    the link took me to a site to purchase the service manual and the resistors look as though they will need to be soldered in

  • Gail White May 26, 2008

    I'm glad you have faith in my soldering abilities. Aslo there are no 3.3ohm 1/2 watt resistors listed. Only 3.9ohm 1/2 watt

Your convergence ICs need to be replaced. Please let me know the model number of your set and I will post the correct ICs for your model and where to get replacements that come with instructions on how to replace them.

    Your model uses the STK392-110 convergence ICs I would also get a couple of the 3.3ohm 1/2 watt resistor also just incase as that model will sometime burn on or two of the 3.3ohm when the ICs fail. This is an easy repair. Heres where you can get new ICs and resistors plus free instructions and online tech support by instant messageing.

    Yes they also sell the convergence ICs you need under the convergence IC section on the left side of the page. They do need yo be solderd but its basic soldering skills nothing technical at all really.

    They dont list all the resistors as the 1/2 watt ones are all the same price anytime I order I just send them an email first asking if they have the right resistor I need and they send an email right back indicating that they have placed the resistor I am looking for onto their front page. Try leaving them an email. they man the site 24hrs a day so they respond quickly.

I have a prjection tv that has a red color that doesnt line up and appears to be warped


Projection sets have two very common problems.

The first common problem is convergence


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,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...

*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

Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.

Unfortunately, the drop damaged the picture tube. There's a piece inside the tube called the shadow mask. It is supposed to make sure the 3 electron beams in the tube strike only their own colors, and it has been warped or shifted by the drop. There is no repair except to replace the picture tube.

It sounds like you have a warped shadow mask in your picture tube if your set uses a picture tube. A shadow mask is like a screen wire that lets the three color guns shoot electrons to their respective phosphor dot on the screen to produce the three primary colors which are mixed properly to produce the scene that is being shown. In other words you have a bad picture tube. Stargazer

Problem in Screen display


Hi, J ! You didn't say how old you set is, but to me it sounds like you may have a warped shadow mask in you picture tube. A shadow mask could be compared to a piece of screen wire. It's function is to make the electron "beams" from the three electron guns strike the proper phosphor dot to produce the proper color- red-green-or blue. If this is the case the picture tube would requie replacement. Stargazer
