my 37" xenius tv started losing its picture to a stripe screen then started flashing red blue green .know wont come on at all .wht part do i need to fix it please
It sounds like the LCD panel is badly damaged, if that is the case, it will not be worth it, sceen is the most expensive part of the whole TV, you may be able to sell each parts of the TV on EBAY. Post the pictures of the screen will help.

Hi, how is the cable box hooked up to the TV? Is it HDMI cable or componet (red/green/blue) ? When you say totally green, do you mean the the picture is only green with the other colors missing or every color looks green ?
Resetting the TV If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:
NOTE: Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time. 1.

Plug the TV power cord back into the power outlet and turn on the TV. 5. Open the on-screen menu to confirm that the TV is responding again. 6. Turn off the TV and reconnect the devices. 7.

This is a power supply problem. Try to check the fuses ,fusable resistor ,capacitor and transistor in power supply board.
