Hi,
Problem seems with convergence output section and there would be dry solder connections in convergence output section.
Re-soldering convergence output chips pins will be helpful to solve this issue.
If you have no experience of soldering work in tv circuit board then local tv repairman will help you.
Let me know if you have additional question.
Thanks.

I have a 2 year old LG LCD TV (model 42LG60) and I am having problems with the screen. I turn it on and everything is fine for a few minutes and then the screen goes to red or green lines that are fuzzy....


Not really a solution, sorry, but I've got the very same problem. I haven't noticed the time before tv faults, but nontheless, it greenscreens or like in your case, redscreens as well. I've been told to open the back, which I did to check the status of the capicitors, which I've done. But, the capacitors "seem" fine. No bulging or popped tops. So, I'm at a stand still...not sure what to do at this point. If someone gives you solution, I sure would appreciate your forwarding it on to me. Thanks. Robert

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.
 
Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem. 

Here are some of the most common symptoms.
  • Screen looks 3D
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed in but stationary.
Solution:

You need to replace the convergence chips and convergence resistors. Check the site http://www.TvRepairKits.com . They have put together a kit for your exact model. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. 

Hope this helps,

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Screen blank


use the towell trick! Wrap the 360 in 2 towells turn on and leave running for 15 minutes. It gets very hot but after the 15 minutes turn off the console and power it back on again and it should work. Dont know if this is a permanent fix but my 360 hasnt broken again so far. Dont ask me how but it works, google it if you like. It also cures the 3 red lights problem.

Picture fuzzy


I would suggest to unplug the tv from the wall for about 15 minutes and then plug it back in,and turn it on,this should reset the microprocessor and realign the colors back to normal.let Us know how it goes and if you need more help.
