Press the menu button, if the menu has green missing as well it's the tv. If you can't tell with the menu, use a second source, being a dvd or a gaming system. If the green is still missing make sure you use different cables, it will be the tv. if only one source is the issue it will be the source that is missing the green color.

I have a Sony KDF-E50A10 Grand WEGA LCD. The picture cuts in and out and the green standby light flashes. One expert said the STKs need to be replaced??? How can I do this...please advise in detail.


Replace your lamp. Your DLP set does not have Stk ic's in it. I don't know what expert told you that but I can assure you he has never worked on a TV. You can purchase the lamp from www.dlplamps.com

I NEED THREE LAMPS THE RED GREEN AND BLUE. MY TV COLORS ARE OFF


No you just need to install a convergence repair kit. Your model uses the Sony type 1 convergence repair kit available from www.tvrepairworld.com the kit contains the parts and the CD with detailed instructions.

I'm having a problem with the color green being distorted on my TV. Is this a color tube issue, bulb issue, lamp issue?


This is a picture tube type TV. No lamp.
You don't describe the distortion.
A colour green picture that is twisted and shifted away from the other colours is a convergence problem. see Projection TV Convergence on this site.
If the green is smeared, out of focus, larger than the other colours like a halo around objects, things like that, it is the green picture tube. Sony has discontinued most of the picture tubes so you may not be able to get this fixed.

Large blue blob in middle of screen on my 42" sony tv model # KDFE42A10


check to see if your green and red lamps are lighting. if they are not then go to your convergence board and check to see if you are getting the right voltages. the voltages are written on the circuit board on some tv's. i believe that you are having problems with your convergence.

Converging green?


jaymz, you can`t move the green, the green tube is always mounted in the middle and is not adjustable from the convergence menu. red & blue should be converged one at a time on top of the green, once you have accomplished this the crosshatch grid will be white and that means your done :)

JVC MODEL # AV-48WP74 48 IN. BIGSCREEN TV.


I had a problem with my TV colors not lining up. One day I turned it on and the green was out of wack. I checked this message board and replaced the STK chips, bad soldering and all led to me just giving up on that and buying a whole new Convergence Board ($185). I just plugged this in and though now my Green lines up okay, my red is out of whack. Is there something I am doing wrong? Can anyone help me? Did i miss a step? Frustrated......Bruce
