There is a problem with the board of your television.That problem is in vertical section, theres a leak capacitor at the vertical section of the board.Its better to replace all the leak capacitor to make the picture back to normal appearance.If you can't do the repair or replacement of of capacitor try,Call a repair technician to do the repair or troubleshooting..Thanks..

Could be power supply but most likely sustain boards, which are very expensive to repair. Consider replacing with an LCD with warranty!

Need s to be replaced the main board.

When the screen goes completely black, shine a very bright flashlight closely at the screen. If you can see the image, then the most likely problem is that the backlight inverter has failed.

The inverter is a circuit board that works like a flourescent light ballast. If the inverter fails, there is no backlight, and the screen is black.

Since the invertor is a high-voltage component, I would also listen for any unusual sounds associated with the failure: e.g. buzzing, whistling, popping.

To rule out some sort of connection failure, see if you can recreate the failure mode when using the TVs internal setup menu. The setup menu does not rely on any external inputs....of course neither does the volume control or channel indicator on the screen.

check option bites find it on crt or back cover to enter serv mode coll following comands
062596 menu or display the data will appear select options and set by vol and ch keys

you have to go to the setup for the TV audio and change it to audio out, not speakers.

you need to replace y-sustain board.

If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.
