Hi


Thanks for using FixYa. Assuming this as a projection TV, the issue is with the convergence ICs going bad and needs to be replaced. It’s not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you’ll have to open the back of the unit and then replace the ICs(STK ICs) which are located behind the black heat sink and also check the resistors as if they are short the ICs might blow again after sometime. There are repair kits available which includes repair instructions with the parts, if you want to do it yourself you can buy and repair it yourself.Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

My Tv has red light (color) out of focus..I've tried tuning the lance but it's not the problem in the lance..it's something else..don't know what..do you?


Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here http://www.mitsubishi-tv.com/support.html

Philips 9P6040C 60 in. Rear projection


Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.
 
Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem. 

Here are some of the most common symptoms.
  • Screen looks 3D
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed in but stationary.
Solution:

You need to replace the convergence chips and convergence resistors. Check the site http://www.TvRepairKits.com . They have put together a kit for your exact model. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. 

Hope this helps,

Pictue is dark as hell


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
