The issue is the voltage is not tuned properly for the panel, could be due to panel aging or gradual component failure.

LG W2361V 23 Vga to HDMI Cable Not Working


You have a cable problem as no such thing as a VGA to HDMI cable exists.

HDMI is a didital signal and is thus not compatable with an anolog VGA signal. HDMI to DVI cables however do exist as both are digital signals.

Hope this helps.

I have dots running across the screen


If the dots are red and green, that's normal. Just enjoy your hd picture. actually, I think the dots make it look clearer. The only time I can really see them is when the screen is black.

Plasma tv has little red dots in the black


This problem (known as sparkles) can be cured by adjusting the ramp control on the Y-Sustain board. If this does not cure the dots then there is a software remedy for the control board which an LG repair centre could fix. Failing that a replacement board is required. The orbitor & whitewash are like screen savers to help to prevent a screen burn from a permanently displayed image.

Lg plasma tv 42 px5d


Most times this can be corrected by the correct alignment of the diffusion. The unfortunate part is that will require a tech that knows how to set all of the power supply voltages and then align the diffusion pots on the ysus pwb. This could mean a defective ysus bd. but most times the alignment will correct this problem.

This problem cannot be corrected without disassembly, and the proper adjustment of the power supply voltages and the diffusion adjusment of the ysus pwb. This will take a qualified service tech that understands plasma technology.
