I amj thinking of buying a second hand lg plasma tv, but there is little white sparkly dots on the picture, mainly on the blackest bit of the picture. Is it worth buying it or not? thanx gill.


I realize that this is a old post, but for the sake of anyone else with this issue; I'm visiting my mother and found that she has the same issue. After some investigation, I've been told that this is an issue with something called the "Control PC".

The service tech told me that if it was colored dots, the issue is the "Y Sustain", but white dots are due to the Control PC.

Rough estimate for repair would be in the range of $300 - $400, for a repairman to come out and fix it.

White dots in plasma tv


The only thing you can try is to adjust the tiny control on the Y board, if you want to try do this. Open the set , set it up so you can watch it with the back off. now looking at the back on the left side you will see a circuit board larger connected to a smalled one or two that go to the screen edge . on the larger board look for a few small controls, mark their positions with a dark sharpy then turn each a little while looking at the dots to see if one makes them better or worse. If one control effects the dots try to center it for the least amount of dots, if no effect is observed when a control is turned return it the original position that you mark before starting. if the dots do not clear either the Y board is bad or the whole scfreen is defective.

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.

LG 42in plasma - Green dots on HDMI channel


The diffusion is slightly out of adjusment. This timing adjustment is difficult and on a single scan LG plasma the proper operation requires voltage settings first, then a scope to finalize the adjustment. I have good luck with this alignment by eye but have had alot of practice. This will require taking the back off and a person with the technical background to set this alignment properly. Sorry no easy fix.

Flickering dots


The symptom you described is called diffusion. A simple alignment, normally in the power supply takes care of this problem. For the nearest Authorized Service Center near you contact Toshiba online at: http://webmail.tacp.com/service/servcntr.nsf/$$Search?OpenForm Hope this helps
