LG MODEL#RM-26LZ30 PICTURE seems scrambled and vertical lines trough the middle of screen


DEPENDS ON WHICH BOARD THAT NEEDS REPLACING. Look on Shopjimmy.com they list boards and parts. If you know how to solder I would first resolder boards and check for Bad Capaciotrs they will be puffed up on Top.

LG 8300 phone the display screen is distorted / scrambled


Hello,

The problem with your phone is that the flex on your phone screen is malfunctioning, that is why the screen is distorted.

All you will need to do is to change the flex on your phone screen because it is now faulty.

Change the flex of your phone screen as advice and you will see that your phone screen will be back to normal.

Take care.

Intermittent pixel scrambling on screen (have AT&T u-verse/ Sanyo DS32920 Flat panel 32" TV)


Usually the result of a weak or interruption of the signal. If it occurs on all channels, look into getting an inline amplifier. If you have several splitters going to different tv's or a multiple splitter, the signal is degraded each time the signal is split. You can test this be temporarily making a direct link to the TV from the cable source. If it clears up, then you know you need to amplify the signal.
