Recently noticed a green ghosting to the left, but only on one AV channel.
The channel is 'AV3' which I use for an Xbox 360, the ghosting is noticable on the sets own menus which to my mind rules out Xbox/cabling issues, but correct me if I'm wrong.
Switch to a different channel and bring up the sets menu's and no ghosting.
Using component video connections into the AV3 connections on the rear, running at 1080i, have tested switching Xbox output to 480p but still the same ghosting.
The set has no convergance options in the menus - I believe by design as they are not mentioned in the user guide.

Re: Convergance issue on one AV input only
This is not a convergence problem in the traditional sense as it would effect all inputs not just one. I would be looking at the video switching IC as the defective part. I'll look up your model to try to get you more details. Are you going to attempt the repair yourself?

Your TV is out of convergance. You'll probably noticed that there are red, green, and blue images. You'll need to determine if the problem is in the power supply or the convergance board. Usually, the convergance amps go bad and opens resistors. Do you know how to read a schematic and use a multimeter? You will also need to know how to remove the old parts and solder the new parts into the circuit board.
Odds are real good that the cooling fluid in the green and blue picture tube assemblies has become contaminated. You can tell by looking down into the lenses with a flash light. Funny thing is the red never gets contaminated because whatever organism is causing the problem can't survive in red light. BTW this may still not solve all of your convergence problems but when the colors are so badly diffused the convergence sensors for flash focus can't lock onto the beam landing.
Well this is the fix for the usual Ghosting problem....
To bring up the "service" menu, put the TV in standby mode, then press in sequence :
Onscreen Display ( the little screen with the i+ in it ) 5 ( channel number 5 ) Volume Up ( upper end of volume button ) Analogue ( middle top button )
The TV should switch on and when it's warmed up, you should see a screen with lots of big green lettering on it.
Press the "menu" button ( middle bottom )
Use the direction dial to move down to "LCD Drivers" and press right on the dial to enter this menu.
Move down to "S H Pos Reg R". It should be "10", change it to "11". ( Left/Right to adjust ) Move down to "S H Pos Reg G". It should be "10", change it to "11". Move down to "SHPos Reg B". It should be "10", change it to "11".
Press the menu bottom to drop out of the menus, and the standy button to drop to standby. Switch back on, and hopefully your ghosting will be gone
hope this works
hi there, if you are familiar with electronics you can do this :adjust voltage at hight voltage block it has screen and focus written on it and comes from flyback transformer,but be careful cause it can be to dangerous if you touch something else,ah,ah adjust only the one that says screen and has a R on top,that means red,ok,thanks.
Sounds like a convergence amp failure. Depending on model, there may be 1 or 2 large Ics. Due to the delicate soldering involved, a tech should change these amps.Often the old part numbers have been upgraded, and small value resistors may need to be changed also.
sounds like the high voltage transformer arc or one of the picture tubes arc causing the convergance ic to go bad you can try to replace the IC heres a site to help: http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm
