How to go in service mode for tv sony kp-46wt500.i did change the stk ic,the convergence is good in the midle but bad on the side

Did you replace the pico fuses on the G board there are two and usually one will blow when the old ICs fail and just replaceing the two ICs on the D board will usually not fix the issue untill the two pico fuses are checked and the blown one is replaced.

Im seeing duble words,how can i fix it?

There should be a convergence adjustment on this set. It will have a "cross hair" type pattern
You adjust the beams so that the cross hairs turn white. I believe Green is not adjustable intentionally. The procedure is to adjust the vertical Red line until it alligns with the Green line. Then adjust the vertical Blue line until it lines up with the Red and Green. The line should turn White.
Repeat the procedure for the horizontal lines. When you return to regular viewing mode the double
images should be greatly reduced or eliminated..
Hope I've helped you,
Best Regards,

Dubled up image and out lined in red

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Ultrascan hitachi 43" hd tv

What you're describing is convergence and the amps need to be replaced... IK04 and Ik05 are two STK392-110 and Hitachi suggests replacing them with the STK392-150's for greater reliability..
If you're not too capable in electronics this is one to leave for the professionals. But at least you can call around and ask what each shop charges for replacing the convergence amps in this unit...
Hope this helps.

65wp94 / broke glass

It's the display screen. The 65v glass mirror is inside the cabinet that reflects the image onto the screen. I think what you want is the front display screen....... and a leather belt.
