When i switch on my LG GX300 Moblie there is no display, except a white colored screen with black cracked patterns..this problem arised today morning(yest. night d phone was kept for overnight charging-9 hrs.) the black patterns are visible even when mob. is switched off. the handset is 3 months old. Can it be a Display problem? Plz assist me with a fix.

I think you need to check the color settings on your new LG TV and ensure all cables are securely connected. If the issue persists, you don't have further options except to contact LG support for assistance.

Hello
You haven't given the exact model number ot your LG DVD, so I can only give you a general solution to this problem.
Get into its meny, surf through, come to SYSTEM adjust window, change the system. If a NTSC system recorded disc played with PAL system adjustment with DVD, there will be only black/white pciture, and vice versa.
Adjust it to the color system thathave been adopted your country. this must solve the problem. OK.

You need to check your CPU temperature maybe it overheat need to cool down for 5 mins. Your CPU need some maintenance for cleaning.

LG 50PC5D-UL Plasma TV.... While playing XBox360 the screen just shrunk to the top 3" as though some one was holding a towel over the bottom portion of the screen. I have unplugged all inputs and the unit. I have let it cool down. Still it remains in this condition. I can't see the menu because it's in the portion of the screen that is "blacked out". What do I do?

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.

Bad chroma processor...accordianman

It sounds like the circuitry which actuates the color drives for the screen are not working, this would ba analogous to adjusting for a B&W picture on a color TV you have color but the screen shows black and white. I would get a schematic for this set and measure the voltages on the color processor that connects to the screen since you know that the external jack has color. If possible I can help you troubleshoot this, if you need me to help out.
