It looks like there is a projector within the television. Would these convergences IC's be in this projector? This ghost like shadows would be like a yellowish shade that outlines one side of the images or letters. I Googled the convergence IC's on this blog but my symptoms are different. I don’t have the shaking, bending or multiple lines and the TV does not blink or shut down. Just this yellow like hew on the left side of the shape. There are so many setting located on the projector, I thought it may just need to be reset, but I don’t have any information for what the buttons actually do. I just want to make sure the IC's are the problem.

My TV was working fine then today the color went nuts, image is shaking, bending, ghost, and multiple lines are seen. After about 3 minutes, the power LED began to blink then the TV is shut off. Based on some of the postings, it seems like the problem is the convergence IC. I opened the back of the TV and saw STK392-110. I did a search on the net for the parts and found some IC with STK392-110 and some with STK392-110T.)

    Yes, The STK chips are the convergence IC's. They are 2 in number, and both will have to be replaced. They are located on the mainboard, attached to two huge heat sinks. Here is a good pictorial guide on how to replace them.
    Here's another:

    You can buy the STK's online from here:

    Hope that helps!

    PS - I would appreciate if you could revise the rating to either "Helpful" or "Fixya", as Thanks for Trying" is a negative feedback. Replacement of the STK's will definitely work (if done correctly) and I would probably get get a Fixya! under other circumstances, except that I cannot physically do the repairs myself.

    If are unsure how to do this, try to get a friend who knows
    this kinda stuff to do it for you, or get a qualified technician.

    Warning!!: If you do not have a background in
    electronics repair, or are inexperienced, get a qualified technician to do it
    for you.

    REMEMBER there are very dangerous voltages inside a TV
    that can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECT

My zenith sentry tv has a double image on the words that come on screen. The people are clear but all wording has double images

Double images are technically called Ghosts, occures due to the setting and direction on the antena. You have to reorient your antena, in such a way that Ghosts disappeares from your screen. The reson for this fault is not with the TV, as it gets a direct transmission signal, and a reflected signal of the same, reflected from near or far objects, like tall buldings, hills and so on. The signals, the orginal and the reflected, will be processed by the TVs internal ciiruit, and the first will appear as strong picture, followed by the second, a weak picture, will be seemed as an image of the first one, just on the right side [view point] of your TV.
You just adjust the position and height of your antena, looking the picture, where there is minimum Ghost level is. No other repair should be done to your TV, as it is perfect, and you just give it only direct signal path. OK.

Additional information is required for us to assist. Can you better describe what you mean by "poor image"? Are the colors separated? Is the picture out of focus? Are the colors wrong?

Please describe the picture or post a picture of the screen if you can.

Duplicate image in pink displays on the screen.

From your description, it sounds like an alignment problem. There are 3 LCD panels in the projector. Each one displays an exact duplicate image of the others except it's either red, green, or blue. Under normal conditions, the images precisely overlay one another so you get a sharp image. Due to age, heat, or vibration/shock(impact) it would appear that the red LCD panel has shifted a little, giving the "ghosting" effect. You'll have to have the unit repaired by a qualified tech. He'll have the special electronic equipment needed to align the panels properly. Before sending the unit in, try a reset in the menu. Sometimes, the projectors can shift the image electronically, using math algorithms which will try to auto-sharpen the display. Hope I was able to help!---Rick

Double images with red halo outlines

Sounds like your describing convergence ICs. They cost about 10.00 each and you will need to replace both of them. And possibly the resistors that power them total cost under 30 dollars if you do he soldering yourself. Hope this helps.
