Hi, unfortunately it sound like your television has a problem with the backlight system, it is either the backlighting bulbs or the power supply that runs them. It may be possible to reset the televisions brightness setting by keeping it unplugged for a day. Having lower brightness setting may " let " tv resume operation. other wise it'll need repairing. I hope this was of some help, Good luck, Prodzilla

My 46 inch Dynex TV show half of the picture screen and the other half is scrambled what could it be


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Samsung 46 inch lcd no picture only sound


Could be backlight or the Invertor. While the sound is operating shine a flashlight into the screen and see if you can see the picture or not then let me know and I will assist you. But I will also need the model number of the set.

Cannot get closed captioning turned off on my 46 inch dynex lcd. The setting is off, yet still have closed captioning


Try the basic "re-boot" most digital devices respond to - pull their AC supply plug out for 10 minutes, reconnect, re-setup if asked to and problem may well have been sorted.

Rca 46 inch lcd tv, no sound


Go into the menu and change the HDMI Audio settings - the manual will give you a breakdown on this. HDMI is a little glitchy - if you were using red/gree/blue cables before switching to HDMI, you might want to consider going back to them - just an opinion.
