Vscan voltages on LG Plasma

I have seen a post on your website that suggests changing the voltage by 10v on the power supply to cure sparkles. Do you know if this actually works?

    Any idea how hard it will be to get a hold of the firmware update? My local repair guy said that sometimes LG won't provide that. Any suggestions .. AND ... any idea how much the average cost to have this procedure done is?

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.

I´ve just fix my 50" inch LG plasma by turning the VSCAN voltage thats at the back of the tv. I did go several times with my vendor and he only said the red dots were dead pixels and the guarantie didnt cover that. So I went to the magic of google and found out that it was as you all said "a voltage problem" and it could be solve by turning the VSCAN switch. I did took a lot of care, cause if you touch anything that you are not supposed to you can frie your tv. I am now whatching it and so far so good.. I guess better than when it was new.

I'll give you the link i used for it.

42" plasma worked fine this


Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps

if otherwise the power supply board is faulty you can try websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Error diffusion on Samsung 50" PLASMA TV


Yes the diffusion problem on your tv is due to the pdp panel aging. What you can try is readjusting the VSCAN voltage, there is a test point marked VSCAN using a DVM you can first check the voltage, should be around -- 190 turn the adjustment counter clockwise this should reduce the voltage, watcthing the picture turn control untill the sparkling pixels stop. That should do it. The panel is starting to age this may occur again until you can't adjust it out meaning a bad panel.

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.

Try to reduce the Vs voltage about 5-10V below its spec value. Vs is from the Power Supply board. The spec value of Vs was printed on the back of PDP panel. (You need to open the back cover)

V scan voltage


Try to adjust the V scan voltage down about 5-10V. If still not working, also try to adjust the Vs voltage down about 5-10V.
