Question about Samsung SCH-u740 Cellular Phone

No picture in horizontal mode

I've had this phone 8 months and today when I flipped it to horizontal mode the screen went black and no picture or anything will come up. It's just black in horizontal mode, but the screen still works in the regular mode.

    Same problem with black screen in horizontal mode. Phone is fine in vertical orientation, but I can't seem to use the horizontal keypad. I had this problem a few weeks ago but I 'jiggled' the screen a bit and it came back.

    I'm having the same problem, except I've only had my phone for 2 days. The picture returned when I jiggled it, but then it went black again!

Hi Sharon,

I have the same exact TV and the same exact problem....except today the screen went black and I no longer get a picture from any source. I've had the TV for exactly 13 months. IF you've had your TV for less time, I'd return it.

My motorola v557 cell phone doesn't light up. how


there is nothing wrong with your screen, the problem is from the flex that connects your screen to the phone's main board. This flex must have worn out that's why your screen is not displaying any picture.

The problem is common with flip and slide phones. The flex gets worn out as a result of constant opening and close of the flip or slide phone.

I would urge you to replace the flex and I am assuring you that your screen will display picture again. You might also be lucky to find out that the flex is not well fix, that is, it may have loosed contact.

If you cannot change the flex yourself, maybe you should take the phone to a local repairer within your vicinity, so that the flex can be fixed/replaced.

Good luck.

No Picture but I have Sound

If your TV uses the CTC 203 chassis or similar one, you more than likely have a loose solder joint on the horizontal output transistor base circuit. It's a little inductor (coil covered with red epoxy about 1/2 in. long). If this coil opens up or stops making connection, you lose the horizontal drive pulse to the horizontal output transistor thus causing the screen to go black due to the loss of high voltage.
