Does this happen when using all input sources? Did you try DVD or something to see if problem persists? Do you notice any buzzing sound when this problem occurs? Please provide this info so that i can help you with your problem.

    Ok. The there is no problem with the deflection ICs. In such a case I would check the caps around HOT(horizontal output transistor). Do you see any that have swollen tops or cracks(or tiny holes) at the top. you do then you are gonna have to replace them with those of same specs. Not recommended that you do it yourself if you do not have prior experience in handling electronics. The caps hold dangerous voltages for several days after being turned off. They have to be safely discharged before you start working on the board.

    Can you help me find the HOT? I'm an electrician and I do have a general knowledge about circuit boards but I have not openned the back of the TV yet. I will be doing that tomorrow and hopefully any bad caps will be easiby seen.

    Sure I can. Just send me a high res pic(upload it on imageshack.us and get me the link to the image) and I will mark the hot for you. Even better if you can get me the images of the caps so that I can mark the ones that I think are faulty.

Color red seems to be more prominant...than other


I've had this problem with my projection TV recently. I would say your lens/lamp is to blame. It might be time to change it, depends on the last time it was changed, most of the time, the TV will tell you that it needs to be changed, but not always. I think your best bet is the TV lamp.

I think you need to have the transmission filter changed, and right away. If that doesn't solve the problem, then have it tested at the transmission shop. Rick

Picture won't come in clear until TV "warms up" for 15 minutes or more


Change the capacitors first per the instructions in the link below. Symptoms could be anything from high-pitched hum to no picture at all. On these defective models, I would start at the caps and work back. It won't hurt to replace them anyway.

Tv go thru different functions on its own after being on for a few minutes.


after it warms up, and starts your problem. turn tv off. unplugg it. then feel the tops off all the caps for heat. also check the hv wires for leak and fluid leakage on boards. could be a possible broken trace or cracks in solder. possible in signal board.

Mag innovision LT716s monitor


When I turn on my computer the monitor takes a long time to warm up and colors change and vertical lines flash across the screen from right to left before the screen becomes normal again. Now the power light even goes out upon turning on my computer and I have to unplug the video cord and plug it back in to start the screen back up which even takes longer.

Green and magenta colors offset in picture


Sounds like convergence problems, set may have been moved lately and this can cause it. Did you try Magic Focus when the set was warm or did you try it when you just turn on? Set needs to be warm, before you try it. If nothing works you will need convergence kit
