I have an lg pdp42v7 that suffers from pixel sparkle is there a remedy for this or is tv on its way out regards harry

Not sure what you call "sparkle on the screen" could you post a picture of what it looks like.

the pixel is "locked" on; using a tissue and, a pencil eraser atempt to "rubout" the pixel to reset it.
Use very little pressure!!! when you do this!

Hi Harry,
From the Picture Menu, the option at the bottom is Trumotion demo. Highlight this and press enter, turn demo off, press return.
Let me know if this helps and please rate this solution.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/jason_77a19afa8d604dee

I'm not really sure what causes this but I might be able to help.
I have an LG 42 plasma which had the same problem. In my case I removed the video and the tuner board (they both were mounted on the same frame which was screwed on the tv chassis) and installed them in a "wooden box" so that there would be no electrical contact with the rest of the chassis except from the cables connected to them. It now works fine.

is it pixels burnt or a sparkling effect there is a fix for the sparkling effect but if you are having burnt pixles it may be screen replacement

Available from tritronicsinc.com are the following:

6871QZH041A Zenith/LG Z-SUS Cost: $137.44
6871QYH036A Zenith/LG Y-SUS Cost: $238.38
6871QYH053A Zenith/LG Control Board Cost: $189.39

Hope this helps,

THIS PHENOMENON IS A CHARACTERISTIC OF PLASMA TV SETS...KNOWN AS DIFFUSION ERRORS OR COMMONLY..SPARKLING...ON LG SETS...THE PANEL VOLTAGES MUST BE CHECKED AND ADJUSTED IF NOT WITHIN .5 V...PLUS OR MINUS..Vs...and Va...THE OTHER ADJUSTMENTS ARE ON THE Y-SUS BOARD..Vset DOWN...Vset up...RAMP up...RAMP down...these should be adjusted by professional tv personnel with experence...JOE ACE

hi i repair some plasma's at my shop. it is 75% to 85% chance that this pdp42v7 repair kit availible from me at www.microclick.co.uk/pdp42v7.asp would resolve your problem.

Are your sparkles mainly red pixels flashing randomly over the TV screen, especially over darker areas? If so your sparkles are I believe a discharge problem, and can be fixed with a firmware upgrade, which I think resets and corrects the voltage and removes the sparkles, which is caused by misfiring of the gases produced with plasma TV's. I have had my TV repaired with a firmware upgrade, which takes only 10-15 minutes and is reasonably cheap repair, and now the TV looks great, no more sparkles. Don't play around with the voltages let the pros fix it, also beware! leave this too long and it can become permanent, and need a new screen which is half the price of the a new TV.

Makes you wonder why nobody is taking on the problem, doesn't it?
Well , to the best of my knowledge, it is because nobody really can.
To understand why you have to understand what do they sparkles come from.
They are random electricity discharges coming from capacitors or other components that act like capacitors, but mostly capacitors.
When laymen hear about capacitors they usually associate the word with bulged electrolytic capacitors, which often cause problems in electronics of all kind.
Well this time it isn't about them.
It's about all other capacitors - or other components exposing similar qualities - which are installed on the board. Most of them are small filter capacitors put in parallel to the big ones or to other passive components such as diodes and resistors.
The excessive heat developed by the sustain boards damages those capacitors. It hardens the electrostatic material they are made of and small breaks in it start occurring at voltages that shouldn't otherwise be causing issues.
The trouble is, they can be everywhere. You can't just pinpoint which ones were caught at fault and causing the sparkles.
When it gets REALLY bad eventually the whole capacitor burns and either shorts or, more commonly, just breaks.
Believe it or not I've seen a board that exploded before my very eyes and , after the explosion, started working LIKE A CHARM!
Turned out a small filter capacitor had blown. It as not essential for the board's functionality and after being problematic for so long and causing image deffects it had eventually shorted completely and literally exploded.
Luckily, the short it had created was too short in time and apparently in a circuit that could take the load for a short while without getting damaged.
So after it blew everything worked just great!
it's a real story from my repair experience.
Hope this helps all consumers, DIY enthusiasts and competitors alike :-)
