Black and white picture, then color, need to warm up?

My LG 37" LCD turns on in black and white. after 20 minutes of so if you turn the tv off and then on, it comes on in color. why should an expensive tv need to warm up? one other thing, when the picture is black and white (for regular channels during the first 20 minutes of bad picture) the high def channels come in in color. i know its not my cable connection too. thats what the dummo's at the lg costomer service line said. its still under warrenty. anyone heard of a similar problem?

If it is still under warranty, go out and take it to the repair shop now! this could turn out to be an expensive repair if ou have to pay for it. Your problem is the digital board with the tuner on it or the processor board for the signals, like the video and such. This could need the entire boards as most maunfacturers do not supply too many repair parts for these sets. Good Luck

Color problems vizio lcd hdtv

If your tv has a custom settings area, first turn all color down on set so picture looks black and white. Now in color settings look for red blue and green color bars. Use the bars until the picture looks as true to black and white as possible. Also, try changing color temp.

Horizontal lines shadowed / blured picture after 20-30 minutes

There are some semiconductors or capacitors that are leaky. Might need thorough check up inside the TV.

No picture -- white screen -- no sound

With no video and the the colored stripes, it sounds like the LVDS cable needs to be reconnected to the LCD control board or the control board itself is bad. If the unit is only 3-4 months old, it should be covered by warranty

Lg 32lc2r, only showing picture in black and white

Make sure that the color control level is set to the default or 50% to start with. This should be in the Video menu.

The colour for the tuner and for the encoded base-band video uses a circuit area called the colour demodulator. It is possible that this cirucuit area has failed and needs servicing.

The TV should be under warranty. Send back. Sounds like the panel is faulty (half the value of the set).
