Zenith R60v26 has burnt resistor at RK5 on convergence board


Hello, I have the exact same issue with my R49W36, I replaced the convergence chips but there are also two 1 ohm resistors with the same color pattern as yours that are bad. I have looked all over and cannot find a 1 ohm resistor anywhere. Where did you find it?

Mitsubishi - cannot converge 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,Panasonic2_bing.gif,Akai,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

Zenith 46" with a "hour-glass" picture.


If the hour glass figure is a seperation of colors that appear to be convegence mis aligned, then, the convergence ICs would be the problem. If the picture is clear and you have a bending on the sides then the pincusion circuit in the horizontal circuit is where to look. Be careful of this circuit, it does control the high voltage. The only way to have a board checked is to have an Authorized Service Center look at it. It does, however, sound like there is a cold solder joint in the power supply that has gradually opened up and now is permanantly open. Call Zenith (LG) to see who they recommend.

Converge


If the menu does not work, your problem is most likely a defective R3243 (110k 1/2watt) located near horizontal yoke connectors. Otherwise check the convergence module 9-1690, for open 1 ohm resistors. Located near large heat sink.
