SOURCE: lg plasma

there are 2 types of flicker, one is the lamps that drive the display and the second is the sync signal of the video.
I assume the video sync is the flicker you see,
I would try connecting a different way to make sure it is not the tv,
connect using the aux /rca connectors to cable box.
and or connect using the cable direct bypassing the cable box.
I have seen several complaints about the hdmi cable signal being incorrect in some way,
this is the same issue that the svideo connector had in its early adoption signal was too hot or too low.
another thing to watch out for is the low light sensor on the front of tv if it gets an incorrect reading it can flicker the back light though it should be slow in doing so.
some times the flicker you see is not flicker but ac running through the sides of the picture from an ungrounded cable source.
how does it perform if you play a dvd player , with and without the cable box connected.

SOURCE: what kind of connector do I use to connect a dell

If your computer supports a HDMI connection that would be your best solution. If not then I would go with a DVI to HDMI cable.

SOURCE: Hi, I have bought LG LCD

Hi Jatinder Kumar ,
Yes you can connect your computer output to lcd tv through dvi-hdmi cable or vga-hdmi cable.
1. Connect to HDMI (DVI) : just plug in HDMI (DVI) out of PC or laptop to HDMI or DVI TV. Than select source from HDMI.
2. Connect to PC : Plug D sub to TV, select PC in.

I hope that will help you.
thanks.

Very light colored verticle (1" wide) ribbon on LG 42" Plasma TV


The TV is design for 16:9 format. The bars appear when the TV off showing that the TV has been watching under channels which is have 4:3 format for long time. The screen was burn out because no sweepping to those area. This is not critical problem but you can do nothing to fix it. To eliminate it a bit you shoud read the manual, I believe it has mentioned how to roll or sweep the screen. For plasma TV, if you keep watching 4:3 channels fomat, you shoud do it one a month within 30'. Good luck

LG PLASMA TV WITH COLOURED LINES OVER SCREEN


If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.

Lg 42PX4dv PC connection


I think the problem is the screen resolution and size of your pc is not matching the resolution size of your tv or is not compatable at the size you have it on or you may have to change to 4:3 ratio from widescreen. In your manual it will tell you the resolution sizes that you tv uses. You would probably be better also using the VGA to DVI lead, thats if it came with the tv (it does in the UK) as it supports higher wide screen resolution, whereas VGA will only support 1024 x 768 or there abouts.
