Occasionally, I'll be playing my PS3 or have my computer hooked up to my Dynex LCD HDTV and the screen will just start randomly flashing solid black and white vertical lines. Sometimes it will be once and stop, other times it will happen constantly for as much as an hour. It is the TV as the HDMI cable works fine on my other LCD. Any way this can be fixed or can anyone at least tell me what this could be?
Vertical lines in the display indicate a failing screen. New screens are expensive and not worth the labor and parts charges to repair it. It's new monitor time.

Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck
SOURCE: TV does not always recognize the DVD player
that's a firmware problem where your tv's firmware does not handshake with your dvd's firmware. This could be from your dvd's software being to old for your tv to understand it. HDMI (TDMS Technology) still has Alot of catching up too do with 3rd generation tv's. Alot of HDMI devices still have the first gen software loaded into them. So a tv after 2005 won't work with HDMI from 2003 (1st gen). Most tv's made after 2007 have software that's "backward compatible" so they will work with first gen HDMI.
How does your tv perform outside this problem???

Your correct, LCD's don't burn. This sounds like a defective main control module. I would take it in as soon as possible to have it looked at.

I hope 3.5mm to twin phono would have plugged in headphone jack of PC to get sound for TV, right?
Reduce PC volume level up to zero and increase it very little bit to get sound in TV.
TV is getting excessive sound level from headphone jack and causing mute circuit to activate to avoid any internal damage.
Testimonial: "Good advice, but didn't work. :("
. Go into the service menu (Press, then release the INPUT button on the remote, then key in 2580). Scroll down to "Other Settings", then go to "EEPROM Init", then press enter, select YES and press enter. This will reset the TV to the factory defaults. If that does not work, send it back for repair. Good luck!
