New vizio 42" is posterizing


I think it cause by vs voltage is high. You can try to decrease the Vs voltage a little bit. You can adjust the voltage while the TV is on. The Vs voltage adjustment is locate in the power supply.

Hi yes i had the same problem and its basically because the tv needs a software upgrade. I contacted argos and they sent an engineer to sort it and he plugged something into the back of the tv to upgrade it. all in all it took 5 mins to do and not had a problem since.

Coloured sparkles appear in dark areas of picture


Sometimes just adjusting the VSCAN voltage inthe set will cure it. Other times it will be a faulty panel. Either case requires a technician to do the repairs.

Lg 42pc1d plasma tv red sparkles


I had the same problem, LG came out and it turned out to be the board that filters out the interference around the screen. I pretty sure that was it, took them 10 mins to fix by replacing a few of the boards inside the screen. Sorry I can't be more specific but its not an unfixable problem, so nothing to worry about.

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 :-)
