When I first turn on the set, you get a good picture. Then in about 1 minute, vertical lines appear on the screen covering the enitre screen. I have had the back off the set. Nothing appears to be burnt Lots of IC chips. No caps that I can see. ????
What is the brand and model number (not indicated here) so I may try to give you an informed answer.
that is fine---if the lines etc are uniform all over the screen likely the main or digital board bad---if just one side or top or bottom may be an inverter board(some use two boards and some a large board for both sides.
If a limited number of lines as described could be inverter or even a bad panel--lines usually black in that case but not always.

can i get a manual for this tv, the blue is out of alighnment
SOURCE: Circle Vertical IC please on picture
I've cropped out most of the picture so it would fit here. The vertical output IC is I601. It's circled in the picture below:
If you can't place it from this part of your image, it's on the heatsink just above and to the left of the horizontal output transformer, which has the high-voltage lead running to the picture tube. Resolder the IC connections and that will probably take care of your trouble.

Hi. it is not a standard TV. It is a Maxent LCD TV. M# MX-26X3.
Yes, the screen has even lines, top to bottom, all across, side ti side. Sometimes it will flicker very erratically.
Does this TV have "caps" ? I didn't see any when I had the back off of it. Are they hidden? I did notice there are a lot of pc boards.
