Over past few day my picture is loosing focus and showing green after a while being on after powering off a while its fine but issue returns

It could be several things but I'd start with a main board, the fact its shutting off kind of drives me away from Tcon as that shouldn't shut the set down if there was an issue there, it also could be power supply, you could test the voltages from the board once it starts giving issues and if some are off then change the power board.

what is the model number? is it a plasma? lcd? crt projection?

the problem in the main power supply it depends of the kind of faillure but normaly to repair it not very expensive
good luck

You have a projection light element out. I had the green element go on mine. I had a service agreement so a repair tech changed it.

As the others said, there are the two settings. I had a similar problem, then realized how it worked. You need to not press very hard while it focuses first. Then you can press all the way down, if you hold it all the way down, it doesn't recognize that you've already passed the first "Focus" pressure point and gone into the second "Capture" pressure point.

I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.

The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).

I regret to tell you that he is probably right. The problem is the trinitron picture tube. Sony advertised it with such high esteem for years and wouldn't doubt that they would do that. The phospher is burned out in the tube and the guns (red, green and blue) are weak and the focus electrobes in the tube are also weak although Sony made it a lot different that any other tube requiring extra circuitry. There is no fix for this. If you could bypass the blacking out you would still have the bad out of focus picture problem

I have a blue-ish yellow ghost tint which just appeared on my 51" 51SWX20B made July 2002. Did the magic focus got a number 5 at the end. Did you get a number when you did the magic focus?

The writing is more blurry than the picture. it is not that serious while shifting 1 focus wire might be loose. 2 crt base loose. 3 dust like thing near focus wire. 4 adjust focus control fitted on eht. caution it is high voltage portion do not touch unless you know about it.call tech to do it. good luck.

Hello, the problem with your projection TV is in the so called bad soldering in the vertical deflection stage. Please contact a pro in order fot fix the error. If you need more assistance please advice. Arpi
