .. adjusted as you suggested, and picture was beautiful (no blinking) for about 3 minutes. i was soo excited wanted to wake up my wife. glad i didnt cuz blinking and washed out color returned as soon as i attempted to adjust picture thru t.v. menu...
    . I did like you said, adjusting bottom screw, when turned all the way right, shut tv off. when turned a little, bright pink... when too far to the left, no picture (black screeen). in between, no change except no longer seems to get brighter and then blink, it stays bright and blinks. top screw does not seem to affect anything???

Hello, I have a Sony KDS-55A2000 and it works fine for a couple of minutes and then it switches off and the green led starts blinking for about a minute and then the picture comes back and works fine


First thought would be the lamp may be about to fail if it has not been replaced in a long time---a warning will be the picture is a bit darker than before and takes longer to get bright than it once did.

No picture, black screen


Not a TV Technician, use the following information at your own risk. Two things you can do first: using the keys on the front of your set press and hold the menu button when while holding it down it goes from menu to channel listing press the adjust (<->) and channel up buttons simultaneously to get to the factory set up screen once there use the select button to scroll to next set up screens locate the contrast it should range from 1-63 find the one you like. Second: for the horizontal lines not to say that this is the solution there are two adjustment apparatuses inside the TV chassis if your familiar with taking the set apart and not getting shocked and hurt59274cc.jpg two dials on the fly back transformer ones for focus the other brightness you can try these fixes but I have to say again that you use at your own risk. I do hope though that the information is useful

PANASONIC 36" TAU --- NEED HELP


Sounds terminal. Companies build things with "planned obsolescence" in mind. In other words. You buy a TV today, and the warranty says it's good for 4 years. 4 years and 3 months later, it dies.

I hope someone else can help you.
Good Luck!

Picture blinks in and out every few seconds


The lines in the picture and the blinking makes me think maybe the digital / logic board is going bad.. you will need a tech to resolve this and it will be expensive.. In time you will loss the picture altogether as the board will get worse.

My Sony comes on then both sound and picture goes black.


After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

KDF-E55A20 is about 3 years old.
