The model indicated uses two STK-392-150 CHIPS OR 110 CHIPS.

It sounds like a convergence problem and I will attach two photos here of typical sets with this trouble. See if either look like your kind of problem and if so I can tell you what is needed to repair the set.

    I don't see anywhere on this post where the instructions are on how to fix the convergence problem. The bottom picture you supplied is exactly what our screen looks like except it's on both the top and bottom of the screen.

    My tv developed the problem as shown in the bottom picture last night. I'm fairly competent with electronic repairs if straight forward enough. What's the repair process and is the DIY route a substantial cost savings?

Ghosts


How old is ur tv...? Cos the wear & tear is the cause for this ghost appearance. The repair for this is only temporarily. It can not be eliminated completely.

Generally the blue ad yellow colour can be removed by a tool which is available with a tv technician. It is not very expensive to do this. Hoping to hear from you.

Thankyou

I replaced the main lamp 6 months ago. Now I have blue on the right, yellow in the middle and normal color on the left. I also have a ghost image of tree branches on the whole screen.


Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Found it here:http://www.discount-merchant.com/SONY-1-758-484-22-p/1180916.htm Have a blessed one!

Yellow, blue and green ghosting of picture. Convergence mode will not allow realignment of the red and blue lines


Hi,it sounds like a light engine problem.Lcd Technology uses 3 chips blue,green and red that create the image ,when they start to fail color discoloration will occur.If it's an Dlp pay attention to sounds of buzzing,whirling and high pitch sounds because it could be your colro wheel.

Color convergence problem


If you follow the instructions on the other thread, you should be able to resolve the problem. Try the simple stuff first. Resolder the pins of the convergence ICs and see if that alone resolves the problem. Sometimes that is all it takes.

Keep us posted.

Hitachi 50" Ultravision too much yellow, not much blue


First of all sorry for delay.
can you provide a image of yello shadow.I believe it seems to be technically say "ghost image"
If it is ghost image we can try by entering SERVICE Menu and adjust RGB level of the light engine.

Good luck
